84b2170109 ARM: S3C24XX: Add SPDX license identifiers
Replace GPL license statements with SPDX license identifiers (GPL-2.0
and GPL-2.0+).  The h1940-bluetooth.c was licensed under GPL-1.0.  This
also adds GPL-2.0 to few files lacking license statement.

8c60969856 ARM: SoC platform updates for 4.15
Most of the commits are for defconfig changes, to enable newly added
 drivers or features that people have started using. For the changed
 lines lines, we have mostly cleanups, the affected platforms are
 OMAP, Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions.
 
 The largest single change is the introduction of the TI "sysc" bus
 driver, with the intention of cleaning up more legacy code.
 
 Two new SoC platforms get added this time:
 - Allwinner R40 is a modernized version of the A20 chip, now
   with a Quad-Core ARM Cortex-A7. According to the manufacturer,
   it is intended for "Smart Hardware"
 - Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family
   of chips meant for managed gigabit ethernet switches, based
   around a Cortex-A9 CPU.
 
 Finally, we gain SMP support for two platforms: Renesas R-Car E2
 and Amlogic Meson8/8b, which were previously added but only supported
 uniprocessor operation.

b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

This patch changes ecc_mode to NAND_ECC_HW which restores proper
operation of the NAND flash memory.

We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.

f991ce429a ARM: s3c24xx: make H1940BT depend on RFKILL
Bluetooth is only supported when network support is part of the kernel,
so it is a bit pointless to build the hi1940-bt support without networking.
If we try anyway, we get a Kconfig warning:

warning: (TOSA_BT && H1940BT) selects RFKILL which has unmet direct dependencies (NET)

This turns the 'select' into 'depends on' as Krzysztof suggested when
I first sent a fix.

66f2c6d952 ARM: SoC platform updates for v4.9
These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - We get support for running in big-endian mode on two platforms:
   sunxi (Allwinner) and s3c24xx (old Samsung).
 
 - The recently added Uniphier platform now uses standard PSCI
   methods for SMP booting and we remove support for old bootloader
   versions that did not support it yet.
 
 - In sunxi, we gain support for the "Nextthing GR8" SoC, which
   is a close relative of the Allwinner A13 and R8 chips.
 
 - PXA completes its move over to the generic dmaengine framework
   and removes its old private API
 
 - mach-bcm gains support for BCM47189/BCM53573, their first ARM
   SoC with integrated 802.11ac wireless networking.

dma_slave_map array via the platform data. This is needed to
be able to use the new, simpler dmaengine API [1].
I used the virtual DMA channels as a parameter for the dma_filter
function. By doing that, I could reuse the existing filter function in
drivers/dma/s3c24xx-dma.c.

I have tested this on my mini2440 board with the audio driver.
According to my observations, dma_request_slave_channel in the
function dmaengine_pcm_new in the file
sound/soc/soc-generic-dmaengine-pcm.c now returns a valid DMA channel
whereas before no DMA channel was returned at that point.

Entries for DMACH_XD0, DMACH_XD1 and DMACH_TIMER are missing because I
don't realy know which driver to use for these.

2d0ab9c36f ARM: S3C24XX: Add missing DMA device for Mini2440 board
Addition of s3c2440_device_dma was missed during conversion
from the Samsung legacy to the regular DMA API.
Add it so any devices using DMA, e.g I2S controller can
work properly.

The dma_mask assignments seem to be missed during refactoring

failures. Without this patch sound is broken on s3c24xx
with errors reported like:

6f888fe31d ARM: SoC cleanups for v4.8
The cleanup branch keeps going down in size as we've completed a lot of

 A handful of changes this time around, some of the themes or larger sets are:
 
  - A bunch of i.MX cleanups around platform detection, init call cleanups
  - Misc fixes of missing/implicit includes
  - Removal of ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB

5c34a4e89c ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

15925cfcf8 ARM: s3c24xx: Avoid warning for inb/outb
s3c24xx implements its own inb/outb macros, but the implementation
prints warnings when the port number argument is not a 32-bit scalar:

drivers/scsi/pas16.c: In function 'NCR5380_pwrite':
arch/arm/mach-s3c24xx/include/mach/io.h:193:68: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
 #define __ioaddrc(port) ((__PORT_PCIO(port) ? PCIO_BASE + (port) : (void __iomem *)(port)))

This slightly modifies the definition of the __ioaddrc macro to avoid
the warning.

ce7f8ce016 ARM: SAMSUNG: Remove unused register offset definition
This patch cleans up various map.h under mach-exynos, mach-s3c24xx and
plat-samsung by removing unused register offset. This patch also does a
minor nitpick of changing EXYNOS4 to EXYNOS from comment section of
header file "mach-exynos/include/mach/map.h".

