clk: Convert __clk_get_name(hw->clk) to clk_hw_get_name(hw)

2015-08-24T23:49:12+00:00

Use the provider based method to get a clock's name so that we
can get rid of the clk member in struct clk_hw one day. Mostly
converted with the following coccinelle script.

@@
struct clk_hw *E;
@@

-__clk_get_name(E->clk)
+clk_hw_get_name(E)

clk: qcom: Convert to clk_hw based provider APIs

2015-08-24T23:48:52+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: qcom: Give clk-qcom.ko module a GPLv2 license

2015-07-28T18:59:26+00:00

The missing license causes the clk-qcom.ko module to taint the
kernel. Add the appropriate license to avoid taint.

clk: qcom: Set CLK_SET_RATE_PARENT on ce1 clocks

2015-07-28T18:51:40+00:00

The other ce clocks have the flag set, but ce1 doesn't, so
clk_set_rate() doesn't propagate up the tree to the ce1_src_clk.
Set the flag as this is supported.

Merge branch 'clk-determine-rate-struct' into clk-next

2015-07-28T18:51:30+00:00

* clk-determine-rate-struct:
  clk: fix some determine_rate implementations
  clk: change clk_ops' ->determine_rate() prototype

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 ?).
