| | * | mfd: ab8500-debugfs: Dump sim registersLee Jones2013-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows to dump the SIM registers from debugfs. It will temporary change the config to allow APE side to read the SIM registers. Note that this read can cause problem on modem side since the modem can't read these registers while the operation is ongoing.

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 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both OMAP4 and 5 exhibit the same revision ID in the REVISION register but they have different number of ports i.e. 2 and 3 respectively.
