mfd: dbx500/abx500: root out hardcoded IRQ assignments

2014-03-04T00:58:11+00:00

The DBx500 and ABx500 should be getting their IRQs from the device tree and nowhere else. Get rid of all the static assignments everywhere, delete it from the driver, platform data and the board files in one swift strike. Lots of cross-dependencies in the MFD drivers for PRCMU and AB8500 makes it necessary to strike everywhere at once to eradicate IRQs passed as resources and platform data to the left and right around the platform.

mfd: dbx500-prcmu: Move PRCMU numerical clock identifiers into DT include file

2013-09-26T09:04:12+00:00

These are required to request DBx500 PRCMU clocks from Device Tree. The numbers used are taken directly from the Hardware Specification document. We're moving them from the DBx500 PRCMU include file into the DT include directory and referencing them from the former via a #include.

ARM: ux500: split out prcmu initialization

2013-04-08T11:58:15+00:00

This untangles the final bits of the prcmu code from the platform code: * The IRQ_PRCMU_* definitions move from irqs-db8500.h into prcmu.c because they are only of local significance. * u8500_thsens_device goes into the prcmu, because it uses a PRCMU IRQ that the platform does not see. * IRQ_DB8500_AB8500 and IRQ_PRCMU_BASE go into the platform data because the PRCMU does not see it.

ARM: ux500: move PM-related PRCMU functions to machine

2013-04-08T11:57:53+00:00

We are trying to decompose and decentralize the code in the DB8500 PRCMU out into subdrivers. The code moved in this patch concerns a group of functions used for decoupling and recoupling the IRQs from the GIC. During sleep and idle the Ux500 system will transfer all IRQ handling to the PRCMU using these functions. Basically we are left with the two alternatives of code placement as: - arch/arm/mach-ux500/pm.c - this because the code is closely related to the GIC, and takes ownership of some of the registers from the PRCMU related to this PM functionality. - drivers/mfd/db8500-prcmu-pm.c - because the code is affecting stuff in the PRCMU register range. But then this code needs to remap and handle GIC registers. This patch implementation is taking the first approach. Currently the cpuidle driver is the only piece of code using this set of functions, but it will later also be used by the suspend/resume code which is currently under review. The header file is moved to: The function prototypes need to be placed in a globally visible header since the CPUidle code is planned to move out to drivers/cpuidle.

mfd: prcmu: pass a base and size with the early initcall

2013-04-08T11:57:27+00:00

This patch will make an early remapping of the PRCMU, to be used when setting up the clocks, that will call down into parts of the PRCMU driver before it is probed. Going forward this will be removed like this: - The mailbox subsystem need to be merged. http://marc.info/?l=linux-kernel&m=136314559201983&w=2 - At this point the PRCMU clock code can be moved over to the ux500 clock driver in drivers/clk/ux500/* and maintained there in a decentralized manner. - This early initcall and PRCMU base parameters become part of the ux500_clk_init() call instead.

2013-02-25T04:00:58+00:00

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 ...
