Subject: [PATCH v3 3/3] phy: qcom: edp: Add support for X1E80100 PHY
The Qualcomm X1E80100 platform has a number of eDP/DP PHY instances. These
are based on QMP v6. So add support for v6 QMP COM registers by supporting
configuration-based register offsets. For legacy platforms, keep the eDP and DP
compatibles different, but for new platforms, use the phy-type DT property
instead. So add platform specific configs, specify the version and override
the PHY type where compatible dictates it.
