Subject: [PATCH 07/14] net: lpc-enet: move phy setup into platform code
Date: Wed, 31 Jul 2019 21:56:49 +0200 [thread overview]
Message-ID: <20190731195713.3150463-8-arnd@arndb.de> (raw)
In-Reply-To: <20190731195713.3150463-1-arnd@arndb.de>
Setting the phy mode requires touching a platform specific
register, which prevents us from building the driver without
its header files.
Move it into a separate function in arch/arm/mach/lpc32xx
to hide the core registers from the network driver.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
