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 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.

[PATCH 1/5] drm/panel/samsung-sofef00: Add panel for OnePlus 6/T devices

[Caleb Connolly]

The OnePlus 6/T devices use different panels however they are
functionally identical with the only differences being the resolution.
The panels also don't seem to be used by any other devices, just combine
them into one driver.

The panels are: samsung,sofef00
and             samsung,s6e3fc2x01

Changes since v1:
 * Rename driver to samsung-sofef00 rather than be device
 specific.
 * Make use of drm_panel backlight, simplifying the driver.
 * Make reset function do a full reset, instead of simply taking the
 panel out of reset.
 * Removed get_brightness function as it doesn't return correct data.

Thanks, applied to drm-misc-next.
Fixed a few checkpatch --strict warnings when applying.
Please check with --strict in the future.

Thansk, applied to drm-misc-next.
Fixed so entries are sorted alphabetically when applying.

[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:

* Display panels and Adreno 630
* Touch screen support with synaptics rmi4
* All remoteprocs start correctly
* WLAN / Bluetooth
* Volume / power buttons and OnePlus Tri-State switch are functional
    The tri-state switch is a 3 state mute slider on the side of the
    phone
* USB support, currently forced to peripheral as type C detection isn't
functional.

Support for this device depends on the following series:
https://lore.kernel.org/linux-iommu/20201017043907.2656013-1-bjorn.andersson@linaro.org/

Changes since v1
 * Remove unused pinctrl nodes
 * Properly model touchscreen vio supply GPIO
 * Improve comments
 * Remove bq27541 battery as it doesn't work

I have similar switches on my joystick... but I don't believe modelling it as 3 separate
keys with "macro" keysym is the right way to go.

Hi! I agree that this is a bit of a weird way to model the switch, do 
you have any ideas for a better solution?

I'm happy to drop this from the patch for now and come up with a better 
method down the line.

Caleb

You should ask on the input mailing list, I guess.

To avoid trouble finding your way around this file in the future I would
prefer if you sorted the nodes alphabetically.

There should be a sdm845 fallback compatible. Also, board level 
compatibles are documented in a per SoC family schema (qcom.yaml) which 
should already define the fallback.

With a SoC fallback, having this as a 3rd compatible probably isn't too 
useful. 3 levels of compatible is mainly done when there's a SoM plus 
baseboard.

[PATCH 5/5] i2c: geni: sdm845: dont perform DMA for OnePlus 6 devices

[Caleb Connolly]

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

This hack seems to have been working around two separate issues. First
with iommu active the GENI wrappers needs to have their stream mapping
configured. Secondly there was a bug in the transaction setup that was
recently fixed by Doug Anderson.

So can you please give the following patch a go? I've yet to test it on
the Lenovo machine, but I think it allows us to remove the quirk.

Hi Bjorn,

It looks like I still have the same issue even with this patch applied.

Please don't top-post. I fixed it this time.

So we still need your patch, am I reading correctly?

With Doug's recent fixes in the DMA handling and the introduction of
proper iommu configuration, which Caleb tested [1], I think we're good
without this on the OnePlus. Caleb, please confirm.

If I understood Caleb's report he saw exactly the same problem that Lee
Jones did that lead to the workaround for the Lenovo Yoga C630, and with
the two changes the i2c-hid keyboard came up nicely on my Yoga. So I
posted [2].

Yes, he confirmed already. I missed it was private only.

Thanks for your heads up, too!

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.

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 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 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.

2.28.0

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 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.
