4 Subject: [PATCH] MIPS: ralink: Add rt3352 SPI_CS1 pinmux
5
6 The rt3352 has a pin that can be used as second spi chip select,
7 watchdog reset or GPIO. The pinmux setup was missing the definition of
8 said pin.
9
10 The pin is configured via the same bit on rt5350, so reuse the existing
11 macro.
