Merge tag 'omap-for-v3.13/display-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
I accidentally removed some mux code for omap4 that I thought was dead code as omap4 has been booting with device tree only since v3.10. Turns out I also removed some display related mux code, so let's revert that except for the dead code parts. * tag 'omap-for-v3.13/display-fix' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (439 commits) Revert "ARM: OMAP2+: Remove legacy mux code for display.c" +Linux 3.13-rc4
