clk: qcom: Migrate to clk_hw based registration and OF APIs

2016-08-25T00:37:06+00:00

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers in this driver, allowing us to
move closer to a clear split of consumer and provider clk APIs.

clk: qcom: Remove CLK_IS_ROOT

2016-03-04T20:53:53+00:00

This flag is a no-op now. Remove usage of the flag.

clk: qcom: gdsc: Add support for hierarchical power domains

2016-02-12T00:24:00+00:00

Some qcom SoCs' can have hierarchical power domains. Let the gdsc structs
specify the parents (if any) and the driver add genpd subdomains for them.

clk: qcom: common: check for failure

2016-02-09T01:06:43+00:00

We were not checking the return from devm_add_action() which can fail.
Start using the helper and devm_add_action_or_reset() and return
directly as we know that the cleanup has been done by this helper.

clk: qcom: common: Add API to register board clocks backwards compatibly

2015-11-16T19:07:06+00:00

We want to put the XO board clocks into the dt files, but we also
need to be backwards compatible with an older dtb. Add an API to
the common code to do this. This also makes a place for us to
handle the case when the RPM clock driver is enabled and we don't
want to register the fixed factor clock.

clk: qcom: Drop calls to qcom_cc_remove()

2015-10-09T06:53:01+00:00

Now that qcom_cc_remove() is a nop, drop calls to
qcom_cc_remove() and any empty driver remove functions.

qcom: clk: Make qcom_cc_probe() fully devm safe

2015-10-09T06:53:00+00:00

Some APIs in qcom_cc_probe() don't have a devm counterpart, so we
have to use the calling device's platform data to pass pointers
to the remove path. Let's use devm_add_action() instead, so that
the remove path doesn't need to do anything, allowing us to
remove qcom_cc_remove() entirely.

clk: qcom: gdsc: Add support for ON only state

2015-09-16T22:22:40+00:00

Certain devices can have GDSCs' which support ON as the only state.
They can't be power collapsed to either hit RET or OFF.
The clients drivers for these GDSCs' however would expect the state
of the core to be reset following a GDSC disable and re-enable.
To do this assert/deassert reset lines every time the client
driver would request the GDSC to be powered on/off instead.

clk: qcom: gdsc: Prepare common clk probe to register gdscs

2015-09-16T22:22:37+00:00

The common clk probe registers a clk provider and a reset controller.
Update it to register a genpd provider using the gdsc data provided
by each platform.

clk: Replace __clk_get_num_parents with clk_hw_get_num_parents()

2015-08-24T23:48:43+00:00

Mostly converted with the following semantic patch:

@@
struct clk_hw *E;
@@

-__clk_get_num_parents(E->clk)
+clk_hw_get_num_parents(E)
