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.

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.

mfd: prcmu: delete pin control helpers

2013-01-29T17:47:18+00:00

These static inlines are duplicating the task now done by the
Nomadik pinctrl drivers, so delete them from the prcmu static
inlines, also delete the register definitions as these should
only be known by the pinctrl driver.

mfd: Update db8500-prmcu hostport_access enable

2012-07-08T22:16:10+00:00

Force the Modem wakeup by asserting the CaWakeReq signal before the
hostaccess_req/ack ping-pong sequence. The Awake_req signal is de-asserted
asserted at the same time than the hostaccess_req. Return error on failure
case so that the client using this can take appropiate steps.
