[PATCH 0/7] arm64: dts: qcom: Add 3 new devices

[Adam Skladowski]

Introduce support for 3 new devices:
- Motorola Moto One based on MSM8953
- LeEco Le2 based on MSM8976
- Xiaomi Redmi 9T based on SM6115

Device trees besides enabling most of supported hardware also wires power to
subsystems like MDSS even if those are not enabled to lower maintenance burden
on out of tree forks.

[PATCH 3/7] arm64: dts: qcom: Add Motorola One

[Adam Skladowski]

Add a devicetree for the Motorola One smartphone, which is based
on the Jacala/MSM8953 SoC.

Supported functionality as of this initial submission:
* I2C peripherals (Touchscreen,NFC)
* Power Button, Volume Keys
* Regulators (PM8953)
* Remoteprocs (ADSP, MPSS, WCNSS)
* USB

Device tree also contains supply maps to other subsystems like MDSS
but due to missing dependencies like panel those are disabled.

Why are the bus and this chip disabled?

Preferably one a line with a best-effort set of comments describing
what these pins correspond to (see glymur-crd.dtsi)

Drop output-foo from TLMM pins, the consumer driver should set the output
state via the GPIO APIs

Best regards,

[PATCH 5/7] arm64: dts: qcom: Add LeEco Le2

[Adam Skladowski]

Add a devicetree for the LeEco Le2 smartphone, which is based
on the Eldarion/MSM8976 SoC.

Supported functionality as of this initial submission:
* I2C peripherals (Touchscreen,Audio amp, Haptics, Extcon, Led)
* Power Button, Volume Keys
* Regulators (PM8950)
* WLED (PMI8950)
* Remoteprocs (WCNSS)
* GPU

Device tree also contains supply maps to other subsystems like MDSS
but due to missing dependencies like panel those are disabled.

Referring to nodes by their node names is fragile. In this case, you fell
victim to that since this node doesn't exist. The more modern approach is
to assign a label at the definition site and then do /delete-node/ &foo

Let's keep a \n between properties and the following subnodes

The second extcon is optional, you can drop it

from the chipidea bindings:

[PATCH 7/7] arm64: dts: qcom: Add Xiaomi Redmi 9T

[Adam Skladowski]

Add a devicetree for the Xiaomi Redmi 9T smartphone, which is based
on the Bengal/SM6115 SoC.

Supported functionality as of this initial submission:

* Display via SimpleFB/SimpleDRM
* GPU
* I2C peripherals (Backlight)
* Power Button, Volume Keys
* Regulators
* Remoteprocs (ADSP, CDSP, MPSS)
* UFS/SDCARD
* USB

Device tree also contains supply maps to other subsystems like MDSS
but due to missing dependencies like panel those are disabled.
