* Strip redundant code from E-Ink driver * Begin polling for E-Ink update completion sooner In some cases, we might be waiting longer than we need to. * E-Ink driver for WeAct 1.54" display Currently identical to the popular GDEY0154D67 model. Kept separate now in case the drivers need to diverge in future. * Put back code which sets the number of gate lines
