…/git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes

From Tony Lindgren:
Few more fixes for issues found booting older omaps using device tree.
Also few randconfig build fixes and removal of some dead code for omap4
as it no longer has legacy platform data based booting support.

* tag 'omap-for-v3.13/more-fixes-for-merge-window-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP2+: Remove legacy omap4_twl6030_hsmmc_init
  ARM: OMAP2+: Remove legacy mux code for display.c
  ARM: OMAP2+: Fix undefined reference to set_cntfreq
  gpio: twl4030: Fix passing of pdata in the device tree case
  gpio: twl4030: Fix regression for twl gpio output
  ARM: OMAP2+: More randconfig fixes for reconfigure_io_chain
  ARM: dts: Fix omap2 specific dtsi files by adding the missing entries
  ARM: OMAP2+: Fix GPMC and simplify bootloader timings for 8250 and smc91x
  i2c: omap: Fix missing device tree flags for omap2
