The parse config function now performs action on the device either reading or writing and a reset. If the regulator is managed it needs to be turned on. So turn on the regulator if available if the parsing fails then turn off the regulator.Another BTW: Consider converting the switching of the vsup to runtime_pm. Yet another one: Why do you disable the clocks in the error path of tcan4x5x_can_probe(), but never enable them?quoted
out_clk: if (!IS_ERR(mcan_class->cclk)) { clk_disable_unprepare(mcan_class->cclk); clk_disable_unprepare(mcan_class->hclk); }- please move the clock handling from the m_can.c to the individual driver - please move the clock handling to runtime_pm in the individual driver - remove the obsolete m_can_class_get_clocks() - make runtime_pm mandatory regards, Marc
I have separate the clock calls into pm runtime calls and moved the clock init into the respective children of the framework. Did you want me to submit 1 patch with all the changes or would you like 3 separate patches? First 2 patches will abstract the clocks away into the children and the 3rd patch would be to remove the clocks API from the framework Dan
