2012-09-11ARM: imx6q: replace clk_register_clkdev with clock DT lookupShawn Guo
It really becomes an maintenance issue that every time a device needs to look up (clk_get) a clock we have to patch kernel clock file to call clk_register_clkdev for that clock. Since clock DT support which is meant to resolve clock lookup in device tree is in place, the patch moves imx6q client devices' clock lookup over to device tree, so that any new lookup to be added at later time can just get done in DT instead of kernel.

2012-09-11ARM: imx6q-sabrelite: Rename 'pinctrl_gpio_hog'Fabio Estevam
'pinctrl_gpio_hog' is used to setup the pin functions, and it is not neccesarily used only for GPIO pins, so remove 'gpio' from its name to describe a more generic term. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2012-09-11ARM: imx51: decouple device tree boot from board filesShawn Guo

2012-09-07clk: add of_clk_src_onecell_get() supportShawn Guo

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.

2012-08-24clk: convert ARM RealView to common clkLinus Walleij
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.
