From ecca1a6277aac10e40e4baba28adb893899b24b3 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 9 Aug 2019 16:40:33 +0200 Subject: net: lpc-enet: move phy setup into platform code 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.
