[PATCH v9 0/8] arm64: dts: add description for solidrun imx8mp hummingboard-iiot

This patchset mainly adds description for 3 SolidRun boards:
- i.MX8MP Hummingboard IIoT
- SolidSense N8 Compact
- i.MX8MM Hummingboard Ripple

This includes dt bindings and a range of bug-fixes:

- dt bindings for the boards
- fix to dsi panel bindings referencing panel-common and adding port
  property
- cosmetic fix to some  solidrun imx8mp boards for regulator gpio
   polarity
- fix dsi hdmi bridge on hummingboard pulse
- compile dtbs with symbols to support overlays
- gpiod_set_value _can_sleep conversion for panel and touchscreen
   drivers

Open Questions:

- How to describe HX3 USB-2.0/3.0 Hub placed on a USB-2.0-only Bus
  (affects imx8mm-hummingboard-ripple.dts)
- Is "description for" implied not only on dt-bindings patches, but also
  dts? E.g. is this commit subject acceptable?:
  "arm64: dts: add solidrun solidsense-n8 board"
