clk: add flag for clocks that need to be enabled on rate changes

2015-12-23T20:57:31Z

Some clocks need to be enabled to accept rate changes. This patch adds a new flag CLK_SET_RATE_UNGATE that lets clk_change_rate enable the clock before trying to change the rate and disable it again afterwards. This of course doesn't effect clocks that are already running at that point, as their refcount will only temporarily increase.

clk: let of_clk_get_parent_name() fail for invalid clock-indices

2015-12-03T06:34:43Z

Currently, of_clk_get_parent_name() returns a wrong parent clock name when "clock-indices" property exists and the target index is not found in the property. In this case, NULL should be returned. For example, oscillator { compatible = "myclocktype"; #clock-cells = <1>; clock-indices = <1>, <3>; clock-output-names = "clka", "clkb"; }; consumer { compatible = "myclockconsumer"; clocks = <&oscillator 0>, <&oscillator 1>; }; Currently, of_clk_get_parent_name(consumer_np, 0) returns "clka" (and of_clk_get_parent_name(consumer_np, 1) also returns "clka", this is correct). Because the "clock-indices" in the clock parent does not contain <0>, of_clk_get_parent_name(consumer_np, 0) should return NULL. Signed-off-by: Masahiro Yamada Signed-off-by: Stephen Boyd

clk: use IS_ERR_OR_NULL(hw) instead of !hw || IS_ERR(hw)

clk: remove redundant negative index check in of_clk_get_parent_name()

2015-11-20T17:18:24Z

This if-block can be dropped because the of_parse_phandle_with_args() in the following line returns -EINVAL for negative index. Signed-off-by: Masahiro Yamada Signed-off-by: Stephen Boyd

clk: Add clk_hw_is_enabled() for use by clk providers

2015-10-26T19:36:55Z

Add clk_hw_is_enabled() to the provider APIs so clk providers can use a struct clk_hw instead of a struct clk to check if a clk is enabled or not. Signed-off-by: Joachim Eastwood Signed-off-by: Stephen Boyd

clk: add missing of_node_put

2015-10-21T23:16:32Z

for_each_matching_node_and_match performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. A simplified version of the semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // @@ expression e1,e2,e; local idexpression np; @@ for_each_matching_node_and_match(np, e1, e2) { ... when != of_node_put(np) when != e = np ( return np; | + of_node_put(np); ? return ...; ) ... } // Besides the problem identified by the semantic patch, this patch adds an of_node_get in front of saving np in a field of parent, to account for the fact that this value will be put on going on to the next element in the iteration, and then adds of_node_puts in the two loops where the parent pointer can be freed.

clk: Make clk input parameter of __clk_get_name() const

2015-10-16T18:56:19Z

When calling __clk_get_name() on a const clock: warning: passing argument 1 of '__clk_get_name' discards 'const' qualifier from pointer target type include/linux/clk-provider.h:613:13: note: expected 'struct clk *' but argument is of type 'const struct clk *' __clk_get_name() does not modify the passed clock, hence make it const.
