[PATCH 1/8] ARM: dts: imx51-zii-rdu1: rename node name i2c-gpio to i2c-0

[Frank.Li]

From: Frank Li <Frank.Li@nxp.com>

The binding expects the node name to match the pattern
'^i2c(@.+|-[a-z0-9]+)?$', but the node was named 'i2c-gpio' which conflicts
with schema validation and produces:

arch/arm/boot/dts/nxp/imx/imx51-zii-rdu1.dtb: / (zii,imx51-rdu1): i2c-gpio: {'compatible': ['i2c-gpio'], 'pinctrl-names': ['default'], 'pinctrl-0': [[47]], 'sda-gpios': [[17, 2, 0]], 'scl-gpios': [[31, 4, 0]], 'i2c-gpio,delay-us': [50], 'status': ['okay'], '#address-cells': 1, '#size-cells': 0, 'codec@a': {'compatible': ['fsl,sgtl5000'], 'reg': [[10]], 'clocks': [[48]], 'VDDA-supply': [[49]], 'VDDIO-supply': [[50]], '#sound-dai-cells': 0, 'phandle': 57}} is not of type 'array'

Rename the node to 'i2c-0' to fix above dtbs_check warning.

[PATCH 2/8] ARM: dts: imx6qdl-emcon: Remove unrecognized disable-gpio PCIe property

[Frank.Li]

From: Frank Li <Frank.Li@nxp.com>

The 'disable-gpio' property is not defined in the fsl,imx6q-pcie
binding schema and driver code, which causes the following dtbs_check
warning:

From: Frank Li <Frank.Li@nxp.com>

Remove undocumented and used property wakeup-gpios, which is the same
as interrupts-extended.

Fix below check_dtbs warning:

[PATCH 4/8] ARM: dts: imx7d-meerkat96: disable lcdif node

[Frank.Li]

From: Frank Li <Frank.Li@nxp.com>

The LCDIF node is enabled, but no display panel is connected through the
required graph bindings. As a result, the LCDIF DT description is
incomplete and triggers DT schema validation warnings.

 arch/arm/boot/dts/nxp/imx/imx7d-meerkat96.dtb: lcdif@30730000 (fsl,imx7d-lcdif): 'port' is a required propert

Disable the LCDIF node until a proper panel node and display pipeline are
added to fix above warnings.

[PATCH 5/8] ARM: dts: imx50-kobo-aura: convert sd2_vmmc to regulator-fixed

[Frank.Li]

From: Frank Li <Frank.Li@nxp.com>

The sd2_vmmc regulator was using compatible = "regulator-gpio" with
only a single state entry (states = <3300000 0>), which violates the
gpio-regulator DT schema that requires at least two state pairs.

Since the regulator operates at a fixed 3.3 V (regulator-min-microvolt
equals regulator-max-microvolt), convert the node to regulator-fixed.

Fix below check_dtbs warnings:
  arch/arm/boot/dts/nxp/imx/imx50-kobo-aura.dtb: gpio-regulator (regulator-gpio): states: [[3300000, 0]] is too short

[PATCH 6/8] ARM: dts: imx6dl-b125v2: add touchscreen-size-x/y to exc80h60 node

[Frank.Li]

From: Frank Li <Frank.Li@nxp.com>

The eeti,exc3000 binding requires touchscreen-size-x and
touchscreen-size-y properties. Add them for both the B125v2 and B125Pv2
boards, which use the AUO G121EAN01 panel at 1280x800 resolution.
