From cef57541cdc079165e9af419ccacd36dce863d3a Mon Sep 17 00:00:00 2001
From: Adam Williamson <awilliam@redhat.com>
Date: Wed, 19 Feb 2020 17:50:07 +0100
Subject: [PATCH] compat_ioctl, cdrom: Replace .ioctl with .compat_ioctl in
four appropriate places
Arnd Bergmann inadvertently typoed these in d320a9551e394 and
64cbfa96551a; they seem to be the cause of
https://bugzilla.redhat.com/show_bug.cgi?id=1801353 , invalid
SCSI commands when udev tries to query a DVD drive.
[arnd] Found another instance of the same bug, also introduced
in my compat_ioctl series.
Fixes: d320a9551e39 ("compat_ioctl: scsi: move ioctl handling into drivers")
Fixes: 64cbfa96551a ("compat_ioctl: move cdrom commands into cdrom.c")
Fixes: c103d6ee69f9 ("compat_ioctl: ide: floppy: add handler")
Link: https://bugzilla.redhat.com/show_bug.cgi?id=1801353

Depending on bcm2711's revision its emmc2 controller might have
different DMA constraints. Raspberry Pi 4's firmware will take care of
updating those, but only if a certain alias is found in the device tree.
So, move emmc2 into its own bus, so as not to pollute other devices with
dma-ranges changes and create the emmc2bus alias.
Based in Phil ELwell's downstream implementation.

Commit a5b6b67364cb ("arm64: tegra: Add ID EEPROM for Jetson TX1
module") populated the EEPROM on the Jetson TX1 module, but did not
enable the corresponding I2C controller. Enable the I2C controller so
that this EEPROM can be accessed.

WARNING KERN at24 0-0057: 0-0057 supply vcc not found, using dummy regulator
For both of these platforms the EEPROM is powered by the main 1.8V
supply rail and so populate the supply for these devices to fix these
warnings.

The following warning is observed on the Jetson TX2 platform ...
WARNING KERN tegra-sor 15540000.sor: 15540000.sor supply \
vdd-hdmi-dp-pll not found, using dummy regulator
The problem is caused because the regulator for the SOR device is
missing the '-supply' suffix in Device-Tree. Therefore, add the
'-supply' suffix to fix this warning.

The property is needed in order to trigger VL805's firmware load. Note
that there is a gap between the property introduced and the previous
one. This is also the case downstream.

On the Raspberry Pi 4, after a PCI reset, VL805's firmware may either be
loaded directly from an EEPROM or, if not present, by the SoC's
VideCore. The function informs VideCore that VL805 was just reset, or
requests for a probe defer.
Based on Tim Gover's downstream implementation.

xHCI's PCI fixup, run at the end of pcie-brcmstb's probe, depends on
RPi4's VideoCore firmware interface to be up and running. It's possible
for both initializations to race, so make sure it's available prior to
starting.

On the Raspberry Pi 4, after a PCI reset, VL805's firmware may either be
loaded directly from an EEPROM or, if not present, by the SoC's
VideCore. Inform VideCore that VL805 was just reset.
Also, as this creates a dependency between XHCI_PCI and VideoCore's
firmware interface, reflect that on the firmware interface Kconfg.

Changes since v4:
- Do not split up error message
Changes since v3:
- Add more complete error message
Changes since v1:
- Make RASPBERRYPI_FIRMWARE dependent on this quirk to make sure it
gets compiled when needed.

Use the control interface (field 'components' in the info structure)
to pass the I/O configuration details. The goal is to replace
the card long name with this.

Subject: [PATCH 2/2] arm64: dts: allwinner: a64: Add MBUS controller node
A64 contains MBUS, which is the bus used by DMA devices to access
system memory.
MBUS controller is responsible for arbitration between channels based
on set priority and can do some other things as well, like report
bandwidth used. It also maps RAM region to different address than CPU.

Subject: [PATCH 3/3] arm64: dts: allwinner: Add initial support for Pine64
PinePhone
At the moment PinePhone comes in two slightly incompatible variants:
- 1.0: Early Developer Batch
- 1.1: Braveheart Batch
There will be at least one more incompatible variant in the very near
future, so let's start by sharing the dtsi among multiple variants,
right away, even though the HW description doesn't yet include the
different bits.
The differences between 1.0 and 1.1 are: change in pins that control
the flash LED, differences in modem power status signal routing, and
maybe some other subtler things, that have not been determined yet.
This is a basic DT that includes only features that are already
supported by mainline drivers.

