PM / clk: Add support for adding a specific clock from device-tree

2016-06-27T22:42:10+00:00

Some drivers using the PM clocks framework need to add specific clocks
from device-tree using a name by calling the functions
of_clk_get_by_name() and then pm_clk_add_clk(). Rather than having
drivers call both functions, add a helper function of_pm_clk_add_clk()
that will call these functions so drivers can call a single function
to add a specific clock from device-tree.

PM / clk: Add support for obtaining clocks from device-tree

2016-03-17T01:32:04+00:00

The PM clocks framework requires clients to pass either a con-id or a
valid clk pointer in order to add a clock to a device. Add a new
function of_pm_clk_add_clks() to allows device clocks to be retrieved
from device-tree and populated for a given device. Note that it is
not necessary to make the compilation of this new function dependent
upon CONFIG_OF because there are stubs functions for the device-tree
APIs used.

In order to handle errors encountered when adding clocks from
device-tree, add a function pm_clk_remove_clk() to remove any clocks
(using a pointer to the clk structure) that have been added
successfully before the error occurred.

PM / clock_ops: Provide default runtime ops to users

2015-05-12T21:55:37+00:00

Most users of PM clocks do the extact same things in the runtime
suspend/resume callbacks. Provide them USE_PM_CLK_RUNTIME_OPS so
as to avoid/remove boilerplate code.

PM / clock_ops: Add pm_clk_add_clk()

2014-11-07T00:46:51+00:00

The existing pm_clk_add() allows to pass a clock by con_id. However,
when referring to a specific clock from DT, no con_id is available.

Add pm_clk_add_clk(), which allows to specify the struct clk * directly.
The will will increment refcount on clock pointer, so the caller has
to use clk_put() on clock pointer when done.

PM: Move clock-related definitions and headers to separate file

2011-08-25T13:34:19+00:00

Since the PM clock management code in drivers/base/power/clock_ops.c
is used for both runtime PM and system suspend/hibernation, the
definitions of data structures and headers related to it should not
be located in include/linux/pm_rumtime.h.  Move them to a separate
header file.
