Subject: [PATCH v5 0/7] phy: qcom: Updates for USB PHYs on SDM845
Date: Thu, 3 May 2018 02:30:06 +0530 [thread overview]
Message-ID: <1525294813-15225-1-git-send-email-mgautam@codeaurora.org> (raw)
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.
