From: Johan Hovold Date: Wed, 19 Nov 2014 11:59:15 +0000 (+0100) Subject: net: phy: micrel: add device-type abstraction X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e6a423a81da0eb3da755428f4d2df5a9ba13030f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git net: phy: micrel: add device-type abstraction Add structured device-type information and support for generic led-mode setup to the generic config_init callback. This is a first step in ultimately getting rid of device-type specific callbacks. Signed-off-by: Johan Hovold Signed-off-by: David S.
