Subject: [PATCH 23/36] ARM: s3c: move s3cmci pinctrl handling into board files
Date: Thu, 10 Oct 2019 22:30:07 +0200 [thread overview]
Message-ID: <20191010203043.1241612-23-arnd@arndb.de> (raw)
In-Reply-To: <20191010203043.1241612-1-arnd@arndb.de>
Rather than call the internal s3c_gpio_cfgall_range() function
through a platform header, move the code into the set_power
callback that is already exported by the board, and add
a default implementation.
In DT mode, the code already does not set the pin config,
so nothing changes there.
