The local timer clock is based on ARM subsystem clock. This patch obtains a more exact value of that clock by reading PRCMU registers. Using this increases the accuracy of the local timer events.

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.

This platform has been obsoleted and was only available inside of ST-Ericsson, no users of this code are left in the world. This deletes the core U5500 support entirely in the same manner as the obsoleted U8500 silicon was previously deleted.

In the case we go to the retention mode, we decoupled the gic in order to have the A9 core to reach a stable WFI state. But we want the prcmu to wake up the A9 when the gic has a pending irq which is done by copying the gic settings to the to the prcmu.

This patch introduces a routine to check if there are some irqs pending on the gic. Usually this check is not relevant because it appears racy (an irq can arrive right after this check), but in the ux500 it makes sense because the prcmu decouples the gic from the A9 cores.

This patch allows to decouple and recouple the gic from the PRCMU. This is needed to put the A9 core in retention mode with the cpuidle driver.

This patch adds an initial PRCMU register access API, which for now should only be used for a very limited set of registers. The idea about this API is that we split the PRCMU driver in one part that deals with interaction with the PRCMU firmware and one part that simply provide write accessors in the PRCMU register range. The latter are just a collection of registers exposed in the PRCMU register range for various purposes and not related to the PRCMU firmware. Currently we support some limited GPIO, SPI and UART settings through this API.

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.

This prefixes a number of accessor functions with db8500_* since they are DB8500-specific and we need to move to this naming scheme. We also replace numerous instances of machine_is() with cpu_is() which covers the right type of ASICs rather than entire machines i.e. boards.

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.
