[PATCH v1 0/2] arm64: dts: imx8mm-var-som-symphony: minor board updates

[Stefano Radaelli]

This series contains minor updates for the Variscite Symphony carrier
board based on the current hardware configuration.

It updates the RGB_SEL handling and marks the relevant input devices as
wakeup sources.

Stefano Radaelli (2):
  arm64: dts: imx8mm-var-som-symphony: add wakeup sources
  arm64: dts: imx8mm-var-som-symphony: keep RGB_SEL low

[PATCH v1 2/2] arm64: dts: imx8mm-var-som-symphony: keep RGB_SEL low

[Stefano Radaelli]

From: Stefano Radaelli <stefano.r@variscite.com>

Keep the RGB_SEL line driven low on the Symphony carrier board.

This avoids leaving the line floating and ensures the board remains in
the expected display configuration.
