Add support for 24-bit panels that are connected through a 8-bit bus and use delta-RGB, which means a RGB pixel ordering on odd lines, and a GBR pixel ordering on even lines.

The LCD controller expects timing values in dot-clock ticks, which is 3x the timing values in pixels when using a 3x8-bit display; but it will count the display area size in pixels either way.

The job done callback is called from various places, in two ways: in job done role, and as a fence callback role. Essentialize the callback to an atom function to just complete the job, and into a second function as a prototype of fence callback which calls to complete the job. This is used in latter patches by the completion code.

Rename "ring_mirror_list" to "pending_list", to describe what something is, not what it does, how it's used, or how the hardware implements it. This also abstracts the actual hardware implementation, i.e. how the low-level driver communicates with the device it drives, ring, CAM, etc., shouldn't be exposed to DRM. The pending_list keeps jobs submitted, which are out of our control. Usually this means they are pending execution status in hardware, but the latter definition is a more general (inclusive) definition.

Add DP support to display-connector driver. The driver will support HPD via a GPIO and DP PWR. DP PWR will be enabled at probe, which is not optimal, but I'm not sure what would be a good place to enable and disable DP PWR. Perhaps attach/detach, but I don't know if enabling HW is something that attach is supposed to do. In any case, I don't think there's much difference in power consumption between the version in this patch and enabling the regulator later: if the driver probes, supposedly it will attach very soon afterwards, and we need to enable the DP PWR as soon as possible.

Add binding for DisplayPort connector. A few notes: * Similar to hdmi-connector, it has hpd-gpios as an optional property, as the HPD could also be handled by, e.g., the DP bridge. * dp-pwr-supply, which provides 3.3V on DP_PWR pin, is optional, as it is not strictly required: standard DP cables do not even have the pin connected. * Connector type. Full size and mini connectors are identical except for the connector size and form, so I believe there is no functional need for this property. But similar to 'label' property, it might be used to present information about the connector to the userspace. * No eDP. There's really no "eDP connector", as it's always a custom made connection between the DP and the DP panel, although the eDP spec does offer a few suggested pin setups. So possibly there is no need for edp-connector binding, but even if there is, I don't want to guess what it could look like, and could it be part of the dp-connector binding. * No DP++. I'm not familiar with DP++. DP++ might need an i2c bus added to the bindings.

Most of the differences between DSI0 and DSI1 are handled through the ID. However, the BCM2711 DSI is going to introduce one more variable to the mix and will break some expectations of the earlier, simpler, test.

However, we do need to poll when we're enabling since the we can't update the packet RAM until it has been sent. Let's add a boolean flag to tell whether we want to poll or not to support both cases.

The DSI version of the panel behaved instable and close scrutiny of the vendor driver from the Samsung GT-S8190 shows a different initialization sequence for the DSI mode panel than the DPI mode panel. Make the initialization depend on whether we are in DSI or DPI mode and handle the differences. After this the panel on the GT-I8190 becomes much more stable. Also spell out some more custom DCS commands found in the vendor source code to cut down a bit on magic where we can.

This moves the MCDE bindings over to using the YAML schema to describe the ST-Ericsson MCDE display controller, making use of the generic DSI controller schema. In the process we correct an error in the old text bindings: the clocks for the SDI host controllers were specified as part of the main MCDE component while they should be specified in the DSI host controller subnodes. This was a leftover from an earlier iteration of the first patch series adding the MCDE. We also add the "port" node, we will use this when adding LCD panels using the direct parallel interface DPI instead of DSI.

The main problem with this error handling was that it didn't clean up if i2c_add_numbered_adapter() failed. This code is pretty old, and doesn't match with today's checkpatch.pl standards so I took the opportunity to tidy it up a bit. I changed the NULL comparison, and removed the WARNING message if kzalloc() fails and updated the label names.
