Merge tag 'omap-for-v3.14/fixes-not-urgent-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/fixes-non-critical
From Tony Lindgren:
Some non-urgent fixes to enable am335x features, update documentation,
and to remove unnecessary double initialization for the GPMC code.
* tag 'omap-for-v3.14/fixes-not-urgent-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (238 commits)
ARM: OMAP2+: gpmc: Move legacy GPMC width setting
ARM: OMAP2+: gpmc: Introduce gpmc_set_legacy()
ARM: OMAP2+: gpmc: Move initialization outside the gpmc_t condition
ARM: OMAP2+: board-generic: update SoC compatibility strings
Documentation: dt: OMAP: explicitly state SoC compatible strings
ARM: OMAP2+: enable AM33xx SOC EVM audio
ARM: OMAP2+: Select USB PHY for AM335x SoC
+Linux 3.13-rc5
