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."

mfd: db8500-prcmu: update resource passing

2013-02-12T11:44:27+00:00

When trying to get rid of the cross-includes of 
from different drivers, so we can localize ASIC/CPU detection
to the mach-ux500 folder, we run into the way the PRCMU
handles base addresses and firmware detection.

This patch updates the firmware version detection to pass
the required information as platform data instead of
relying on cpu_is_* macros.

Now the PRCMU base address, the secondary TCDM area, the
TCPM area and the IRQ are passed as resources instead of
being grabbed from  files. Incidentally this also
removes part of the reliance on .

Further it updates the firmware version detection, since the
location of the firmware ID bytes in the designated memory
are is now passed from the platform data instead. There is
no reason not to include the nice split-off of a struct to
hold the firmware information and a separate function to
populate it.

The patch actually rids the need to use the external
db8500_prcmu_early_init call at all, but I'm keepin back
that removal as I don't want the patch to be too big.
