2020-10-26drm: deprecate DRM_FORMAT_MOD_NONESimon Ser1-1/+10
DRM_FORMAT_MOD_NONE is in the list of vendors, which is pretty confusing. We already have DRM_FORMAT_MOD_VENDOR_NONE. Move it down in the list of format modifiers. DRM_FORMAT_MOD_NONE is an alias for DRM_FORMAT_MOD_LINEAR, however the name is confusing: NONE doesn't mean that the modifier is implicit, instead it means that the layout is linear. Deprecate it.

2020-10-22drm/vc4: dsi: Only register our component once a DSI device is attachedMaxime Ripard1-17/+8
If the DSI driver is the last to probe, component_add will try to run all the bind callbacks straight away and return the error code. However, since we depend on a power domain, we're pretty much guaranteed to be in that case on the BCM2711, and are just lucky on the previous SoCs since the v3d also depends on that power domain and is further in the probe order. In that case, the DSI host will not stick around in the system: the DSI bind callback will be executed, will not find any DSI device attached and will return EPROBE_DEFER, and we will then remove the DSI host and ask to be probed later on. But since that host doesn't stick around, DSI devices like the RaspberryPi touchscreen whose probe is not linked to the DSI host (unlike the usual DSI devices that will be probed through the call to mipi_dsi_host_register) cannot attach to the DSI host, and we thus end up in a situation where the DSI host cannot probe because the panel hasn't probed yet, and the panel cannot probe because the DSI host hasn't yet. In order to break this cycle, let's wait until there's a DSI device that attaches to the DSI host to register the component and allow to progress further.

2020-10-22drm: document that user-space should avoid parsing EDIDsSimon Ser1-0/+5
User-space should avoid parsing EDIDs for metadata already exposed via other KMS interfaces and properties. For instance, user-space should not try to extract a list of modes from the EDID: the kernel might mutate the mode list (because of link capabilities or quirks for instance). Other metadata not exposed by KMS can be parsed by user-space. This includes for instance monitor identification (make/model/serial) and supported color-spaces. v2: add short explanation why user-space shouldn't do this (Brian) Signed-off-by: Simon Ser <[email protected]> Suggested-by: Daniel Vetter <[email protected]> Reviewed-by: Daniel Vetter <[email protected]> Reviewed-by: Brian Starkey <[email protected]> Acked-by: Thomas Zimmermann <[email protected]> Cc: Pekka Paalanen <[email protected]> Cc: Ville Syrjälä <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/V_APW3gKRhljvcmT28tGV3JkP7qW9Z7h45I-s2wiJvYhaaveCpYpg3tztZPsZVV2KV1NC7rUx08IUUgCJXzdRrWCsEGB0czq4ZozpdyVFLs=@emersion.fr
