2021-03-04drm/mcde/panel: Inverse misunderstood flagLinus Walleij
A recent patch renaming MIPI_DSI_MODE_EOT_PACKET to MIPI_DSI_MODE_NO_EOT_PACKET brought to light the misunderstanding in the current MCDE driver and all its associated panel drivers that MIPI_DSI_MODE_EOT_PACKET would mean "use EOT packet" when in fact it means the reverse. Fix it up by implementing the flag right in the MCDE DSI driver and remove the flag from panels that actually want the EOT packet.

2020-09-06drm/panel: s6e63m0: Fix up DRM_DEV* regressionLinus Walleij
Ooops the panel drivers stopped to use DRM_DEV* messages and we predictably create errors by merging code that still use it.

2020-09-05drm/panel: s6e63m0: Add reading functionalityLinus Walleij
This adds code to send read commands to read a single byte from the display, in order to perform MTP ID look-up of the mounted panel on the s6e63m0 controller. This is needed for proper biasing on the DSI variants.

2020-09-05drm/panel: s6e63m0: Add DSI transportLinus Walleij
This makes it possible to use the s6e63m0 panel with a DSI host, such as in the Samsung GT-I8190 (Golden) mobile phone.
