If anyone has any objections, please let me know. ------------------ From: Sebastian Reichel [ Upstream commit f1080f82570b797598c1ba7e9c800ae9e94aafc6 ] The prepare timing specified by the G190EAN01 datasheet should be between 30 and 50 ms. Considering it might take some time for the LVDS encoder to enable the signal, we should only wait the min. required time in the panel driver and not the max. allowed time.
