From 9a97434215819872b054c3d0c067e5e4fa768b0e Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Mon, 17 Oct 2016 21:45:29 +0200 Subject: [PATCH] ARM: pxa: enhance smc91x platform data Instead of having the smc91x driver relying on machine_is_*() calls, provide this data through platform data, ie. idp, mainstone and stargate. This way, the driver doesn't need anymore machine_is_*() calls, which wouldn't work anymore with a device-tree build. Signed-off-by: Robert Jarzmik Signed-off-by: David S.
