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.
