Subject[PATCH v5 0/7] phy: qcom: Updates for USB PHYs on SDM845
Date
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.

Manu Gautam (7):
clk: msm8996-gcc: Mark halt check as no-op for USB/PCIE pipe_clk
phy: qcom-qmp: Enable pipe_clk before PHY initialization
phy: qcom-qusb2: Fix crash if nvmem cell not specified
dt-bindings: phy-qcom-qmp: Update bindings for sdm845
phy: qcom-qmp: Add QMP V3 USB3 UNI PHY support for sdm845
dt-bindings: phy-qcom-usb2: Add support to override tuning values
phy: qcom-qusb2: Add QUSB2 PHYs support for sdm845
