Using different compatibles for basically the same IP block but for a different configuration is bad way all around. There is a new compute platform from Qualcomm that supports both eDP and DP with the same PHY. So instead of following the old method, we should allow the mode to be configured via set_mode from the controller driver. The controller part will follow after we conclude the PHY part first. Signed-off-by: Abel Vesa --- Changes in v2: - Dropped the dedicated xlate function and added set_mode op instead - Dropped the eDP PHY type and mode addition - Added the DP PHY submodes (eDP and DP) - Removed the device match data storing from the container struct - Link to v1: https://lore.kernel.org/r/20231219-x1e80100-phy-edp-compatible-refactor-v1-0-f9e77752953d@linaro.org Initial attepmpt was here: https://lore.kernel.org/all/20231122-phy-qualcomm-edp-x1e80100-v3-3-576fc4e9559d@linaro.org/ Compared to that version, this one uses the phy-cells method and drops the X1E80100 support. The X1E80100 support will be a separate patchset. --- Abel Vesa (2): phy: Add Embedded DisplayPort and DisplayPort submodes phy: qcom: edp: Add set_mode op for configuring eDP/DP submode drivers/phy/qualcomm/phy-qcom-edp.c | 90 ++++++++++++++++++++++++++++--------- include/linux/phy/phy-dp.h | 3 ++ 2 files changed, 72 insertions(+), 21 deletions(-) --- base-commit: 8a9be2a3cb673dba9d22311beb74be261f0b3f15 change-id: 20231219-x1e80100-phy-edp-compatible-refactor-8733eca7ccda Best regards,
