Subject: [PATCH v3 0/2] phy: qcom: edp: Add DP/eDP switch for phys
Date: Mon, 02 Mar 2026 16:28:28 +0800	[thread overview]
Message-ID: <20260302-edp_phy-v3-0-ca8888d793b0@oss.qualcomm.com> (raw)

Currently the PHY selects the DP/eDP configuration tables in a fixed way,
choosing the table when enable. This driver has known issues:
1. The selected table does not match the actual platform mode.
2. It cannot support both modes at the same time.

As discussed here[1], this series:
1. Cleans up duplicated and incorrect tables based on the HPG.
2. Fixes the LDO programming error in eDP mode.
3. Adds DP/eDP mode switching support.

Note: x1e80100/sa8775p/sc7280 have been tested, while glymur/sc8280xp
have not been tested.
