[PATCH v2 0/6] arm64: dts: imx8mp-skov: add new variants

[Ahmad Fatoum]

The Skov i.MX8MP boards are a family of climate controllers.

There are already device trees for three board variants and this series
adds support for three more:

- Basic: Barebones DT for use as bootloader device tree and as fallback
    when a device is unknown
  - BD500: No touch screen, but a few LEDs on the front plate
  - TIAN G07017: with a 7" touch screen

---
Changes in v2:
- Added Conor's Acked-by (Thanks!)
- Fix comment typo in binding document
- Rebased on top of Shawn's for-next to resolve a trivial conflict
  around the RTC I2C frequency
- Link to v1: https://lore.kernel.org/r/20250113-skov-imx8mp-new-boards-v1-0-75288def1271@pengutronix.de

[PATCH v2 1/6] dt-bindings: arm: fsl: add more compatibles for Skov i.MX8MP variants

[Ahmad Fatoum]

The Skov i.MX8MP boards are a family of climate controllers.

In preparation for adding device trees for three more variants,
describe their DT compatible in the bindings.

[PATCH v2 2/6] arm64: dts: imx8mp-skov: add basic board as fallback

[Ahmad Fatoum]

From: Oleksij Rempel <o.rempel@pengutronix.de>

All Skov i.MX8MP boards share the same baseboard (modulo revisions)
and are booted with the same bootloader image, which samples some
strapping pins at startup and determines which kernel device tree
to use.

For use as bootloader device tree and as fallback, when no matching
device tree has been found, add a basic variant that doesn't configure
any variant-specific peripherals like displays.

[PATCH v2 3/6] arm64: dts: imx8mp-skov: move I2C2 pin control group into DTSI

[Ahmad Fatoum]

I2C2 is exposed on a pin header on the base board, so its pinmux is
always the same if it's enabled.

Therefore, move the definition to the common DTSI, so board DTs only
need to override the status to enable it.

[PATCH v2 4/6] arm64: dts: imx8mp-skov: describe I2C bus recovery for all controllers

[Ahmad Fatoum]

I2C bus recovery can be used to recover when SCL/SDA are stuck low.
To be able to use it, add the necessary GPIO and pinctrl entries.

[PATCH v2 6/6] arm64: dts: imx8mp-skov: support new 7" panel board

[Ahmad Fatoum]

This board is very similar to the already upstream
imx8mp-skov-revb-mi1010ait-1cp1.dts with the difference that it uses a
different 7" LVDS panel.

Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de>
---
Note: The panel's binding is already in linux-next.
