Add missing DP PHY status and VCO clock configuration registers to fix configuring the VCO rate on SM8750. Without proper VCO rate setting, it works on after-reset half of rate which is not enough for DP over USB to work as seen on logs: [drm:msm_dp_ctrl_link_train_1_2] *ERROR* max v_level reached [drm:msm_dp_ctrl_link_train_1_2] *ERROR* link training #1 on phy 0 failed. ret=-11 Fixes: c4364048baf4 ("phy: qcom: qmp-combo: Add new PHY sequences for SM8750") Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> --- drivers/phy/qualcomm/phy-qcom-qmp-combo.c | 3 +++ 1 file changed, 3 insertions(+)
