Reduce lcm_reset to DSI LP11 send cmd time
|
expand
|
From: Xinlei Lee <xinlei.lee@mediatek.com> The panel spec stipulates that after lcm_reset is pulled high, cmd should be sent to initialize the panel. Within the allowable range of the DSI spec, this time needs to be reduced to avoid panel exceptions.
