Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson: "Again we have a sizable (but not huge) cleanup branch with a net delta of about -3k lines. Main contents here is: - A bunch of development/cleanup of a few PXA boards - Removal of bockw platforms on shmobile, since the platform has now gone completely multiplatform. Whee! - move of the 32kHz timer on OMAP to a proper timesource - Misc cleanup of older OMAP material (incl removal of one board file) - Switch over to new common PWM lookup support for several platforms There's also a handful of other cleanups across the tree, but the above are the major pieces" * tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (103 commits) ARM: OMAP3: hwmod data: Remove legacy mailbox data and addrs ARM: DRA7: hwmod data: Remove spinlock hwmod addrs ARM: OMAP4: hwmod data: Remove spinlock hwmod addrs ARM: DRA7/AM335x/AM437x: hwmod: Remove gpmc address space from hwmod data ARM: Remove __ref on hotplug cpu die path ARM: Remove open-coded version of IRQCHIP_DECLARE arm: omap2: board-generic: use omap4_local_timer_init for AM437x ARM: DRA7/AM335x/AM437x: hwmod: Remove elm address space from hwmod data ARM: OMAP: Remove duplicated operand in OR operation clocksource: ti-32k: make it depend on GENERIC_CLOCKSOURCE ARM: pxa: remove incorrect __init annotation on pxa27x_set_pwrmode ARM: pxa: raumfeld: make some variables static ARM: OMAP: Change all cpu_is_* occurences to soc_is_* for id.c ARM: OMAP2+: Rename cpu_is macros to soc_is arm: omap2: timer: limit hwmod usage to non-DT boots arm: omap2+: select 32k clocksource driver clocksource: add TI 32.768 Hz counter driver arm: omap2: timer: rename omap_sync32k_timer_init() arm: omap2: timer: always call clocksource_of_init() when DT arm: omap2: timer: move realtime_counter_init() around ...
