[PATCH v3 10/14] arm64: dts: imx8mp-var-som-symphony: keep RGB_SEL low

From: Stefano Radaelli

Date: Wed Jun 03 2026 - 11:17:04 EST


From: Stefano Radaelli <stefano.r@xxxxxxxxxxxxx>

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.
