+Subject: [PATCH 03/70] MIPS: lantiq: change ltq_request_gpio() call signature
+
+ltq_request_gpio() was using alt0/1 to multiplex the function of GPIO pins.
+This was XWAY specific. In order to also accomodate SoCs that require more bits
+we use a 32bit mask instead. This way the call signature is consistent between
+XWAY and FALC-ON.
