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.

On OMAP4+ platforms the functional clock for the McPDM IP is suplied by the twl6040 codec (bit clock on the PDM bus). This common clock driver for twl6040 will register the mcpdm_fclk clock to be used by the McPDM driver to make sure that the needed clocks are available when needed.

This patch supports max77686 mfd's clock driver using common clock frame work. max77686 has 3 clock ouputs which all are generated from crystal oscillator and SOC can enable/disable them via I2C bus. All clocks are fixed-rate clock sources so that it doesn't supply interface for changing clock rate. Driver uses regmap API to communicate with internal register.

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.

The WM831x and WM832x series of PMICs contain a flexible clocking subsystem intended to provide always on and system core clocks. It features: - A 32.768kHz crystal oscillator which can optionally be used to pass through an externally generated clock. - A FLL which can be clocked from either the 32.768kHz oscillator or the CLKIN pin. - A CLKOUT pin which can bring out either the oscillator or the FLL output. - The 32.768kHz clock can also optionally be brought out on the GPIO pins of the device. This driver fully supports the 32.768kHz oscillator and CLKOUT. The FLL is supported only in AUTO mode, the full flexibility of the FLL cannot currently be used. Due to a lack of access to systems where the core SoC has been converted to use the generic clock API this driver has been compile tested only.

All platforms that use the common clk infrastructure should select COMMON_CLK from platform code, and on all other platforms, it must not be enabled, so there is no point making the option visible to users, and when it is visible, we break randconfig builds.

The common clock framework defines a common struct clk useful across most platforms as well as an implementation of the clk api that drivers can use safely for managing clocks. The net result is consolidation of many different struct clk definitions and platform-specific clock framework implementations. This patch introduces the common struct clk, struct clk_ops and an implementation of the well-known clock api in include/clk/clk.h. Platforms may define their own hardware-specific clock structure and their own clock operation callbacks, so long as it wraps an instance of struct clk_hw. See Documentation/clk.txt for more details. This patch is based on the work of Jeremy Kerr, which in turn was based on the work of Ben Herrenschmidt.

Now most of ARM machines has the alsmot same __clk_get/put() macro So place it at the arch/arm/include/asm/clkdev.h and remove the reduntant header files But some machines don't have the same form as above. It can use the machince specific clkdev file by HAVE_MACH_CLKDEV config Now there are only 3 caese. 1) define the clk structure with clkdev macro => Need to move clk structure to proper header file arch/arm/mach-versatile/include/mach/clkdev.h arch/arm/mach-realview/include/mach/clkdev.h arch/arm/mach-vexpress/include/mach/clkdev.h arch/arm/mach-integrator/include/mach/clkdev.h 2) export the __clk_get/put function at clock.c arch/arm/mach-shmobile/include/mach/clkdev.h 3) demuxing the clk source arch/arm/mach-u300/include/mach/clkdev.h Acked-by: NViresh Kumar <viresh.kumar@st.com> Acked-by: NH Hartley Sweeten <hsweeten@visionengravers.com> Acked-by: NJean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: NKyungmin Park <kyungmin.park@samsung.com>
