panic() is too heavy for this, indeed the PRCMU is critical for the system but not to the point that we should stop everything, if we can still get a prompt or so. Signed-off-by: NLinus Walleij <linus.walleij@linaro.org> Signed-off-by: NSamuel Ortiz <sameo@linux.intel.com>

This is a tweak for the case where the modem goes to sleep while emitting the AC_WAKE_ACK anyway. Also print the modem errors as critical, since they jeopardize the entire platform when they occur.

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.

Some clocks may be force enabled when we probe the driver, but they need to be turned off by default so we have a known state. We call this the register initialization function if we need more stuff in there in the future.

Instead of carrying around the __PRCMU_BASE in every read or write to the PRCMU registers, move it out to the register definition file and define registers along with their base offset so that the code gets easier to read.

With the addition of a device platform mfd_cell pointer, MFD drivers can go back to passing platform data back to their sub drivers. This allows for an mfd_cell->mfd_data removal and thus keep the sub drivers MFD agnostic. This is mostly needed for non MFD aware sub drivers.

The DB8500 has ePOD:s (electronic power domains) which are possible to switch on/off to deactivate silicon blocks on the DB8500 SoC by cutting their power without retention. We model these as simple regulators with one bit on/off settings.

This updates the DB8500 PRCMU driver to the latest version available internally. Nominally we would update the dependent CPUfreq driver at the same time but since that is being moved around in this patch set we postpone that by simply deactivating it for the time being. This is a snapshot of the current PRCMU firmware API as it looks right now. The PRCMU firmware is still subject to change. This also updates the CPUfreq driver to a newer version that will utilize the new API.

We have decided that this function arbiter fits better in the MFD subsystem. Since we need to concatenate the split header files we move it basically like this: mv mach-ux500/prcmu-db8500.c drivers/mfd/db8500-prcmu.c mv mach-ux500/include/mach/prcmu-defs.h include/linux/mfd/db8500-prcmu.h mv mach-ux500/include/mach/prcmu-regs.h drivers/mfd/db8500-prcmu-regs.h mach-ux500/include/mach/prcmu.h >> include/linux/mfd/db8500-prcmu.h rm arch/arm/mach-ux500/include/mach/prcmu.h Then we update different #include statements and Makefile orders etc to make the PRCMU driver compile, link and boot in the new place without really changing any code.
