Merge tag 'omap-for-v3.8/fixes-for-merge-window-v4-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

From Tony Lindgren:

These patches fixes a build error caused by a merge
conflict with the fb code, few timer warnings, and longer
term regressions for tfp410 and omap h4 ethernet. Also
included is a GPIO mode fix for the legacy mux code.
