clk: mxs: make clk_ops const

2017-11-02T06:25:43+00:00

Make these const as they are only stored in the const field of a
clk_init_data structure.

clk: move the common clock's to_clk_*(_hw) macros to clk-provider.h

2016-01-29T20:59:50+00:00

to_clk_*(_hw) macros have been repeatedly defined in many places.
This patch moves all the to_clk_*(_hw) definitions in the common
clock framework to public header clk-provider.h, and drop the local
definitions.

clk:mxs: Fix bug on frequency divider

2015-10-01T22:24:34+00:00

On drivers/clk/mxs/clk-frac.c, the function clk_frac_round_rate returned a bad
result. The division before multiplication computes a wrong value ; the
calculation is inverted to fix the problem. The second issue is that the exact
rate have decimals and they are truncate. The consequence is that the function
clk_frac_set_rate (which use the result of clk_frac_round_rate) computes a
wrong value for the register (the rate generated can be closer to the desired
rate). The correction is : if there is decimal to the result, it is rounded to
the next larger integer.
On drivers/clk/mxs/clk-frac.c, the function clk_frac_recalc_rate returned
a bad result. The multiplication is made before the division to compute a
correct value.

clk: mxs: Include clk.h in C files that use it

2015-07-20T18:11:07+00:00

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. The clk.h include is being included in all
mxs files because it's part of mxs/clk.h even though nothing
actually requires it in that file. Move the clk.h include to the
C files that are actually using it and remove the clk.h include
from the header file. The clkdev.h include isn't used either, so
drop it too.

clk: make several parent names const

2015-06-04T21:27:06+00:00

Since commit 2893c379461a ("clk: make strings in parent name arrays
const") the name of parent clocks can be const. So add more const in
several clock drivers.

clk: don't use __initconst for non-const arrays

2015-04-13T00:18:27+00:00

The statement

	static const char *name[];

defines a modifiable array of pointers to constant chars. That is

	*name[0] = 'f';

is forbidden, but

	name[0] = "f";

is not. So marking an array that is defined as above with __initconst is
wrong. Either an additional const must be added such that the whole
definition reads:

	static const char *const name[] __initconst;

or where this is not possible __initdata must be used.

ARM: mxs: remove custom .init_time hook

2013-09-29T19:09:34+00:00

This patch converts clk-imx2[38] clocksource_of_init compatible init
associated with fsl,imx2[38]-clkctrl. With arch/arm calling
of_clk_init(NULL) from time_init(), we can now also remove custom
.init_time hooks.

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.
