Enable DSI EOTP feature for fixing some panel screen constance shift issue. Removing MIPI flag MIPI_DSI_MODE_EOT_PACKET to enable DSI EOTP.
I don't think I quite understand how removing the MIPI_DSI_MODE_EOT_PACKET flag will cause DSI EOTP to be enabled. Could you extrapolate on this in the commit message?
That confused me as well, but it turns out that's how the flag is defined: ``` /* disable EoT packets in HS mode */ #define MIPI_DSI_MODE_EOT_PACKET BIT(9) ``` (https://elixir.bootlin.com/linux/latest/source/include/drm/drm_mipi_dsi.h#L1...)
I'm almost tempted to put together a mass patch to rename all of these flags...
