imx-drm: core: handling of DI clock flags to ipu_crtc_mode_set() We do not need to track the state of the IPU DI's clock flags by having each display bridge calling back into imx-drm-core, and then back out into ipuv3-crtc.c. ipuv3-crtc can instead just scan the list of encoders to retrieve their type, and build up a picture of which types of encoders are attached. We can then use this information to configure the IPU DI clocking mode without any uncertainty - if we have multiple bridges connected to the same DI, if one of them requires a synchronous DI clock, that's what we must use.

imx-drm: use supplied drm_device where possible The component helper provides us the drm_device which is being registered. Rather than having to reference a global in imx-drm-core, use this to get the imxdrm device, and also use it to register the CRTC against. This means we never have CRTCs/encoders/connectors without the drivers private data being accessible. Remove the module owner field as well; this provides no protection against the device being unbound.

staging: imx-drm-core: Use OF graph to find components and connections between encoder and crtcs This patch adds support to find the involved components connected to the IPU display interface ports using the OF graph bindings documented in Documentation/devicetree/bindings/media/video-interfaces.txt. It makes use of the of_graph (formerly v4l2_of) parsing helpers and thus depends on the patch that moves those out to drivers/of. Each display interface needs to have an associated port node in the device tree. We can associate this node with the crtc platform device and use it to find the crtc corresponding to a given port node instead of using a combination of parent device node and id number, as before. Explicitly converting the void* cookie to the port device tree node allows to get rid of the ipu_id and di_id fields. The multiplexer setting on i.MX6 now can be obtained from the port id (reg property) in the device tree. The imx-drm node now needs a ports property that contains phandles to each of the IPU display interface port nodes. From there, all attached encoders are scanned and enabled encoders are added to a waiting list. The bind order makes sure that once all components are probed, crtcs are bound before encoders, so that imx_drm_encoder_parse_of can be called from the encoder bind callbacks. For parsing the OF graph, temporary copies of the V4L2 OF graph helpers are used, that can be removed again once those are available at a generic place.
