We want camcc_gdsc_clk for retention, however CLK_CRITICAL is not compatible with pm_runtime suspend and power collapse. - Konrad, Bod - Uses gcc.yaml instead of camcc-common.yaml - Krzysztof - Drops fix for 8550, TBH I didn't know use for socname-ip.yaml with compat strings for different drivers was OK, so long as the content of the yaml was compliant for both. - Krzysztof - Drops clock-names, adds RB as indicated - Konrad - Reworks "really_probe" to account for patch from Lou Jie which is RB from Stephen Boyd but not in any -next tree I can point to right now. - Konrad, Bod - :g/CAM_CC/s//CAMCC/g - Bod Link: https://git.codelinaro.org/bryan.odonoghue/kernel/-/commits/clk-for-6.7-camcc-sc8280xp-v3 V2: I've expanded the scope of this series to include some fixups for the camcc.yaml in general. - Adds qcom,camcc-common.yaml There are a number of repeated patterns in the various camcc yaml files which we can contain in a common camcc .yaml instead. I used gcc.yaml as a base per Krzysztof's suggestion. - Adding the common values file I noticed that sm8450 and sm8550 were both listed as compatible strings in qcom,sm8450-camcc.yaml. This appears to be in error though since sm8450 and sm8550 are not compat strings of the same driver but different drivers entirely. - Switches to indexing, instead of fw_name for clocks - Konrad - Adds the GCC AHB to the clock index - Bod/Konrad - Changes reference "cam_cc" to "camcc" throughout camcc-sc8280xp.c Link: https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/linux-next-26-10-23-sc8280xp-camcc-v2 V1: This is a bog-standard series to add in the CAMCC for 8280xp. As a precursor to adding in sc8280xp I thought a bit of tidy up on the existing yaml for the camcc controllers in general would be worthwhile. As a result there's a precursor patch which aggregates the various camcc yaml files into one location. The sc8280xp looks like sdm845 with more blocks. Similar to sc8280xp we park GDSC to CXO. Thanks to Dmitry for the suggestion the GDSC parking.
