Merge tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "A series of fixes (and in some cases, some cleanups): Via Tony Lindgren: - A collection of OMAP regression fixes, in particular because firmware no longer sets up all pin states before starting the kernel. - cpufreq fixes for OMAP (Rafael is on vacation and this was pre-agreed). - A longer series of misc regression fixes and cleanups, warning removals, etc for OMAP From Arnd Bergmann: - A series of warning fixes for various platforms (defconfig builds) Misc: - A couple of tegra fixes, one for i.MX, some vt8500 fixes, etc." * tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (73 commits) ARM: pxa: armcore: fix PCI PIO warnings ARM: integrator: use __iomem pointers for MMIO, part 2 ARM: assabet: fix bogus warning in get_assabet_scr (again) ARM: shmobile: mark shmobile_init_late as __init ARM: integrator_cp: fix build failure ARM: OMAP4/AM335x: hwmod: fix disable_module regression in hardreset handling ARM: OMAP3: fix workaround for EMU clockdomain arm/omap: Replace board_ref_clock with enum values ARM: OMAP2+: remove duplicated include from board-omap3stalker.c arch/arm/plat-omap/omap-pm-noop.c: Remove unecessary semicolon arch/arm/mach-omap2: Remove unecessary semicolon arch/arm/mach-omap1/devices.c: Remove unecessary semicolon ARM/dts: omap5-evm: pinmux configuration for audio ARM/dts: Add pinctrl driver entries for omap5 ARM/dts: omap4-panda: pinmux configuration for audio ARM/dts: omap4-sdp: pinmux configuration for audio ARM/dts: omap5-evm: Disable unused McBSP3 ARM/dts: omap4-sdp: Disable unused McBSP3 ARM/dts: omap4-panda: Disable unused audio IPs ARM: OMAP: board-omap4panda: Pin mux configuration for audio needs ...
