Subject: [PATCH v4 0/7] phy: qcom: Updates for USB PHYs on SDM845
Date: Thu, 29 Mar 2018 16:34:19 +0530 [thread overview]
Message-ID: <1522321466-21755-1-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.
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.
