arm64: dts: freescale: Add support for bytesatwork byteDEVKIT i.MX93

This series introduces support for the bytesatwork byteENGINE i.MX93 System on Module (SoM) and the carrier board byteDEVKIT.
It also adds display support for the integrated Youritech et050fw01-kt MIPI-DSI panel by extending the existing ILI9806E panel driver.

Changes in v2:
- Patch 1:
- Use specific panel part number (youritech,et050fw01-kt) instead of generic controller name.
- Elaborate commit message with vendor description, panel resolution and dimensions.
- Patch 2:
- Update compatible string and function names to match youritech,et050fw01-kt.
- Fix commit subject formatting and commit message.
- Patch 3:
- No changes.
- Patch 4:
- Drop standalone SoM compatible entry from fsl.yaml (only bootable board combinations allowed).
- Fix typo in commit message ("byteDEVKIT carrier board").
- Patch 5:
- Update panel compatible string to youritech,et050fw01-kt.
- Invert GT911 GPIO polarity to GPIO_ACTIVE_HIGH to fix address strapping and reset.
- Assign pinctrl_usb2 to reg_usb2_vbus and add vbus-supply to usbotg2.
- Add disable-over-current to usbotg1 and usbotg2.
- Move panel reset GPIO into dedicated pinctrl_panel_reset group on panel@0.
- Standardize Ethernet PHY node names to ethernet-phy@... and use tx-fifo-depth.
- Replace underscores in pinctrl node names with hyphens.
- Rename tca6418e node to generic gpio@34.
- Consolidate devkit devicetrees into single imx93-bytedevkit.dts.

Hi Frank,

Some comments inline.

[...]

Keep in mind that not only mu1 and mu2 activation should be done in the .dts file. I used them just as an example. There lots of other instances in the same situation in the imx93-byteengine.dtsi file.

Also, please use reply-all when answering.

Hi Daniel,

Understood, thanks for pointing that out (and apologies for the missing CCs on my previous reply).

I will remove status = "okay" from all controller nodes in imx93-byteengine.dtsi (&mu1, &mu2, &wdog3, &usdhc1, &lpi2c2) and enable them explicitly in imx93-bytedevkit.dts instead.

This will be reflected in the upcoming v3 series.

Best regards,
Frank
