clk: mmp: add linux/clk.h includes

2015-11-25T22:06:16+00:00

The common clk implementation for MMP broke without anyone noticing
when we stopped including linux/clk.h from the clk-provider header.

This did not show up in the defconfig builds because those use the
legacy MMP clk drivers, and it did not show up in my randconfig tests
either because I was testing with my mmp multiplatform series
applied, which at some point gained the fixup.

This fixes the three broken files.

clk: mmp: Convert to clk_hw based provider APIs

2015-08-24T23:48:49+00:00

We're removing struct clk from the clk provider API, so switch
this code to using the clk_hw based provider APIs.

clk: fix some determine_rate implementations

2015-07-28T01:13:32+00:00

Some determine_rate implementations are not returning an error
when they failed to adapt the rate according to the rate request.
Fix them so that they return an error instead of silently
returning 0.

clk: change clk_ops' ->determine_rate() prototype

2015-07-28T01:12:01+00:00

Clock rates are stored in an unsigned long field, but ->determine_rate()
(which returns a rounded rate from a requested one) returns a long
value (errors are reported using negative error codes), which can lead
to long overflow if the clock rate exceed 2Ghz.

Change ->determine_rate() prototype to return 0 or an error code, and pass
a pointer to a clk_rate_request structure containing the expected target
rate and the rate constraints imposed by clk users.

The clk_rate_request structure might be extended in the future to contain
other kind of constraints like the rounding policy, the maximum clock
inaccuracy or other things that are not yet supported by the CCF
(power consumption constraints ?).
