Merge tag 'omap-for-v3.7-rc1/fixes-take5-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren: A boot problem fix for am33xx beaglebone caused by GPMC, a regression fix for local timer, and a clockdomain locking fix. Also few minor fixes for boot time and sparse warnings. * tag 'omap-for-v3.7-rc1/fixes-take5-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: Allow kernel to boot even if GPMC fails to reserve memory ARM: OMAP: clockdomain: Fix locking on _clkdm_clk_hwmod_enable / disable ARM: OMAP4: devices: fixup OMAP4 DMIC platform device error message ARM: OMAP2+: clock data: Add dev-id for the omap-gpmc dummy fck ARM: OMAP: resolve sparse warning concerning debug_card_init() ARM: OMAP4: Fix twd_local_timer_register regression
