This adds initial support for the NWL MIPI DSI Host controller found on i.MX8 SoCs. It adds support for the i.MX8MQ but the same IP can be found on e.g. the i.MX8QXP. It has been tested on the Librem 5 devkit using mxsfb. Signed-off-by:

Calling the VRAM helper's prepare_fb() helper now sets the plane's fence object. This will be useful for PRIME support. VRAM helpers don't support buffer sharing ATM, so for now there are no drivers requiring this change. v2: * removed a TODO comment about buffer synchronization Signed-off-by:

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. Changes since v1: * Change type of intel_connector->port in a separate patch - Sean Paul Cc: "Lee, Shawn C" <shawn.c.lee@intel.com> Reviewed-by:

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:
