+Subject: [PATCH] MIPS: ralink: Fix mt7620 nd_sd pinmux
+
+In case the nd_sd group is set to the sd-card function, Pins 45 + 46 are
+configured as GPIOs. If they are blocked by the sd function, they can't
+be used as GPIOs.

+Fixes: f576fb6a0700 ("MIPS: ralink: cleanup the soc specific pinmux
+data")
