In the old txt situation we add/describe only properties that are used by the driver/hardware itself. With yaml it also filters things in a node that are used by other drivers like 'assigned-clocks' and 'assigned-clock-rates' for rk3399 and 'power-domains' for most Rockchip Socs in 'vop' nodes, so add them to 'rockchip-vop.yaml'.

Drive-by fix I noticed the other day - drm_dp_mst_has_audio() only ever made sense back when we still had to validate ports before accessing them in order to (attempt to) avoid NULL dereferences. Since we have proper reference counting that guarantees we always can safely access the MST port, there's no use in keeping this function around as all it does is validate the port pointer before checking the audio status. Note - drm_dp_mst_port->has_audio is technically protected by drm_device->mode_config.connection_mutex, since it's only ever updated from drm_dp_mst_get_edid(). Additionally, we change the declaration for port in struct intel_connector to be properly typed, so we can directly access it.

The only reason for having this cast as void * before was because we originally needed to use drm_dp_mst_get_port_validated() and friends in order to (attempt to) safely access MST ports. However, we've since improved how reference counting works with ports and mstbs such that we can now rely on drm_dp_mst_port structs remaining in memory for as long as the driver needs. This means we don't really need to cast this as void* anymore, and can just access the struct directly. We'll also need this for the next commit, so that we can remove drm_dp_mst_port_has_audio().

It looks like that when we introduced the ability to handle multiple down requests at once, we accidentally started dropping NAK replies - causing sideband messages which got NAK'd to seemingly timeout and cause all sorts of weirdness. So, fix this by making sure we don't return from drm_dp_mst_handle_down_rep() early, but instead treat NAKs like any other message. Signed-off-by:

Pankaj Bharadiya started cleaning up the MST connector callbacks a while ago, as I pointed out that they are the same across every driver and don't serve much purpose. There was one callback that was left over though from amdgpu, that we delayed removing due to not being completely sure as to whether or not it was needed. So, I've read through said callback and can confirm it's not at all needed. Pretty much all of the work that is done in dm_dp_destroy_mst_connector() can be done in dm_dp_mst_connector_destroy(). Additionally, I've removed some bits that didn't actually do anything: * Removed DRM_INFO message we were printing, this shouldn't be info level and there's more appropriate drm debugging flags that should be used instead * Removed amdgpu_dm_update_freesync_caps() - reading into this function, it doesn't actually do anything important and I'm not sure why it was ever being called here * Stop clearing aconnector->dc_sink - this also doesn't do anything * Stop clearing link settings in dc_link - this also doesn't do anything * Also, use shorter variable Signed-off-by:
