From 2f361e9459559d4ea97f6645ea6d2f814fb5f2e9 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 11 Sep 2019 13:57:45 +0200 Subject: [PATCH] ARM: pxa: corgi: 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.
