clk: arm: sunxi: Add a new clock driver for sunxi SOCs This commit implements the base CPU clocks for sunxi devices. It has been tested using a slightly modified cpufreq driver from the linux-sunxi 3.0 tree. Additionally, document the new bindings introduced by this patch.

clk: sunxi: Move the GMAC clock to a file of its own Since we have a folder of our own, we can actually make use of it by splitting the huge clock file into several sub drivers. The gmac clock is pretty easy to deal with, since it's pretty much isolated and doesn't have any dependency on the other clocks.

clk: sunxi: add PRCM (Power/Reset/Clock Management) clks support The PRCM (Power/Reset/Clock Management) unit provides several clock devices: - AR100 clk: used to clock the Power Management co-processor - AHB0 clk: used to clock the AHB0 bus - APB0 clk and gates: used to clk peripherals connected to the APB0 bus Add support for these clks in a separate driver so that they can be probed as platform devices instead of registered during early init. This is needed to be able to probe PRCM MFD subdevices.

clk: sunxi: Add A23 APB0 divider clock support The A23 has an almost identical PRCM clock tree. The difference in the APB0 clock is the smallest divisor is 1, instead of 2. This patch adds a separate sun8i-a23-apb0-clk driver to support it.
