2020-11-05drm/bridge/synopsys: dsi: add support for non-continuous HS clockAntonio Borneo1-2/+7
[ Upstream commit c6d94e37bdbb6dfe7e581e937a915ab58399b8a5 ] Current code enables the HS clock when video mode is started or to send out a HS command, and disables the HS clock to send out a LP command. This is not what DSI spec specify. Enable HS clock either in command and in video mode. Set automatic HS clock management for panels and devices that support non-continuous HS clock.
