mfd: twl4030-madc: Remove __exit_p annotation

2013-03-15T06:42:22Z

4740f73fe5 "mfd: remove use of __devexit" removed the __devexit annotation on the twl4030_madc_remove function, but left an __exit_p() present on the pointer to this function. Using __exit_p was as wrong with the devexit in place as it is now, but now we get a gcc warning about an unused function. In order for the twl4030_madc_remove to work correctly in built-in code, we have to remove the __exit_p.

mfd: ab8500-gpadc: Complain if we fail to enable vtvout LDO

2013-03-12T08:34:39Z

Since commit c8801a8e "regulator: core: Mark all get and enable calls as __must_check", we must check return value of regulator_enable() to silence below build warning. CC drivers/mfd/ab8500-gpadc.o drivers/mfd/ab8500-gpadc.c: In function 'ab8500_gpadc_runtime_resume': drivers/mfd/ab8500-gpadc.c:598:18: warning: ignoring return value of 'regulator_enable', declared with attribute warn_unused_result [-Wunused-result] drivers/mfd/ab8500-gpadc.c: In function 'ab8500_gpadc_probe': drivers/mfd/ab8500-gpadc.c:655:18: warning: ignoring return value of 'regulator_enable', declared with attribute warn_unused_result [-Wunused-result] Also convert to devm_regulator_get(), this fixes a missing regulator_put() call in ab8500_gpadc_remove().

mfd: twl4030-audio: Fix argument type for twl4030_audio_disable_resource()

2013-03-12T08:25:51Z

Looks like the conversion to enum was missed for the definition of this function, the declaration has been updated. Signed-off-by: Mark Brown Acked-by: Peter Ujfalusi Signed-off-by: Samuel Ortiz

mfd: tps65912: Declare and use tps65912_irq_exit()

2013-03-12T08:25:50Z

Clean up interrupts on exit, silencing a sparse warning caused by tps65912_irq_exit() being defined but not prototyped as we go. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

mfd: palmas: Provide irq flags through DT/platform data

2013-03-12T08:25:49Z

Currently driver sets the irq type to IRQF_TRIGGER_LOW which is causing interrupt registration failure in ARM based SoCs as: [ 0.208479] genirq: Setting trigger mode 8 for irq 118 failed (gic_set_type+0x0/0xf0) [ 0.208513] dummy 0-0059: Failed to request IRQ 118: -22 Provide the irq flags through platform data if device is registered through board file or get the irq type from DT node property in place of hardcoding the irq flag in driver to support multiple platforms. Also configure the device to generate the interrupt signal according to flag type. Signed-off-by: Laxman Dewangan Signed-off-by: Samuel Ortiz

mfd: omap-usb-host: Actually update hostconfig

2013-03-12T08:07:27Z

Pull MFS updates from Samuel Ortiz: "This is the MFD pull request for the 3.9 merge window. No new drivers this time, but a bunch of fairly big cleanups: - Roger Quadros worked on a OMAP USBHS and TLL platform data consolidation, OMAP5 support and clock management code cleanup. - The first step of a major sync for the ab8500 driver from Lee Jones. In particular, the debugfs and the sysct interfaces got extended and improved. - Peter Ujfalusi sent a nice patchset for cleaning and fixing the twl-core driver, with a much needed module id lookup code improvement. - The regular wm5102 and arizona cleanups and fixes from Mark Brown. - Laxman Dewangan extended the palmas APIs in order to implement the palmas GPIO and rt drivers. - Laxman also added DT support for the tps65090 driver. - The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra and Darren Hart. - Linus Walleij patchset for the ab8500 driver allowed ab8500 and ab9540 based devices to switch to the new abx500 pin-ctrl driver. - The max8925 now has device tree and irqdomain support thanks to Qing Xu. - The recently added rtsx driver got a few cleanups and fixes for a better card detection code path and now also supports the RTS5227 chipset, thanks to Wei Wang and Roger Tseng." * tag 'mfd-3.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (109 commits) mfd: lpc_ich: Use devres API to allocate private data mfd: lpc_ich: Add Device IDs for Intel Wellsburg PCH mfd: lpc_sch: Accomodate partial population of the MFD devices mfd: da9052-i2c: Staticize da9052_i2c_fix() mfd: syscon: Fix sparse warning mfd: twl-core: Fix kernel panic on boot mfd: rtsx: Fix issue that booting OS with SD card inserted mfd: ab8500: Fix compile error mfd: Add missing GENERIC_HARDIRQS dependecies Documentation: Add docs for max8925 dt mfd: max8925: Add dts mfd: max8925: Support dt for backlight mfd: max8925: Fix onkey driver irq base mfd: max8925: Fix mfd device register failure mfd: max8925: Add irqdomain for dt mfd: vexpress: Allow vexpress-sysreg to self-initialise mfd: rtsx: Support RTS5227 mfd: rtsx: Implement driving adjustment to device-dependent callbacks mfd: vexpress: Add pseudo-GPIO based LEDs mfd: ab8500: Rename ab8500 to abx500 for hwmon driver ...
