ARM: ux500: move PM-related PRCMU functions to machine 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: <linux/platform_data/arm-ux500-pm.h> 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: db8500-prcmu: get base address from resource We cannot use a global variable stored in <mach/hardware.h> to find the base address of the PRCMU. The real resource is already there from the board, so use this to look up the base address instead. Currently the patch is kept minimal so as not to interfere with other work being done on refactoring this driver, but at a later point the defines using (prcmu_base + 0xnnn) need to be replaced by pure offset defined for (0xnnn) and the base inlined with the readl()/writel() and similar codepaths.

mfd: prcmu: pass a base and size with the early initcall 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.

This deletes the core U5500 support entirely in the same manner as the obsoleted U8500 silicon was previously deleted. The cpu_is_u5500() macros that can read out the CPU ID is left until the next kernel cycle, this makes it possible to merge deletion of dependent drivers without breakage.

ARM: mach-ux500: unlock I&D l2x0 caches before init Apparently U8500 U-Boot versions may leave the l2x0 locked down before executing the kernel. Make sure we unlock it before we initialize the l2x0. This fixes a performance problem reported by Jan Rinze. The l2x0 core has been modified to unlock the l2x0 by default, but it will not touch the locking registers if the l2x0 was already enabled, as on the ux500, so we need this quirk to make sure it is properly turned off.

mach-ux500: move the DB8500 PRCMU driver to MFD 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.

ARM: ux500 specific L2 cache code The generic version of l2x0_inv_all is only called just after disabling the L2 cache and is surrounded by a spinlock. However, we're not really turning off the L2 cache right now, and the PL310 does not support exclusive accesses (used to implement the spinlock). So, the invalidation needs to be done without the spinlock.

ARM: 6145/1: ux500 MTU clockrate correction This adjusts the clockrate for the MTU timer. On the different UX500 variants this rate is different. The platform can also have been set up at hardware initialization, bootloader or early init for different clock speeds. To have the clock framework available early so the timers can use them, the clock initialization for Nomadik and ux500 is moved to IRQ init time. A custom per-clock callback is added to handle special cases like this. This solves a user-visible bug: without this patch the current UX500 platforms will not be synchronized to wall-clock time and the platform will drift in time.
