[PATCH v5 07/10] drm/mediatek: dp: Move PHY registration to new function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In preparation for adding support for eDP, move the PHY registration
code to a new mtk_dp_register_phy() function for better readability.

This commit brings no functional changes.
