[PATCH v2 02/16] ARM: dts: imx6qdl: SolidRun: move AR8035 into microsom

Russell King rmk+kernel at armlinux.org.uk
Tue Nov 28 07:02:05 PST 2017


As all SolidRun microsoms are fitted with an AR8035, it's pointless
having the ethernet support as a separate include file.  Move the
AR8035 support into the main imx6qdl-microsom file.
