[PATCH V2 2/2] arm64: dts: imx8mn-beacon: Fix SPI CS pinmux

From: Adam Ford
Date: Sun May 28 2023 - 07:23:21 EST


The final production baseboard had a different chip select than
earlier prototype boards. When the newer board was released,
the SPI stopped working because the wrong pin was used in the device
tree and conflicted with the UART RTS. Fix the pinmux for
production boards.
