The rt3352 has a pin that can be used as second spi chip select, watchdog reset or GPIO. The pinmux setup was missing the definition of said pin but it is already used in the SoC dtsi. Signed-off-by: Mathias Kresin <dev@kresin.me>

Subject: [PATCH] MIPS: ralink: Add rt3352 SPI_CS1 pinmux
|
|
|
|
The rt3352 has a pin that can be used as second spi chip select,
|
|
watchdog reset or GPIO. The pinmux setup was missing the definition of
|
|
said pin.
|
|
|
|
The pin is configured via the same bit on rt5350, so reuse the existing
|
|
macro.
