Subject: [PATCH 21/46] ARM: pxa: spitz: use gpio descriptors for audio
Date: Fri, 18 Oct 2019 17:41:36 +0200 [thread overview]
Message-ID: <20191018154201.1276638-21-arnd@arndb.de> (raw)
In-Reply-To: <20191018154052.1276506-1-arnd@arndb.de>
The audio driver should not use a hardwired gpio number
from the header. Change it to use a lookup table.
