Many of the kselftests in DRM can be converted to kunit tests instead, since that framework is more suitable for unit testing. Suggested-by:

'cat /sys/kernel/debug/dma_buf/bufinfo' will print the Dma-buf Objects' information when the CONFIG_DEBUG_FS=y. However, the printed table header information does not contain the name field. So we need to add the name field to the table header and use the '<none>' to replace the empty buf_obj->name. Signed-off-by:

The Northwest Logic MIPI DSI host controller embedded in i.MX8qxp works with a Mixel MIPI DPHY + LVDS PHY combo to support either a MIPI DSI display or a LVDS display. So, this patch calls phy_set_mode() from nwl_dsi_mode_set() to set PHY mode to MIPI DPHY explicitly.

Convert drm_find_cea_extension() to a predicate function to check if the EDID has a CTA extension or a DisplayID CTA data block. This is mainly to avoid adding new users that only find the first CTA extension. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Jani Nikula authored
The DisplayID CTA data block version does not necessarily match the CTA revision. Simplify by postponing drm_edid_to_eld() slightly, and reusing the CTA revision extracted by drm_parse_cea_ext(). By not bailing out early in drm_edid_to_eld() we may end up filling meaningless data to the ELD. However, the main decision for audio is not the ELD, but rather drm_detect_monitor_audio() called by drivers. (Arguably a future cleanup could do that in drm_add_edid_modes() and cache the result in the connector.) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:
