Daniel Lezcano 34fe6f107e mfd : Check if the other db8500 core is in WFI
This patch allows to check if the other core is in WFI
mode. It is the last check the idle routine has to do before
entering into the retention state.

Mattias Nilsson 6b6fae2b89 mfd: db8500 clock handling update
This updates the clock handling in the DB8500 PRCMU driver with
the latest findings and API changes related to changes in the
backing firmware in the PRCMU.

- Add the necessary interfaces to get the frequencies of the
  clocks and set the rate of some of the clocks.
- Add support for controlling the clocks PLLSOC0, PLLDSI,
  DSI0, DSI1 and DSI escape clocks (DSInESCCLK).
- Correct the PLLSDI enable/disable sequence by using the
  DSIPLL_CLAMPI bit.

After this we will have the interfaces and code to implement the
U8500 clock framework properly.

Mattias Nilsson 73180f85f4 mfd: Move to the new db500 PRCMU API
Now that we have a shared API between the DB8500 and DB5500
PRCMU's, switch to using this neutral API instead. We delete the
parts of db8500-prcmu.h that is now PRCMU-neutral, and calls will
be diverted to respective driver. Common registers are in
dbx500-prcmu-regs.h and common accessors and defines in
<linux/mfd/dbx500-prcmu.h> This way we get a a lot more
abstraction and code reuse.
