Subject: drm/mediatek: dp: Add multiple calibration data formats support
X-Git-Tag: v6.6.17~3937^2~23^2~1745

drm/mediatek: dp: Add multiple calibration data formats support

The calibration data formats of eDP and DP are different. We add
"const struct mtk_dp_efuse_fmt *efuse_fmt" to the device data to
define them.