8db9a2026d ARM: s3c24xx: fix unused gta02_configure_pmu_for_charger warning
gta02_configure_pmu_for_charger is only used when CONFIG_PCF50633_ADC
is set, and otherwise we get a warning about an unused symbol:

arch/arm/mach-s3c24xx/mach-gta02.c:158:1: warning: 'gta02_configure_pmu_for_charger' defined but not used [-Wunused-function]
 gta02_configure_pmu_for_charger(struct pcf50633 *pcf, void *unused, int res)

This adds an #ifdef to shut up the warning.

16560854d0 ARM: s3c24xx: allow selecting S3C2440_XTAL_16934400 for s3c2442
The S3C2440_XTAL_16934400 and S3C2440_XTAL_12000000 symbols are used
for both s3c2442 and s3c2440, but Kconfig only allows it to be selected
if CPU_S3C2440 is enabled, which can lead to a warning otherwise:

warning: (MACH_RX1950) selects S3C2440_XTAL_16934400 which has unmet direct dependencies (ARCH_S3C24XX && CPU_S3C2440)

This changes the dependencies to make it possible also for CPU_S3C2442-only
configurations.

bde491fde0 ARM: s3c24xx: don't select EEPROM_AT24
EEPROM_AT24 depends on both I2C and SYSFS. We have in the past
added I2C 'select' statements to avoid build problems with the
first, but we still get a warning because of the second:

warning: (MACH_DAVINCI_EVM && MACH_SFFSDR && MACH_DAVINCI_DM6467_EVM && MACH_DAVINCI_DM365_EVM && MACH_DAVINCI_DA830_EVM && MACH_MITYOMAPL138 && MACH_MINI2440) selects EEPROM_AT24 which has unmet direct dependencies (I2C && SYSFS)

This removes the 'select' statements again, and forces users to
enable the driver in their configuration files, as we do for
most other drivers.

26922c5909 ARM: s3c: simplify s3c_irqwake_{e,}intallow definition
For a long time, gcc has warned about odd configurations on s3c64xx:

In file included from arch/arm/plat-samsung/pm.c:34:0:
arch/arm/mach-s3c64xx/include/mach/pm-core.h:61:0: warning: "s3c_irqwake_eintallow" redefined
 #define s3c_irqwake_eintallow ((1 << 28) - 1)
In file included from arch/arm/plat-samsung/pm.c:33:0:
arch/arm/plat-samsung/include/plat/pm.h:49:0: note: this is the location of the previous definition
 #define s3c_irqwake_eintallow 0

The definitions of s3c_irqwake_intallow and s3c_irqwake_eintallow are a
bit consistent between the various platforms. Things have become easier
now that it's only s3c24xx and s3c64xx that use them at all, so I've tried
to rearrange the definitions to make it more obvious what is going on.

62f49ee26f cpufreq: s3c24xx: Do not mark s3c2410_plls_add as __init
s3c2410_plls_add is a device notifier that may be called at runtime and
is correctly not marked __init. However it calls s3c_plltab_register()
which is marked __init, and that triggers a build error when we are
checking for section mismatches:

WARNING: vmlinux.o(.text+0x195e0): Section mismatch in reference from the function s3c2410_plls_add() to the function .init.text:s3c_plltab_register()
The function s3c2410_plls_add() references
the function __init s3c_plltab_register().
This is often because s3c2410_plls_add lacks a __init
annotation or the annotation of s3c_plltab_register is wrong.

This removes the __init annotation from s3c2410_plls_add as well as the
__initdata section annotations from s3c2440_plls_12 and s3c2440_plls_169344,
which in turn are referenced from s3c2410_plls_add.
