Subject: [PATCH 22/36] ARM: s3c: leds: move setpull() calls into board files
Date:   Thu, 10 Oct 2019 22:30:06 +0200
Message-Id: <20191010203043.1241612-22-arnd@arndb.de>
In-Reply-To: <20191010203043.1241612-1-arnd@arndb.de>

Precedence: bulk

The leds-s3c24xx driver calls the private s3c_gpio_setpull()
interface for each gpio line, but doing this requires
access to the machine header files.

Move those calls into the machine init functions for any
board that uses the driver.
