SDM845 has two USB instances each with QUSB2 and QMP PHYs. One of the QMP PHY is USB-DP (DisplayPort) combo PHY where as other one is single lane UNI-PHY (without DP support). Changes are related to PHY configuration for electrical parameters tuning to improve eye-diagram and some fixes. First gcc-msm8996 driver patch is dependent on following patch which is now applied by Stephen. https://patchwork.kernel.org/patch/10375043/ Changes since v4: - Addressed Doug's review comments to have QUSB2 PHY tuning values in header file. - Updated msm8996-gcc patch to use BRANCH_HALT_SKIP flag added by patch - https://patchwork.kernel.org/patch/10375041/ Changes since v3: - As per Doug's review comments added device tree parameters to handle board level differences in PHY tuning values instead of adding separate device tree bindings. - Replace PHY version specific bindings names with SOC name as no one is going to use generic binding names. - Update halt_check to not check for pipe clock status that allows to simplify pipe_clk handling in QMP driver. Changes since v2: - Use separate phy_ops for USB to not register power_on op. - And other minor changes as per review comments from Stephen. Changes since v1: - Updated qusb2 compatibility name as per comment from Vivek.
