clk: sunxi: declare OF clock provider

2013-09-29T19:07:16+00:00

Common clock framework allows to register clock providers to get called
on of_clk_init() by using CLK_OF_DECLARE. This converts sunxi clock
providers to make use of it and get rid of the mach specific clk init
call. As sunxi has a bunch of independent clk provider nodes, we hook
current clock init to board compatible to make it called once.

clk: sunxi: Fix incorrect placement of __initconst

2013-08-28T01:35:43+00:00

__initconst should be placed between the variable name and equal
sign for the variable to be placed in the intended section.

clk: sunxi: Add Allwinner A20 gates

2013-08-26T08:58:21+00:00

The Allwinner A20 is almost identical to the earlier A10 SoC from
Allwinner on many aspects, including the clocks tree. However, since the
A20 has some additionnal IPs compared to the A10, the clock tree isn't
exactly the same, especially when it comes to the gated clocks
available. We thus need to register different clock gates for the A20.

clk: sunxi: Add A31 clocks support

2013-08-26T08:58:11+00:00

The A31 has a mostly different clock set compared to the other older
SoCs currently supported in the Allwinner clock driver.

Add support for the basic useful clocks. The other ones will come in
eventually.

clk: sunxi: Allow to specify the divider width from the dividers data

2013-08-26T08:48:45+00:00

The divider width used to be hardcoded. Some A31 dividers are no longer
with the hardcoded width, so we need to make it specific to each divider
and set it in the dividers data.

clk: sunxi: Rename the structure to prepare the addition of sun6i

2013-08-26T08:48:44+00:00

Rename all the generic-named structure to sun4i to avoid confusion when
we will introduce the sun6i (A31) clocks.

clk: sunxi: fix initialization of basic clocks

2013-08-26T08:48:39+00:00

With the recent move towards CLK_OF_DECLARE(...), the driver stopped
initializing osc32k, which is compatible "fixed-clock". This is because
we never called of_clk_init(NULL). Fix this by moving the only other
simple clock (osc24M) to use CLK_OF_DECLARE(...) and call of_clk_init(NULL)
to initialize both of them.

clk: sunxi: Add A10s gates

2013-08-26T08:46:32+00:00

The Allwinner A10s has a slightly different gates set than the A10 and
A13, so add these gates to the clk driver.

clk: add CLK_SET_RATE_NO_REPARENT flag

2013-08-19T19:27:17+00:00

Add a CLK_SET_RATE_NO_REPARENT clock flag, which will prevent muxes
being reparented during clk_set_rate.

To avoid breaking existing platforms, all callers of clk_register_mux()
are adjusted to pass the new flag. Platform maintainers are encouraged
to remove the flag if they wish to allow mux reparenting on set_rate.
