Add support for the OnePlus 6 and 6T SDM845 devices

Add support for the OnePlus 6 and 6T SDM845 devices

[Caleb Connolly]

Add a device tree with support for the following:
  * Display panel (with the oneplus-6 panel driver)
  * Hardware accelerated graphics
  * Touch screen support with Synaptics rmi4
  * RTC support
  * Remoteprocessors boot and can be interacted with over QRTR.
  * ath10k WLAN using pd-mapper, rmts and tqftpserv daemons
  * Bluetooth
  * Volume / power buttons and OnePlus Tri-State switch are functional
  * USB

The only differences between the devices is the different panels,
fingerprint readers and that the 6T lacks a headphone jack and notification
LED.

Current limitations:
  * Bluetooth does not appear in rfkill, this is most likely the reason
    it doesn't appear in UI bluetooth settings, it can be interacted
    with using bluez-utils bluetoothctl.
  * USB is forced to peripheral mode as cable type detection is broken

[PATCH 1/5] drm/panel/oneplus6: Add panel-oneplus6

[Caleb Connolly]

This commit adds support for the display panels used in the OnePlus 6 /
T devices.

The OnePlus 6/T devices use different panels however they are
functionally identical with much of the commands being shared. The
panels don't appear to be used by any other devices some combine them as
one driver that is specific to the devices.

The panels are: samsung,sofef00
and             samsung,s6e3fc2x01

[PATCH 3/5] arm64: dts: sdm845: add oneplus 6/t devices

[Caleb Connolly]

Add initial support for the OnePlus 6 (enchilada) and 6T (fajita) based
on the sdm845-mtp DT. Support includes:

* Both display panels work
* Touch screen support with rmi4
* RTC support
* Remoteprocs boot and can be interacted with over QRTR.
* WLAN + Bluetooth both work, although bluetooth doesn't appear in
rfkill.
* Volume / power buttons and OnePlus Tri-State switch are functional
* USB gadget support is forced as it doesn't seem to be able to detect
USB cable connect/disconnect, perhaps to do with OnePlus' propriatery
fast charge IC.

The device successfully boots into Phosh using postmarketOS.

[PATCH 5/5] i2c: geni: sdm845: dont perform DMA for the oneplus6

[Caleb Connolly]

The OnePlus 6/T has the same issues as the c630 causing a crash when DMA
is used for i2c, so disable it.

Re: Add support for the OnePlus 6 and 6T SDM845 devices

[Caleb Connolly]

This is V2 of the series, it should have been set in the subject line 
but doesn't seem to have been.

It includes the following changes from V1:

  * Amendments to the panel driver regarding Sam's comments
  * DTS formatting improvements.

Sorry for any confusion caused.
Regards,
Caleb

Add support for the OnePlus 6 and 6T SDM845 devices

[Caleb Connolly]

The OnePlus 6/T handsets are based on the SDM845 platform and were
released in late 2017. Add support for booting with core
functionality including:

 * Display panels and hardware accelerated graphics
 * Touch screen with Synaptics RMI4
 * Modem and other remoteprocessors
 * WiFi / Bluetooth
 * Buttons and OnePlus Tri-State key
 * USB gadget mode

Both devices are almost identical, but use different display panels,
with the 6T lacking a headphone jack and notification LED.

This series depends on the SMMU stream mapping patches which can be
found here:
https://lore.kernel.org/linux-iommu/20201017043907.2656013-1-bjorn.andersson@linaro.org/

The devices will fail early in the boot process otherwise.

Missed here, these patches depend on Bjorns SMMU patches to boot with 
the display enabled, and disabling the display is not possible on newer 
firmware.

Add support for the OnePlus 6 and 6T SDM845 devices

[Caleb Connolly]

The OnePlus 6/T handsets are based on the SDM845 platform and were
released in late 2017.

Add a device tree with support for the following:
  * Display panel (with the oneplus-6 panel driver)
  * Hardware accelerated graphics
  * Touch screen support with Synaptics rmi4
  * RTC support
  * Remoteprocessors boot and can be interacted with over QRTR.
  * ath10k WLAN using pd-mapper, rmts and tqftpserv daemons
  * Bluetooth
  * Volume / power buttons and OnePlus Tri-State switch are functional
  * USB

The only differences between the devices is the different panels,
fingerprint readers and that the 6T lacks a headphone jack and notification
LED.

Current limitations:
  * Bluetooth does not appear in rfkill, this is most likely the reason
    it doesn't appear in UI bluetooth settings, it can be interacted
    with using bluez-utils bluetoothctl.
  * USB is forced to peripheral mode as cable type detection is broken
