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 ...

spi: Add THIS_MODULE to spi_driver in SPI core

2015-10-28T01:30:12Z

Add spi_register_driver helper macro that adds THIS_MODULE to spi_driver for the registering driver. We rename and modify the existing spi_register_driver to enable this. Signed-off-by: Andrew F. Davis Signed-off-by: Mark Brown

spi: fix kernel-doc warnings about missing return desc in spi.h

2015-10-23T16:28:35Z

When building docs with make htmldocs, warnings about not having a description for the return value are reported, i.e: warning: No description found for return value of 'spi_write' Fix these by following the kernel-doc conventions explained in Documentation/kernel-doc-nano-HOWTO.txt.

ARM: pxa: Remove unused clock_enable field from struct pxa2xx_spi_master

2015-09-20T17:37:20Z

Use for struct pxa2xx_spi_master clock_enable field was removed years ago from the pxa2xx-spi driver by the commit 2f1a74e5a2de ("[ARM] pxa: make pxa2xx_spi driver use ssp_request()/ssp_free()"). Therefore remove it from structure definition, documentation and from couple affected board files. Signed-off-by: Jarkko Nikula Acked-by: Mark Brown Signed-off-by: Robert Jarzmik

spi: bitbang: Replace spinlock by mutex

2015-09-17T11:13:40Z

chipselect (in the case of spi-gpio: spi_gpio_chipselect, which calls gpiod_set_raw_value_cansleep) can sleep, so we should not hold a spinlock while calling it from spi_bitbang_setup. This issue was introduced by this commit, which converted spi-gpio to cansleep variants: d9dda5a191 "spi: spi-gpio: Use 'cansleep' variants to access GPIO" Replacing the lock variable by a mutex fixes the issue: This is safe as all instances where the lock is used are called from contexts that can sleep. Finally, update spi-ppc4xx and and spi-s3c24xx to use mutex functions, as they directly hold the lock for similar purpose. Signed-off-by: Nicolas Boichat Signed-off-by: Mark Brown