Subject: [PATCH 2/2] arm64: dts: allwinner: a64: add support for PineTab
PineTab is a 10.1" tablet by Pine64 with Allwinner A64 inside.
It includes the following peripherals:
USB:
- A microUSB Type-B port connected to the OTG-capable USB PHY of
Allwinner A64. The ID pin is connected to a GPIO of the A64 SoC, and the
Vbus is connected to the Vbus of AXP803 PMIC. These enables OTG
functionality on this port.
- A USB Type-A port is connected to the internal hub attached to the
non-OTG USB PHY of Allwinner A64.
- There are reserved pins for an external keyboard connected to the
internal hub.
Power:
- The microUSB port has its Vbus connected to AXP803, mentioned above.
- A DC jack (of a strange size, 2.5mm outer diameter) is connected to
the ACIN of AXP803.
- A Li-Polymer battery is connected to the battery pins of AXP803.
Storage:
- An tradition Pine64 eMMC slot is on the board, mounted with an eMMC
module by factory.
- An external microSD slot is hidden under a protect case.
Display:
- A MIPI-DSI LCD panel (800x1280) is connected to the DSI port of A64 SoC.
- A mini HDMI port.
Input:
- A touch panel attached to a Goodix GT9271 touch controller.
- Volume keys connected to the LRADC of the A64 SoC.
Camera:
- An OV5640 CMOS camera is at rear, connected to the CSI bus of A64 SoC.
- A GC2145 CMOS camera is at front, shares the same CSI bus with OV5640.
Audio:
- A headphone jack is conencted to the SoC's internal codec.
- A speaker connected is to the Line Out port of SoC's internal codec, via
an amplifier.
Misc:
- Debug UART is muxed with the headphone jack, with the switch next to
the microSD slot.
- A bosch BMA223 accelerometer is connected to the I2C bus of A64 SoC.
- Wi-Fi and Bluetooth are available via a RTL8723CS chip, similar to the
one in Pinebook.
This commit adds a basically usable device tree for it, implementing
most of the features mentioned above. HDMI is not supported now because
bad LCD-HDMI coexistence situation of mainline A64 display driver, the
front camera currently lacks a driver and a facility to share the bus
with the rear one, and the accelerometer currently lacks a DT binding.

Allwinner A64 SoC has separate supplies for PC, PD, PE, PG and PL.
VCC-PC and VCC-PG are supplied by ELDO1 at 1.8v.
VCC-PD is supplied by DCDC1 (VCC-IO) at 3.3v.
VCC-PE is supplied by ALDO1, and is unused.
VCC-PL creates a circular dependency, so it is omitted for now.

Subject: [PATCH 6/8] arm64: dts: allwinner: pinebook: Fix backlight regulator
The output from the backlight regulator is labeled as "VBKLT" in the
schematic. Using the equation and resistor values from the schematic,
the output is approximately 18V, not 3.3V. Since the regulator in use
(SS6640STR) is a boost regulator powered by PS (battery or AC input),
which are both >3.3V, the output could not be 3.3V anyway.

From: Jeff Brasen <jbrasen@nvidia.com>
To support booting NVIDIA Tegra platforms with either Device-Tree or
ACPI, create a Tegra specific 8250 serial driver that supports both
firmware types. Another benefit from doing this, is that the Tegra
specific codec in the generic Open Firmware 8250 driver can now be
removed.

Subject: [PATCH] ARM64: tegra: Fix Tegra194 PCIe compatible string
If the kernel configuration option CONFIG_PCIE_DW_PLAT_HOST is enabled
then this can cause the kernel to incorrectly probe the generic
designware PCIe platform driver instead of the Tegra194 designware PCIe
driver. This causes a boot failure on Tegra194 because the necessary
configuration to access the hardware is not performed.
The order in which the compatible strings are populated in Device-Tree
is not relevant in this case, because the kernel will attempt to probe
the device as soon as a driver is loaded and if the generic designware
PCIe driver is loaded first, then this driver will be probed first.
Therefore, to fix this problem, remove the "snps,dw-pcie" string from
the compatible string as we never want this driver to be probe on
Tegra194.
Fixes: 2602c32f15e7 ("arm64: tegra: Add P2U and PCIe controller nodes to Tegra194 DT")

The Jetson TX1 dev kit doesn't ship with a screen by default and if
it's not there it appears to crash on boot so disable them both by
default until we work out the problem.

