Subject: [PATCH 18/36] ARM: s3c: gta02-audio: turn into platform driver
Date: Thu, 10 Oct 2019 22:30:02 +0200 [thread overview]
Message-ID: <20191010203043.1241612-18-arnd@arndb.de> (raw)
In-Reply-To: <20191010203043.1241612-1-arnd@arndb.de>
Avoid machine specific headers by using a gpio lookup table
combined with a platform_driver for this board.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
