The timing subnode is directly here to avoid having display parameters spread all over the plate. Supplies are organized the same way as in the fbdev driver in the NXP/Freescale kernel forks. The regulators used for that purpose, like the TPS65185, the SY7636A and MAX17135 have typically a single bit to start a bunch of regulators of higher or negative voltage with a well-defined timing. VCOM can be handled separately, but can also be incorporated into that single bit.
