Just some tiny edits: - fix link to struct dma_fence - give slightly more meaningful title - the polling here is about implicit fences, explicit fences (in sync_file or drm_syncobj) also have their own polling v2: I misplaced the .rst include change corresponding to this patch. Reviewed-by:

The atomic helpers try really hard to not lose track of things, duplicating enabled tracking in the driver is at best confusing. Double-enabling or disabling is a bug in atomic helpers. In the fb_dirty function we can just assume that the fb always exists, simple display pipe helpers guarantee that the crtc is only enabled together with the output, so we always have a primary plane around. Now in the update function we need to be a notch more careful, since that can also get called when the crtc is off. And we don't want to upload frames when that's the case, so filter that out too.

Implement the drm_bridge_funcs .detect() and .get_edid() operations, and call drm_bridge_hpd_notify() notify to report HPD. This provides the necessary API to support disabling connector creation, do so by accepting DRM_BRIDGE_ATTACH_NO_CONNECTOR in dw_hdmi_bridge_attach(). Signed-off-by:

To prepare for making connector creation optional in the driver, pass the drm_connector explicitly to the internal functions that require it. The functions that still access the connector from the dw_hdmi structure are dw_hdmi_connector_create() and __dw_hdmi_probe(). The former access is expected, as that's where the internal connector is created. The latter will be addressed separately. Signed-off-by:

Replace the drm_connector pointer passed to the .mode_valid() function with a const drm_display_info pointer, as that's all the function should need.

The meson-dw-hdmi driver needs to access its own context from the .mode_valid() operation. It currently gets it from the dev_private field of the drm_device retrieved from the connector, which is a hack. Use the private data passed to the .mode_valid() operation instead. Signed-off-by:

The .configure_phy() operation takes a dw_hdmi_plat_data pointer as a context argument. This differs from .mode_valid() that takes a custom private context pointer, causing possible confusion.

Platform glue drivers for dw_hdmi may need to access device-specific data from their .mode_valid() implementation. They currently have no clean way to do so, and one driver hacks around it by accessing the dev_private data of the drm_device retrieved from the connector. Add a priv_data void pointer to the dw_hdmi_plat_data structure, and pass it to the .mode_valid() function. Signed-off-by:

When validating a mode, bridges may need to do so in the context of a display, as specified by drm_display_info. An example is the meson dw-hdmi bridge that needs to consider the YUV 4:2:0 output format to perform clock calculations. Bridges that need the display info currently retrieve it from the drm_connector created by the bridge. This gets in the way of moving connector creation out of bridge drivers. To make this possible, pass the drm_display_info to drm_bridge_funcs .mode_valid(). Changes to the bridge drivers have been performed with the following coccinelle semantic patch and have been compile-tested. @ rule1 @ identifier funcs; identifier fn; @@ struct drm_bridge_funcs funcs = { ..., .mode_valid = fn }; @ depends on rule1 @ identifier rule1.fn; identifier bridge; identifier mode; @@ enum drm_mode_status fn( struct drm_bridge *bridge, + const struct drm_display_info *info, const struct drm_display_mode *mode ) { ... } Signed-off-by:Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Guido Günther <agx@sigxcpu.org> # for the nwl-dsi part: Signed-off-by:

The drm_bridge_get_edid() function is documented to return an error pointer on error. The underlying .get_edid() operation, however, returns NULL on error, and so do the drm_get_edid() and drm_do_get_edid() functions upon which .get_edid() is usually implemented. Make drm_bridge_get_edid() return NULL on error to be consistent. Signed-off-by:

Now that the driver supports all the connector-related bridge operations, make the connector creation optional. This enables usage of the adv7511 with the DRM bridge connector helper. Signed-off-by:
-
Laurent Pinchart authored
Implement the bridge connector-related .get_edid(), .detect() and .hpd_notify() operations, and report the related bridge capabilities. Output status detection is implemented using the same backend as for the DRM connector, but requires making mode retrieval at detection time optional as no pointer to the connector is available to the bridge .detect() operation. The reason for the need to retrieve modes at detection time is unclear to me, and this may benefit from further refactoring of hot plug handling code. Hot plug detection is notified through the bridge HPD notification framework when the bridge is used without creating a connector, and falls back to the existing implementation otherwise. CEC handling of disconnection is handled in the new .hpd_notify() operation in the new code path. Signed-off-by:

The tfp410 has a data de-skew feature that allows the user to compensate the skew between IDCK and the pixel data and control signals. In the driver, the setup and hold times are calculated from the de-skew value. This retrieves the deskew value from the DT using the proper datatype and range check as described by the binding (u32 from 0 to 7). This fix results from a change in the ti,tfp410 DT binding.
