From: Dasnavis Sabiya <sabiya.d@xxxxxx> Add pinmux required to bring out the i2c and gpios on 40 pin RPi expansion header on AM69 SK board. Signed-off-by: Dasnavis Sabiya <sabiya.d@xxxxxx> Signed-off-by: Nishanth Menon <nm@xxxxxx> --- Depends on https://lore.kernel.org/linux-arm-kernel/20230503083143.32369-1-t-konduru@xxxxxx/ Changes since V1: * Rebased on the pinmux split up done from the dependency. * Some minor style fixups.
