[PATCH 1/3] drm: panel: simple: Allow timing constraints, not fixed delays

2020-10-27 Thread Douglas Anderson
The simple panel code currently allows panels to define fixed delays at certain stages of initialization. These work OK, but they don't really map all that clearly to the requirements presented in many panel datasheets. Instead of defining a fixed delay, those datasheets provide a timing diagram
