Add configuration for the 5" Raspberry Pi 720x1280 DSI panel
based on ili9881. This uses 10px longer horizontal sync pulse
and 10px shorter HBP to avoid very short hsync pulse.
Is there a publicly available datasheet for the aforementioned ilitek
controller used in the panel, also does the same document also mention
the manufacturer specific DSC commands used in rpi_5inch_init[] ?
Maybe internet search engine produces some results from some display
manufacturers ?
Also is there a separate document mentioning timing parameters for porch
values and sync pulse widths that you are using here for Raspberry Pi
720x1280 DSI panel ?
Nope, like most of those panel init sequences, this comes from display
vendor or downstream kernel forks, in this case the rpi linux kernel
fork. The timings are slightly adjusted to avoid this very narrow hsync.
