[PATCH v1 0/7] Add support for various features to i.MX6 bindings

[PATCH v1 0/7] Add support for various features to i.MX6 bindings

[Oleksij Rempel]

changes v2:
- fix warning samples in the commit messages
- drop patches which needs more work
- address requested changes 

This patch series is aimed at addressing several dtbs_check warnings by
introducing additional support in the device tree bindings for i.MX6
series SoCs. The warnings surfaced while validating some i.MX6 boards.
The issues were predominantly around unrecognized compatibility strings
and missing properties in the device trees.

Oleksij Rempel (5):
  dt-bindings: mmc: fsl-imx-esdhc: Add imx6ul support
  dt-bindings: timer: gpt: Add i.MX6UL support
  dt-bindings: timer: gpt: Support 3rd clock for i.MX6DL
  dt-bindings: clock: imx6ul: Support optional enet*_ref_pad clocks
  dt-bindings: input: touchscreen: edt-ft5x06: Add 'threshold' property

[PATCH v2 1/5] dt-bindings: mmc: fsl-imx-esdhc: Add imx6ul support

[Oleksij Rempel]

Add the 'fsl,imx6ul-usdhc' value to the compatible properties list in
the fsl-imx-esdhc.yaml file. This is required to match the compatible
strings present in the 'mmc@2190000' node of 'imx6ul-prti6g.dtb'. This
commit addresses the following dtbs_check warning:
imx6ul-prti6g.dtb:0:0: /soc/bus@2100000/mmc@2190000: failed to match any schema with compatible: ['fsl,imx6ul-usdhc', 'fsl,imx6sx-usdhc']

[Oleksij Rempel]

[PATCH v2 5/5] dt-bindings: input: touchscreen: edt-ft5x06: Add 'threshold' property

[Oleksij Rempel]

Add a new property 'threshold' to the edt-ft5x06 touchscreen binding.
This property allows setting the "click"-threshold in the range from 0
to 255. This change addresses the following dtbs_check warning:
imx6dl-lanmcu.dtb: touchscreen@38: 'threshold' does not match any of the regexes: 'pinctrl-[0-9]+'

Hey Oleksij,

hmm, "imx6ull-jozacp" but the compatible is "imx6ul-gpt".
Is that not incorrect in the first place?

Also, this diff has already made it in - it is in next as 451d69d2f1f9
("dt-bindings: imxgpt: add imx6ul compatible"), applied on 20.05.2023
or similar.

Cheers,
Conor.
