clk: qcom: regmap-mux: fix parent clock lookup

2021-12-14T09:18:06Z

commit 9a61f813fcc8d56d85fcf9ca6119cf2b5ac91dd5 upstream. The function mux_get_parent() uses qcom_find_src_index() to find the parent clock index, which is incorrect: qcom_find_src_index() uses src enum for the lookup, while mux_get_parent() should use cfg field (which corresponds to the register value). Add qcom_find_cfg_index() function doing this kind of lookup and use it for mux parent lookup.

clk: qcom: Allow constant ratio freq tables for rcg

2020-01-04T18:12:51Z

[ Upstream commit efd164b5520afd6fb2883b68e0d408a7de29c491 ] Some RCGs (the gfx_3d_src_clk in msm8998 for example) are basically just some constant ratio from the input across the entire frequency range. It would be great if we could specify the frequency table as a single entry constant ratio instead of a long list, ie: { .src = P_GPUPLL0_OUT_EVEN, .pre_div = 3 }, { } So, lets support that. We need to fix a corner case in qcom_find_freq() where if the freq table is non-null, but has no frequencies, we end up returning an "entry" before the table array, which is bad. Then, we need ignore the freq from the table, and instead base everything on the requested freq.

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

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
