fc28c39f0e mtd: maps: add mtd-ram support to physmap_of
Use physmap_of to access RAMs as mtd and add documenation for it. This approach
is a lot less intrusive as adding an of-wrapper around plat-ram.c. As most
extensions of plat-ram.c (e.g. custom map-functions) can't be mapped to the
device tree anyhow, extending physmap_of seems to be the cleanest approach.

Tested with a phyCORE-MPC5121e.

ed88bae691 leds: Add options to have GPIO LEDs start on or keep their state
There already is a "default-on" trigger but there are problems with it.

For one, it's a inefficient way to do it and requires led trigger support
to be compiled in.

But the real reason is that is produces a glitch on the LED.  The GPIO is
allocate with the LED *off*, then *later* when the trigger runs it is
turned back on.  If the LED was already on via the GPIO's reset default or
action of the firmware, this produces a glitch where the LED goes from on
to off to on.  While normally this is fast enough that it wouldn't be
noticeable to a human observer, there are still serious problems.

One is that there may be something else on the GPIO line, like a hardware
alarm or watchdog, that is fast enough to notice the glitch.

Another is that the kernel may panic before the LED is turned back on, thus
hanging with the LED in the wrong state.  This is not just speculation, but
actually happened to me with an embedded system that has an LED which
should turn off when the kernel finishes booting, which was left in the
incorrect state due to a bug in the OF LED binding code.

We also let GPIO LEDs get their initial value from whatever the current
state of the GPIO line is.  On some systems the LEDs are put into some
state by the firmware or hardware before Linux boots, and it is desired to
have them keep this state which is otherwise unknown to Linux.

This requires that the underlying GPIO driver support reading the value of
output GPIOs.  Some drivers support this and some do not.

The platform device binding gains a field in the platform data
"default_state" that controls this.  There are three constants defined to
select from on, off, or keeping the current state.  The OpenFirmware
binding uses a property named "default-state" that can be set to "on",
"off", or "keep".  The default if the property isn't present is off.

5fe23c7f51 sdhci: Add support for hosts that are only capable of 1-bit transfers
Some hosts (hardware configurations, or particular SD/MMC slots) may
not support 4-bit bus. For example, on MPC8569E-MDS boards we can
switch between serial (1-bit only) and nibble (4-bit) modes, thought
we have to disable more peripherals to work in 4-bit mode.

Along with some small core changes, this patch modifies sdhci-of
driver, so that now it looks for "sdhci,1-bit-only" property in the
device-tree, and if specified we enable a proper quirk.

"fsl,qe-num-snums", and set 28 as the default number of SNUMs so that it is
compatible with the old QE chips' device trees which don't have this new
property. The macro QE_NUM_OF_SNUM is defined as the maximum number in QE
snum table which is 256.

Also we update the snum_init[] array with 18 more new SNUMs which are
confirmed to be useful on new chip.

a7d878af94 leds: Add openfirmware platform device support
Add bindings to support LEDs defined as of_platform devices in addition to
the existing bindings for platform devices.

New options in Kconfig allow the platform binding code and/or the
of_platform code to be turned on.  The of_platform code is of course only
available on archs that have OF support.

The existing probe and remove methods are refactored to use new functions
create_gpio_led(), to create and register one led, and delete_gpio_led(),
to unregister and free one led.  The new probe and remove methods for the
of_platform driver can then share most of the common probe and remove code
with the platform driver.

The suspend and resume methods aren't shared, but they are very short.  The
actual led driving code is the same for LEDs created by either binding.

The OF bindings are based on patch by Anton Vorontsov
<avorontsov@ru.mvista.com>.  They have been extended to allow multiple LEDs
per device.

4d7902f22b gianfar: Fix stashing support
Stashing is only supported on the 85xx (e500-based) SoCs.  The 83xx and 86xx
chips don't have a proper cache for this.  U-Boot has been updated to add
stashing properties to the device tree nodes of gianfar devices on 85xx.  So
now we modify Linux to keep stashing off unless those properties are there.

34df9f69a4 powerpc/5200: update device tree binding documentation
This patch updates the mpc5200 binding documentation to match
actual usage conventions, to remove incorrect information, and
to remove topics which are more thoroughly described elsewhere.

a808ad3b0d [MTD] [NAND] ndfc driver
The current ndfc driver only compiles under arch/ppc. This arch was
removed from the kernel. I notice the event entry for the ndfc in
Kconfig has been removed in 2.6.28.

This patch converts the ndfc to a proper OF (OpenFirmware) driver. I
can give a working example of the DTS if needed.

The patch has been in production use on the PIKA Warp Appliance and is
in use by others. The Warp basically boots from NAND, so the ndfc driver
is very important to us.

94409d6e10 powerpc: Add device tree bindings for BCSR GPIO banks
The patch adds bindings for BCSR GPIO banks, the bindings are used to
describe particular BCSR registers that act as simple GPIO controllers.
These GPIO banks might control power switches, SPI chip-selects, LEDs,
etc.

While at it, also fix "length" spelling error in the PIXIS FPGA
bindings.

b31a1d8b41 gianfar: Convert gianfar to an of_platform_driver
Does the same for the accompanying MDIO driver, and then modifies the TBI
configuration method.  The old way used fields in einfo, which no longer
exists.  The new way is to create an MDIO device-tree node for each instance
of gianfar, and create a tbi-handle property to associate ethernet controllers
with the TBI PHYs they are connected to.

ec5d7657f7 powerpc: Repair device bindings documentation
Commit d0fc2eaaf4 "powerpc/fsl: Refactor
device bindings" split out a number of device bindings from
booting-without-of.txt into separate files.  Having them all in one file
was a frequent source of merge conflicts.

However, in the next merge, 49997d7515, there
was another conflict.  Some of the bindings removed from
booting-without-of.txt were mistakenly added back in and the copies in
dts-bindings were kept as well.

This patch re-removes "Freescale Display Interface" and "Freescale on board
FPGA" and fixes the table of contents.

fd657efc67 powerpc: Remove device_type = "board_control" properties in .dts files
We don't want to encourage the bogus device_type usage.

The device type isn't used in the code, so we can simply remove it from
the documentation and dts files.

Boards should specify proper compatible entries instead.
