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. Base on the branch of linus/master v6.2. Change since v2: 1. Remove the applied patch. 2. Change the commit title and the description. Change since v1: 1. Added fine-tuning panel power sequence modification.
