Add support for the OnePlus 6 and 6T SDM845 devices

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

[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

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

[Sam Ravnborg]

Hi Caleb.

I have missed to provice review feedback so here goes.
There is some improvements that can be made as the infrastructure has
evolved since the driver was started.
But despite the number of comments below it is all trivial and the
driver looks good in general.

I look forward to see the next revision.

	Sam

It would be better to name the driver after the panels and not their
user. So something like panel-samsung-sofef00.
It is OK to name it after one panel and let it support mroe than one
panel. The Kconfig description could then expain where it is used.

Use drm_panel backlight support - so you can drop this variable and

IT is not obvious if this helper reset the panel or de-assert the reset
signal. It does not help me that there is only one helper despite both
operatiosn are needed.

Do you not need to do a regulator_enable() here to get power supply to
the panel?

Looks strange that the power supply is enabled here - was it not enabled
before to use the panel?

When backlight support in drm_panel is used the two enabled/disable
functions can be dropped and the enabled flag is then no longer sued and
can be dropped too.

Some indent looks fishy here.

No need to read the brightness here. It will be set if

Use backlight_get_brightness() to get the current brightness from the

Hi Sam,

Thanks a lot for the feedback! I'll get those issues resolved for the 
next revision.

My bot found errors running 'make dt_binding_check' on your patch:

Error: Documentation/devicetree/bindings/display/panel/panel-oneplus6.example.dts:19.9-14 syntax error
FATAL ERROR: Unable to parse input tree

See https://patchwork.ozlabs.org/patch/1378187

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.

[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.
