ebafb63dc7 clk: Tag clk core files with SPDX
These are all GPL-2.0 files per the existing license text. Replace the
boiler plate with the tag.

1667393126 clk: Convert to using %pOF instead of full_name
Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

ee177c5d63 clk: Fix __set_clk_rates error print-string
When failing to set a clock the printout emitted is incorrect.
"u32 rate" is formatted as %d and should be %u whereas "unsigned long
clk_set_rate()" is formatted as %ld and should be %lu as per
Documentation/printk-formats.txt.

e2d7933308 clk: clk-conf: Do not print error messages if EPROBE_DEFER
EPROBE_DEFER is not an error, hence printing an error message like

	clk: couldn't get clock 0 for /soc/display@feb00000

may confuse the user.

Suppress error messages in case of probe deferral to fix this.

c200c39b2d clk: clk-conf: Fix error message when clock isn't found
When failing to lookup the assigned clock for setting its parents, we
were previously printing a misleading error message that lead to think
that it was the parent clock what couldn't be found.

Change error message to make clear that it's the assigned clock what
couldn't be found in this case.

2885c3b2a3 clk: Show correct information when fail to set clock rate
This patch shows the correct information for debugging when fail
to set clock rate because original error message shows the error
value instead of current clock rate.

306c342f9c clk: Replace of_clk_get_by_clkspec() with of_clk_get_from_provider()
of_clk_get_by_clkspec() has the same function signature as
of_clk_get_from_provider()

 struct clk *of_clk_get_by_clkspec(struct of_phandle_args
 *clkspec)
 struct clk *of_clk_get_from_provider(struct of_phandle_args
 *clkspec)

except of_clk_get_by_clkspec() checks to make sure clkspec is not
NULL. Let's remove of_clk_get_by_clkspec() and replace the
callers of it (clkconf.c) with of_clk_get_from_provider().

b11a6face1 clk: Add missing of_clk_set_defaults export
The of_clk_set_defaults() function is used in subsystems which can
be built as module. Add the missing symbol export entry so there
is no build errors like:
"ERROR: "of_clk_set_defaults" [drivers/i2c/i2c-core.ko] undefined!".

86be408bfb clk: Support for clock parents and rates assigned from device tree
This patch adds helper functions to configure clock parents and rates
as specified through 'assigned-clock-parents', 'assigned-clock-rates'
DT properties for a clock provider or clock consumer device.
The helpers are now being called by the bus code for the platform, I2C
and SPI busses, before the driver probing and also in the clock core
after registration of a clock provider.
