clk: implement clk_set_defaults()

2018-01-28T16:12:36+00:00

Linux uses the properties 'assigned-clocks', 'assigned-clock-parents'
and 'assigned-clock-rates' to configure the clock subsystem for use
with various peripheral nodes.

This implements clk_set_defaults() and hooks it up with the general
device probibin in drivers/core/device.c: when a new device is probed,
clk_set_defaults() will be called for it and will process the
properties mentioned above.

Note that this functionality is designed to fail gracefully (i.e. if a
clock-driver does not implement set_parent(), we simply accept this
and ignore the error) as not to break existing board-support.

Cover-letter:
clk: support assigned-clock, assigned-clock-parents, assigned-clock-rates

For various peripherals on Rockchip SoCs (e.g. for the Ethernet GMAC),
the parent-clock needs to be set via the DTS.  This adds the required
plumbing and implements the GMAC case for the RK3399.

clk: add clk_set_parent()

2018-01-28T16:12:35+00:00

Clocks may support multiple parents: this change introduces an
optional operation on the clk-uclass to set a clock's parent.

dtoc: Rename the phandle struct

2017-09-15T11:27:47+00:00

Rather than naming the phandle struct according to the number of cells it
uses (e.g. struct phandle_2_cell) name it according to the number of
arguments it has (e.g. struct phandle_1_arg). This is a more intuitive
naming.

Revert "ns16650: Make sure we have CONFIG_CLK set before using infrastructure"

2016-10-08T13:33:31+00:00

This reverts commit 82f5279b0cd99a9163d34cfe926d0316d9dc0d37.

The build failure of k2*evm boards was fixed in a different way by
the previous commit.  It is nasty to patch generic drivers around
with #ifdef CONFIG_CLK just for the KeyStone's matter.

clk: Use dummy clk_get_by_* functions when CONFIG_CLK is disabled

2016-09-21T13:04:32+00:00

The implementations of clk_get_by_index & clk_get_by_name are only
available when CONFIG_CLK is enabled. Provide the dummies when this is
not the case in order to avoid build failures.
