From e6c91e1adfd385e99cbe5d1b90684ebeb96540ea Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 11 Sep 2019 14:27:13 +0200 Subject: [PATCH] ARM: pxa: hx4700: use gpio descriptors for audio The audio driver should not use a hardwired gpio number from the header. Change it to use a lookup table.
