[PATCHv4 13/24] drm/bridge: tc358767: remove unnecessary msleep

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

 



For some reason the driver has a msleep(100) after writing to
DP_PHY_CTRL. Toshiba's documentation doesn't suggest any delay is
needed, and I have not seen any issues with the sleep removed.

Drop it, as msleep(100) is a rather big one.
