Subject: [PATCH v5 0/4] drm/panel: add support for LG SW43408 panel
The LG SW43408 panel is used on Google Pixel3 devices. For a long time
we could not submit the driver, as the panel was not coming up from the
reset. The panel seems to be picky about some of the delays during init
and it also uses non-standard payload for MIPI_DSI_COMPRESSION_MODE.
