[PATCH 1/4] arm64: dts: ti: k3-am62x-phyboard-lyra: Set RGB input to 16-bit for HDMI bridge

[Wadim Egorov]

The phyBOARD-Lyra connects only 16 pins to the SII902x HDMI bridge's RGB
input. The default 24-bit setting causes incorrect color output. Update
to 16-bit to match the hardware configuration.

[PATCH 2/4] arm64: dts: ti: k3-am62x-phyboard-lyra: Add HDMI bridge regulators

[Wadim Egorov]

Specify I/0 voltage & core supply regulators used by the SII902x
HDMI bridge and make them known to the bridge.
This resolves the following warning:

  sii902x 1-0039: supply iovcc not found, using dummy regulator
  sii902x 1-0039: supply cvcc12 not found, using dummy regulator

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
