[PATCH v7 1/5] arm64: dts: freescale: imx8mp: fix sort order

[Steffen Trumtrar]

The imx8mp-skov-revc-jutouch should be alphabetically before the
imx8mp-skov-revc-tian variant.

Sort the entries in the correct order.

[PATCH v7 3/5] arm64: dts: imx8mp-skov-revc: convert to overlays

[Steffen Trumtrar]

The i.MX8MP Skov RevC jutouch 10" and Tian 7" variants are pretty
similar, apart from the Display and touch controller.

Move the common bindings to imx8mp-skov-revc-touch.dts and convert both
variants to use overlays applied on this base version.

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 3 potential issue(s) to consider:
- [High] Missing device tree binding includes causes build failure.
- [High] Incorrect touchscreen resolution properties (copy-paste logic error).
- [Medium] Missing #address-cells and #size-cells in &i2c2 node causes compilation warnings.

commit 5301893644854d4544c31ab94b72a17eda53338e
Author: Steffen Trumtrar <s.trumtrar@pengutronix.de>

arm64: dts: imx8mp-skov: support new 7inch panel board
    
This board is similar to the already upstream
imx8mp-skov-revc-tian-g07017 and imx8mp-skov-revc-jt101tm023 but uses a
different 7" panel with a different touch controller.

[Severity: High]
Does this overlay need dt-bindings includes? The C preprocessor won't expand
IRQ_TYPE_LEVEL_LOW and GPIO_ACTIVE_LOW without
<dt-bindings/interrupt-controller/irq.h> and <dt-bindings/gpio/gpio.h>,
which will cause a syntax error during device tree compilation.

[Severity: Medium]
Will this parent node cause dtc warnings during overlay compilation? Since
overlays are compiled in isolation, dtc will fall back to default
#address-cells and #size-cells values, which conflict with the 1-cell reg
property of the child node. Should it explicitly define #address-cells = <1>;
and #size-cells = <0>;?

[Severity: High]
Are these resolution properties correct for this panel? The jutouch,jt070tm041
7" panel has a native resolution of 1024x600. Setting the maximums to 1280x800
will cause miscalibration in userspace, where the touch pointer won't be able
to reach the edges of the screen.
