That way we can ditch our gem_prime_res_obj implementation. Since ttm absolutely needs the right reservation object all the boilerplate is already there and we just have to wire it up correctly. Note that gem/prime doesn't care when we do this, as long as we do it before the bo is registered and someone can call the handle2fd ioctl on it. Aside: ttm_buffer_object.ttm_resv could probably be ditched in favour of always passing a non-NULL resv to ttm_bo_init(). At least for gem drivers that would avoid having two of these, on in ttm_buffer_object and the other in drm_gem_object, one just there for confusion.

If the panel is wrapped in a panel_bridge it gets prepar()ed before the upstream DSI bridge which can cause hangs (e.g. with imx-nwl since clocks are not enabled yet). To avoid this move the panel's first DSI access to enable() so the upstream bridge can prepare the DSI host controller in it's pre_enable(). This is also in line with other panel drivers.

In the patch ("video: of: display_timing: Don't yell if no timing node is present") we'll stop spouting an error directly in of_get_display_timing() if no node is present. Presumably amba-clcd should take charge of spouting its own error now. NOTE: we'll print two errors if the node was present but there were problems parsing the timing node (one in of_parse_display_timing() and this new one). Since this is a fatal error for the driver's probe (and presumably someone will be debugging), this should be OK.

Set the connector's kernel device as the parent for the aux kernel device. This allows udev rules to access connector attributes when creating symlinks to aux devices. For example, the following udev rule: SUBSYSTEM=="drm_dp_aux_dev", SUBSYSTEMS=="drm", ATTRS{edid}=="*", SYMLINK+="drm_dp_aux/by-name/$id" Will create the following symlinks using the connector's name: $ ls /dev/drm_dp_aux/by-name/ card0-DP-1 card0-DP-2 card0-DP-3 Cc: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Cc: Jerry (Fangzhi) Zuo <Jerry.Zuo@amd.com> Cc: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Leo Li <sunpeng.li@amd.com> Signed-off-by: Harry Wentland <harry.wentland@amd.com> Reviewed-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190723232808.28128-6-sunpeng.li@amd.com

All available downstream ports - physical and logical - are exposed for each MST device. They are listed in /dev/, following the same naming scheme as SST devices by appending an incremental ID. Although all downstream ports are exposed, only some will work as expected. Consider the following topology: +---------+ | ASIC | +---------+ Conn-0| | +----v----+ +----| MST HUB |----+ | +---------+ | | | |Port-1 Port-2| +-----v-----+ +-----v-----+ | MST | | SST | | Display | | Display | +-----------+ +-----------+ |Port-1 x MST Path | MST Device ----------+---------------------------------- sst:0 | MST Hub mst:0-1 | MST Display mst:0-1-1 | MST Display's disconnected DP out mst:0-1-8 | MST Display's internal sink mst:0-2 | SST Display On certain MST displays, the upstream physical port will ACK DPCD reads. However, reads on the local logical port to the internal sink will *NAK*. i.e. reading mst:0-1 ACKs, but mst:0-1-8 NAKs. There may also be duplicates. Some displays will return the same GUID when reading DPCD from both mst:0-1 and mst:0-1-8. There are some device-dependent behavior as well. The MST hub used during testing will actually *ACK* read requests on a disconnected physical port, whereas the MST displays will NAK. In light of these discrepancies, it's simpler to expose all downstream ports - both physical and logical - and let the user decide what to use. v3 changes: * Change WARN_ON_ONCE -> DRM_ERROR on dpcd read errors * Docstring and cosmetic fixes v2 changes: Moved remote aux device (un)registration to new mst connector late register and early unregister helpers. Drivers should call these from their own mst connector function hooks. This is to solve an issue during driver unload, where mst connector devices are unregistered before the remote aux devices are. In a setup where aux devices are created as children of connector devices, the aux device would be removed too early, and uncleanly. Doing so in early_unregister solves this issue, as that is called before connector unregistration.

VIA_WAIT_ON() is a direct copy of DRM_WAIT_ON() from drm_os_linux.h. The copy is made so we can avoid the dependency on the legacy header. A more involved approach had been to introduce wait_event_* but for this legacy driver the simpler and more safe approach with a copy of the macro was selected. Added the relevant header files for the functions used in VIA_WAIT_ON. v3: - Updated users of DRM_WAIT_ON => VIA_WAIT_ON (Emil) - Updated $subject (Emil) Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Cc: Kevin Brace <kevinbrace@gmx.com> Cc: Thomas Hellstrom <thellstrom@vmware.com> Cc: "Gustavo A.
