The CSC matrices were stored as separate matrix for each colorspace, and if we wanted a limited or full RGB output. This created some gaps in our support and we would not always pick the relevant matrix. Let's rework our data structure to store one per colorspace, and then a matrix for limited range and one for full range. This makes us add a new matrix to support full range BT709 YUV output.

YUV444 and YUV422 actually require the same matrix, but programmed differently. We've dealt with it in the past by having two matrices, with the one for YUV444 reordered to accomodate the hardware. This gets in the way of subsequent reworks so let's define a function that will take the coefficients swap into account, and remove the now redundant YUV444 matrix. Signed-off-by:

The VC4 HDMI driver has a helper function to figure out whether full range or limited range RGB is being used called vc4_hdmi_is_full_range_rgb(). We'll need it to support other colorspaces, so let's rename it to vc4_hdmi_is_full_range(). Signed-off-by:

On VC4, the TV margins on the HDMI connector are implemented by scaling the planes. However, if only the TV margins or the connector are changed by a new state, the planes ending up on that connector won't be. Thus, they won't be updated properly and we'll effectively ignore that change until the next commit affecting these planes. Let's make sure to add all the planes attached to the connector so that we can update them properly. Reviewed-by:

container_of_const() allows to preserve the pointer constness and is thus more flexible than inline functions. Let's switch all our instances of container_of() to container_of_const(). Reviewed-by:

Currently, the pixel conversion functions repeat the same loop to iterate the rows. Instead of repeating the same code for each pixel format, create a function to wrap the loop and isolate the pixel conversion functionality. Suggested-by:

Move code from ad-hoc fbdev callbacks into DRM client functions and remove the old callbacks. The functions instruct the client to poll for changed output or restore the display. The DRM core calls both, the old callbacks and the new client helpers, from the same places. The new functions perform the same operation as before, so there's no change in functionality. Replace all code that initializes or releases fbdev emulation throughout the driver. Instead initialize the fbdev client by a single call to armada_fbdev_setup() after armada has registered its DRM device. As in most drivers, aramda's fbdev emulation now acts like a regular DRM client. The fbdev client setup consists of the initial preparation and the hot-plugging of the display. The latter creates the fbdev device and sets up the fbdev framebuffer. The setup performs display hot-plugging once. If no display can be detected, DRM probe helpers re-run the detection on each hotplug event. A call to drm_dev_unregister() releases the client automatically. No further action is required within armada. If the fbdev framebuffer has been fully set up, struct fb_ops.fb_destroy implements the release. For partially initialized emulation, the fbdev client reverts the initial setup. Signed-off-by:

This bridge doesn't actually implement HPD due to it being way too slow but instead expects the panel driver to wait enough to assume HPD is asserted. However some panels (such as the generic 'edp-panel') expect the bridge to deal with the delay and pass maximum delay to the aux instead. In order to support such panels, add a dummy implementation of wait that would just sleep the maximum delay and assume no failure has happened. Signed-off-by:
