Rajendra Nayak 843be1e7fb clk: qcom: gdsc: Fix handling of hw control enable/disable ... Once a gdsc is brought in and out of HW control, there is a power down and up cycle which can take upto 1us. Polling on the gdsc status immediately after the hw control enable/disable can mislead software/firmware to belive the gdsc is already either on or off, while its yet to complete the power cycle. To avoid this add a 1us delay post a enable/disable of HW control mode. Also after the HW control mode is disabled, poll on the status to check gdsc status reflects its 'on' before force disabling it in software.
