2015-05-13	clk: bindings: Fix assigned-clock-rates description	Stephen Boyd	1	-3/+4
	The binding uses assigned-clock-parents when it should use assigned-clock-rates. Furthermore, the part that describes how they relate to the assigned-clocks property is not clear about what is related. Correct and clarify this part of the binding.

2014-07-25	clk: Support for clock parents and rates assigned from device tree	Sylwester Nawrocki	1	-0/+36
	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.

2014-05-12	clk: Improve clock-indices binding documentation	Geert Uytterhoeven	1	-5/+4
	Improve the wording for the clock-indices binding documentation. Also replace "empty nodes" by "empty strings", as reported before by Sergei Shtylyov.

2014-02-23	clk: add clock-indices support	Ben Dooks	1	-0/+17
	Add a property called clock-indices to allow clock-output-names to be used where the index used to lookup a clock is not a 1:1 mapping to the array position in the clock-output-names Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Signed-off-by: Mike Turquette <mturquette@linaro.org>

2012-07-11	clk: add DT clock binding support	Grant Likely	1	-0/+117
	Based on work 1st by Ben Herrenschmidt and Jeremy Kerr, then by Grant Likely, this patch adds support to clk_get to allow drivers to retrieve clock data from the device tree. Platforms scan for clocks in DT with of_clk_init and a match table, and the register a provider through of_clk_add_provider. The provider's clk_src_get function will be called when a device references the provider's OF node for a clock reference. v6 (Rob Herring): - Return error values instead of NULL to match clock framework expectations v5 (Rob Herring): - Move from drivers/of into common clock subsystem - Squashed "dt/clock: add a simple provider get function" and "dt/clock: add function to get parent clock name" - Rebase to 3.4-rc1 - Drop CONFIG_OF_CLOCK and just use CONFIG_OF - Add missing EXPORT_SYMBOL to various functions - s/clock-output-name/clock-output-names/ - Define that fixed-clock binding is a single output v4 (Rob Herring): - Rework for common clk subsystem - Add of_clk_get_parent_name function v3: - Clarified documentation v2: - fixed errant ';' causing compile error - Editorial fixes from Shawn Guo - merged in adding lookup to clkdev - changed property names to match established convention. After working with the binding a bit it really made more sense to follow the lead of 'reg', 'gpios' and 'interrupts' by making the input simply 'clocks' & 'clock-names' instead of 'clock-input-', and to only use clock-output for the producer nodes. (Sorry Shawn, this will mean you need to change some code, but it should be trivial) - Add ability to inherit clocks from parent nodes by using an empty 'clock-ranges' property. Useful for busses. I could use some feedback on the new property name, 'clock-ranges' doesn't feel right to me.
