2016-12-08	clk: add devm_get_clk_from_child() API	Kuninori Morimoto	1	-0/+21
	Some driver is using this type of DT bindings for clock (more detail, see ${LINUX}/Documentation/devicetree/bindings/sound/simple-card.txt). sound_soc { ... cpu { clocks = <&xxx>; ... }; codec { clocks = <&xxx>; ... }; }; Current driver in this case uses of_clk_get() for each node, but there is no devm_of_clk_get() today. OTOH, the problem of having devm_of_clk_get() is that it encourages the use of of_clk_get() when clk_get() is more desirable. Thus, this patch adds new devm_get_clk_from_chile() which explicitly reads as get a clock from a child node of this device. By this function, we can also use this type of DT bindings sound_soc { clocks = <&xxx>, <&xxx>; clock-names = "cpu", "codec"; clock-ranges; ... cpu { ... }; codec { ... }; }; Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> [sboyd@codeurora.org: Rename subject to clk + add API] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2012-09-19	ARM: 7537/1: clk: Fix release in devm_clk_put()	Mark Brown	1	-1/+1
	Surprisingly devres_destroy() doesn't call the destructor for the resource it is destroying, use the newly added devres_release() instead to fix this. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-09-15	ARM: 7534/1: clk: Make the managed clk functions generically available	Lars-Peter Clausen	1	-0/+55
	The managed clk functions are currently only available when the generic clk lookup framework is build. But the managed clk functions are merely wrappers around clk_get and clk_put and do not depend on any specifics of the generic lookup functions and there are still quite a few custom implementations of the clk API. So make the managed functions available whenever the clk API is implemented. The patch also removes the custom implementation of devm_clk_get for the coldfire platform.
