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: Add a driver for the PLL2 The PLL2 on the A10 and later SoCs is the clock used for all the audio related operations. This clock has a somewhat complex output tree, with three outputs (2X, 4X and 8X) with a fixed divider from the base clock, and an output (1X) with a post divider. However, we can simplify things since the 1X divider can be fixed, and we end up by having a base clock not exposed to any device (or at least directly, since the 4X output doesn't have any divider), and 4 fixed divider clocks that will be exposed. This clock seems to have been introduced, at least in this form, in the revision B of the A10, but we don't have any information on the clock used on the revision A.

clk: sunxi: Add a simple gates driver The gates were handled with a common piece of framework that was registering all gates array, that was not using the CLK_OF_DECLARE logic, and was not using clock-indices but some private masks that were pretty much equivalent.

clk: sunxi: Add H3 clocks support The H3 clock control unit is similar to the those of other sun8i family members like the A23. It adds a new bus gates clock similar to the simple gates, but with a different parent clock for each single gate. Some of the gates use the new AHB2 clock as parent, whose clock source is muxable between AHB1 and PLL6/2. The documentation isn't totally clear about which devices belong to AHB2 now, especially USB EHIC/OHIC, so it is mostly based on Allwinner kernel source code.

clk: sunxi: Add support for A80 basic bus clocks The A80 SoC has 12 PLL clocks, 3 AHB clocks, 2 APB clocks, and a new "GT" bus, which I assume is some kind of data bus connecting the processor cores, memory and various busses. Also there is a bus clock for a ARM CCI400 module. As far as I can tell, the GT bus and CCI400 bus clock must be protected. This patch adds driver support for peripheral related PLLs and bus clocks on the A80. The GT and CCI400 clocks are added as well as these 2 along with the PLLs they are clocked from must not be disabled.

clk: sunxi: Add driver for A80 MMC config clocks/resets On the A80 SoC, the 4 mmc controllers each have a separate register controlling their register access clocks and reset controls. These registers in turn share a ahb clock gate and reset control. This patch adds a platform device driver for these controls. It requires both clocks and reset controls to be available, so using CLK_OF_DECLARE might not be the best way.

clk: sunxi: Move USB clocks to separate file The USB clocks originally shared code with the gates clocks, but had additional reset controllers. Move these to a separate file. This will allow us to add new support for slightly different USB clocks, such as on the A80, without affecting gates clocks, and also facilitate the migration of gates clocks to a generic solution. This also cleans up the USB clocks code slightly, such as adding newlines, getting rid of the unused clkdev call, using a simple u32 instead of BITMAP for the clock masks, using BIT() macro to declare the clock bitmasks, and using of_io_request_and_map() to get the I/O address.

clk: sunxi: Add CLK_OF_DECLARE support for sun8i-a23-apb0-clk driver The APBS clock on sun9i is the same as the APB0 clock on sun8i. With sun9i we are supporting the PRCM clocks by using CLK_OF_DECLARE, instead of through a PRCM mfd device and subdevices for each clock and reset control. As such we need a CLK_OF_DECLARE version of the sun8i-a23-apb0-clk driver. Also, build it for sun9i/A80, and not just for configurations with MFD_SUN6I_PRCM enabled.
