clk: Add (devm_)clk_get_optional() functions

2019-02-06T18:33:10+00:00

This adds clk_get_optional() and devm_clk_get_optional() functions to get optional clocks. They behave the same as (devm_)clk_get() except where there is no clock producer. In this case, instead of returning -ENOENT, the function returns NULL. This makes error checking simpler and allows clk_prepare_enable, etc to be called on the returned reference without additional checks.

clk: add devm_get_clk_from_child() API

2016-12-09T00:37:33+00:00

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 [sboyd@codeurora.org: Rename subject to clk + add API] Signed-off-by: Stephen Boyd

ARM: 7537/1: clk: Fix release in devm_clk_put()

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 Signed-off-by: Russell King

ARM: 7534/1: clk: Make the managed clk functions generically available

2012-09-15T20:55:27+00:00

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.
