[PATCH 0/3] Add Xiaomi Poco F1 touchscreen support

[PATCH 0/3] Add Xiaomi Poco F1 touchscreen support

[Joel Selvaraj via B4 Relay]

In the first patch, I have enabled the  qupv3_id_1 and gpi_dma1 as they 
are required for configuring touchscreen. Also added the pinctrl configurations.
These are common for both the Poco F1 Tianma and EBBG panel variant.

In the subsequent patches, I have enabled support for the Novatek NT36672a
touchscreen and FocalTech FT8719 touchscreen that are used in the Poco F1
Tianma and EBBG panel variant respectively.

[PATCH 1/3] arm64: dts: qcom: sdm845-xiaomi-beryllium-common: add touchscreen related nodes

[Joel Selvaraj via B4 Relay]

From: Joel Selvaraj <joelselvaraj.oss@gmail.com>

Enable qupv3_id_1 and gpi_dma1 as they are required for configuring
touchscreen. Also add pinctrl configurations needed for touchscreen.
These are common for both the tianma and ebbg touchscreen variant.
In the subsequent patches, we will enable support for the Novatek NT36672a
touchscreen and FocalTech FT8719 touchscreen that are used in the Poco F1
Tianma and EBBG panel variant respectively. This is done in preparation
for that.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

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

  pip3 install dtschema --upgrade

This needs a bindings update

I think these warnings are unhappy about input-enable (which is not really a
thing on TLMM, see:

e49eabe3e13f ("pinctrl: qcom: Support OUTPUT_ENABLE; deprecate INPUT_ENABLE")
