Merge tag 'omap-for-v3.11/fixes-for-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Omap fixes and minor defconfig updates that would be good to get in before -rc1. * tag 'omap-for-v3.11/fixes-for-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: omap2plus_defconfig: Enable appended DTB support ARM: OMAP2+: Enable TI_EDMA in omap2plus_defconfig ARM: OMAP2+: omap2plus_defconfig: enable DRA752 thermal support by default ARM: OMAP2+: omap2plus_defconfig: enable TI bandgap driver ARM: OMAP2+: devices: remove duplicated include from devices.c ARM: OMAP3: igep0020: Set DSS pins in correct mux mode. ARM: OMAP2+: N900: enable N900-specific drivers even if device tree is enabled ARM: OMAP2+: Cocci spatch "ptr_ret.spatch" ARM: OMAP2+: Remove obsolete Makefile line ARM: OMAP5: Enable Cortex A15 errata 798181 ARM: scu: provide inline dummy functions when SCU is not present ARM: OMAP4: sleep: build OMAP4 specific functions only for OMAP4 ARM: OMAP2+: timer: initialize before using oh_name Signed-off-by: Olof Johansson <olof@lixom.net> Add/move/change conflicts in arch/arm/mach-omap2/Kconfig resolved.
