ARM/clk: move the ICST library to drivers/clk This moves the ICST clock divider helper library from arch/arm/common to drivers/clk/versatile so it is maintained with the other clock drivers. We keep the structure as a helper library intact and do not fuse it with the clk-icst.c Versatile ICST clock driver: there may be other users out there that need to use this library for their clocking, and then it will be helpful to keep the library contained. (The icst.[c|h] files could just be moved to drivers/clk/lib or a similar location to share the library.)

ARM: vexpress: Remove non-DT code Now, with the CLCD DT support available, there is no more reason to keep the non-DT support for V2P-CA9. Removed, together with "some" supporting code. It was necessary to make PLAT_VERSATILE_SCHED_CLOCK optional and selected by the machines still interested in it.

clk: vexpress: Add separate SP810 driver Factor out the SP810 clocking code into a separate driver, selecting better (faster) parent at clk_prepare() time. This is to avoid problems with clocking infrastructure initialisation order, in particular to avoid dependency of fixed clock being initialized before SP810. It also makes vexpress platform OF-based clock initialisation code unnecessary.

clk: Common clocks implementation for Versatile Express This patch adds a DT and non-DT based implementation of the common clock infrastructure for Versatile Express platform. It registers (statically or using DT) all required fixed clocks, initialises motherboard's SP810 cell (that provides clocks for SP804 timers) and explicitly registers VE "osc" driver, to make the clock generators available early.

clk: convert ARM RealView to common clk This converts the ARM RealView machine over to using the common clock. The approach is similar to the one used for the Integrator, and we're reusing the ICST wrapper code. We have to put the clock intialization in the timer init function for the clocks to be available when initializing the timer, keeping them in early_init() is too early for the common clk. Since we now have to go down and compile drivers/clk/versatile a CONFIG_COMMON_CLK_VERSATILE symbol has been added so the proper code gets compiled into the kernel for either machine. A leftover CLK_VERSATILE in the Integrator Kconfig was fixed up to use the new symbol as well. Tested on ARM RealView PB1176.

ARM: integrator: convert to common clock This converts the Integrator platform to use common clock and the ICST driver. Since from this point not all ARM reference platforms use the clock, we define CONFIG_PLAT_VERSATILE_CLOCK and select it for all platforms except the Integrator. Open issue: I could not use the .init_early() field of the machine descriptor to initialize the clocks, but had to move them to .init_irq(), so presumably .init_early() is so early that common clock is not up, and .init_machine() is too late since it's needed for the clockevent/clocksource initialization. Any suggestions on how to solve this is very welcome.

clk: add versatile ICST307 driver The ICST307 VCO clock has a shared driver in the ARM architecture. This patch provides a wrapper into the common clock framework so we can use the implementation in the ARM architecture without duplicating the code until all ARM platforms using this VCO are moved over. At that point we can merge the driver from the ARM platform into the generic file altogether.
