drm: make mode_valid callback optional Many drm connectors do not need mode validation. The patch makes this callback optional and removes dumb implementations. v2: Rebase: - imx move to a shared (but still dummy) ->mode_valid implementation. - probe helpers have been extracted to drm_probe_helper.c Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> (v1) Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

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.

imx-drm: Move IPU_PIX_FMT_GBR24 definition into imx-ipu-v3.h The IPU display controller supports a non-standard green-red-blue ordered format that is used on the connection between IPU display interface 1 and the TV encoder on i.MX53. In preparation for the move of IPU core code out of staging, place the IPU_PIX_FMT_GBR24 definition in imx-ipu-v3.h, so that both the IPU display interface driver and the TVE encoder driver can access it.

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.

imx-drm: remove separate imx-fbdev Now that we know when the components of the imx-drm subsystem will be initialised, we can move the fbdev helper initialisation and teardown into imx-drm-core. This gives us the required ordering that DRM wants in both driver load and unload methods. We can also stop exporting the imx_drm_device_get() and imx_drm_device_put() methods; nothing but the fbdev helper was making use of these.

imx-drm: simplify setup of panel format The encoder format passed into imx_drm_crtc_panel_format*() is the encoder format used for DRM in most cases; the HDMI encoder sets this to none, but this is incorrect, it should be TMDS. Since this is the case, we can pass the drm_encoder structure directly into this function and use the supplied fields there to configure the CRTC.

imx-drm: imx-drm-core: sanitise imx_drm_encoder_get_mux_id() Address the following issues: - imx_drm_encoder_get_mux_id() searches the CRTC list for the matching CRTC, and returns the position within this list as the MUX programming value for encoders. This is sub-optimal for two reasons: 1. It relies upon the CRTC list not changing during the lifetime of the driver. 2. It is dependent on the initialisation order of the CRTCs. We address (1) in this patch, leaving (2) until a better solution can be found, as (2) requires larger changes. - imx_drm_encoder is unused. Instead, pass the drm_encoder which is slightly more useful; all callers pass encoder->crtc as the required crtc, so move this inside the function.
