clk: qcom: Make common clk_hw registrations

2019-02-22T08:06:57Z

Several clock controller drivers define a list of clk_hw devices, and then register those devices in probe() before using common code to process the rest of initialization. Extend the common code to accept a list of clk_hw devices to process, thus eliminating many duplicate implementations.

clk: qcom: Support 'protected-clocks' property

2018-11-21T08:59:28Z

Certain firmware configurations "protect" clks and cause the entire system to reboot when a non-secure OS such as Linux tries to read or write protected clk registers. But other firmware configurations allow reading or writing the same registers, and they may actually require that the OS use the otherwise locked down clks. Support the 'protected-clocks' property by never registering these protected clks with the common clk framework. This way, when firmware is protecting these clks we won't have the chance to ever read or write these registers and take down the entire system.

clk: qcom: Register the gdscs before the clocks

2018-06-01T18:14:52Z

We have atleast some instances of ALWAYS_ON gdscs, which need to be turned ON *before* some clocks within the gdsc domain marked with a CLK_IS_CRITICAL can be turned ON. To facilitate this sequence, register the GDCSs (and hence handle the ALWAYS_ON gdscs) before we register clocks (and handle the clocks marked as CLK_IS_CRITICAL) Signed-off-by: Rajendra Nayak Reviewed-by: Bjorn Andersson Tested-by: Srinivas Kandagatla Signed-off-by: Stephen Boyd

clk: qcom: common: fix legacy board-clock registration

2017-11-14T23:53:29Z

Make sure to search only the child nodes of "/clocks", rather than the whole device-tree depth-first starting at "/clocks" when determining whether to register a fixed clock in the legacy board-clock registration helper.

clk: qcom: common: Migrate to devm_* APIs for resets and clk providers

2017-11-02T06:37:20Z

Now that we have devm APIs for the reset controller and of clk hw provider APIs we can remove the custom code here. Signed-off-by: Stephen Boyd

scripts/spelling.txt: add regsiter -> register spelling mistake

This typo is quite common. Fix it and add it to the spelling file so that checkpatch catches it earlier. Link: http://lkml.kernel.org/r/20170317011131.6881-2-sboyd@codeaurora.org Signed-off-by: Stephen Boyd Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

clk: qcom: Do not drop device node twice

2017-02-16T01:17:55Z

of_find_node_by_name() drops the reference to a passed device node. It is not necessary to drop it again, and doing so may result in the device node being released prematurely.

clk: qcom: Add rcg ops to return floor value closest to the requested rate

2016-11-23T19:00:05Z

The default behaviour with clk_rcg2_ops is for the clk_round_rate()/clk_set_rate() to return/set a ceil clock rate closest to the requested rate by looking up the corresponding frequency table. However, we do have some instances (mainly sdcc on various platforms) of clients expecting a clk_set_rate() to set a floor value instead. Add a new clk_rcg2_floor_ops to handle this for such specific rcg instances Signed-off-by: Rajendra Nayak Signed-off-by: Ritesh Harjani Signed-off-by: Stephen Boyd
