Subject: [PATCH v5 0/7] phy: qcom: Updates for USB PHYs on SDM845
Date: Thu,  3 May 2018 02:36:07 +0530	[thread overview]
Message-ID: <1525295174-15995-1-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.
