clk: add clk_valid()

2018-08-03T23:53:10+00:00

Add clk_valid() to check for optional clocks are valid.
Call clk_valid() in test/dm/clk.c and add relevant test routine to
sandbox clk tests.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

clk: Add get/enable/disable/release for a bulk of clocks

2018-04-10T15:52:16+00:00

This patch adds a "bulk" API to the clock API in order to get/enable/disable
/release a group of clocks associated with a device.

This bulk API will avoid adding a copy of the same code to manage
a group of clocks in drivers.

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.