Subject: [PATCH] usb: host: xhci-tegra: set MODULE_FIRMWARE for tegra186
Set the MODULE_FIRMWARE for tegra186, it's registered for 124/210 and
ensures the firmware is available at the appropriate time such as in
the initrd, else if the firmware is unavailable the driver fails with
the following errors:
tegra-xusb 3530000.usb: Direct firmware load for nvidia/tegra186/xusb.bin failed with error -2
tegra-xusb 3530000.usb: failed to request firmware: -2
tegra-xusb 3530000.usb: failed to load firmware: -2
tegra-xusb: probe of 3530000.usb failed with error -2
Fixes: 5f9be5f3f899 ("usb: host: xhci-tegra: Add Tegra186 XUSB support")

probe failure.
Finally, ensure that the vddio regulator is disabled in the driver

Customers of our "Revolution Pi" open source PLCs (which are based on
the Raspberry Pi) have reported random lockups as well as jittery eMMC,
UART and SPI latency. We were able to reproduce the lockups in our lab
and hooked up a JTAG debugger:
It turns out that the USB controller's interrupt is already enabled when
the kernel boots. All interrupts are disabled when the chip comes out
of power-on reset, according to the spec. So apparently the bootloader
enables the interrupt but neglects to disable it before handing over
control to the kernel.
The bootloader is a closed source blob provided by the Raspberry Pi
Foundation. Development of an alternative open source bootloader was
begun by Kristina Brooks but it's not fully functional yet. Usage of
the blob is thus without alternative for the time being.
The Raspberry Pi Foundation's downstream kernel has a performance-
optimized USB driver (which we use on our Revolution Pi products).
The driver takes advantage of the FIQ fast interrupt. Because the
regular USB interrupt was left enabled by the bootloader, both the
FIQ and the normal interrupt is enabled once the USB driver probes.
The spec has the following to say on simultaneously enabling the FIQ
and the normal interrupt of a peripheral:
"One interrupt source can be selected to be connected to the ARM FIQ
input. An interrupt which is selected as FIQ should have its normal
interrupt enable bit cleared. Otherwise a normal and an FIQ interrupt
will be fired at the same time. Not a good idea!"
^^^^^^^^^^^^^^^
https://www.raspberrypi.org/app/uploads/2012/02/BCM2835-ARM-Peripherals.pdf
page 110
On a multicore Raspberry Pi, the Foundation's kernel routes all normal
interrupts to CPU 0 and the FIQ to CPU 1. Because both the FIQ and the
normal interrupt is enabled, a USB interrupt causes CPU 0 to spin in
bcm2836_chained_handle_irq() until the FIQ on CPU 1 has cleared it.
Interrupts with a lower priority than USB are starved as long.
That explains the jittery eMMC, UART and SPI latency: On one occasion
I've seen CPU 0 blocked for no less than 2.9 msec. Basically,
everything not USB takes a performance hit: Whereas eMMC throughput
on a Compute Module 3 remains relatively constant at 23.5 MB/s with
this commit, it irregularly dips to 23.0 MB/s without this commit.
The lockups occur when CPU 0 receives a USB interrupt while holding a
lock which CPU 1 is trying to acquire while the FIQ is temporarily
disabled on CPU 1.
I've tested old releases of the Foundation's bootloader as far back as
1.20160202-1 and they all leave the USB interrupt enabled. Still older
releases fail to boot a contemporary kernel on a Compute Module 1 or 3,
which are the only Raspberry Pi variants I have at my disposal for
testing.
Fix by disabling IRQs left enabled by the bootloader. Although the
impact is most pronounced on the Foundation's downstream kernel,
it seems prudent to apply the fix to the upstream kernel to guard
against such mistakes in any present and future bootloader.

From 9ad059ee412caed3fc8666dadf0d2e897d621958 Mon Sep 17 00:00:00 2001
From: Peter Robinson <pbrobinson@gmail.com>
Date: Wed, 18 Dec 2019 08:03:36 +0000
Subject: [PATCH] gpu/drm/v3d: Add ARCH_BCM2835 to DRM_V3D Kconfig
On arm64 the config ARCH_BCM doesn't exist so to be able to
build for platforms such as the Raspberry Pi 4 we need to add
ARCH_BCM2835 similar to what has been done on vc4.
