Subject: [PATCH 1/2] clk: qcom: videocc: Use HW_CTRL_TRIGGER flag for video
 GDSC's

From: Taniya Das <quic_tdas@...cinc.com>

The video driver will be using the newly introduced
dev_pm_genpd_set_hwmode() API to switch the video GDSC to HW and SW
control modes at runtime.
Hence use HW_CTRL_TRIGGER flag instead of HW_CTRL for video GDSC's for
Qualcomm SoC SC7180 and SDM845.
