Subject: [PATCHv2 12/22] drm/bridge: tc358767: remove unnecessary msleep
Date: Tue, 26 Mar 2019 12:31:36 +0200 [thread overview]
Message-ID: <20190326103146.24795-13-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <20190326103146.24795-1-tomi.valkeinen@ti.com>
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.
