The controlfb driver has a number of dummy defines for IO operations. They were introduced in commit a07a63b0 ("video: fbdev: controlfb: add COMPILE_TEST support"). The write variants did not use their value parameter in the dummy versions, resulting in set but not used warnings. Fix this by adding "(void)val" to silence the compiler. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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. Let's add a variant structure that will address most of the differences between those three controllers. Reviewed-by:

The DSI clocks setup function has been using an array to store the clock name of either the DSI0 or DSI1 blocks, using the port ID to choose the proper one. Let's switch to an snprintf call to do the same thing and simplify the array a bit. Reviewed-by:

The DSI1_PHY_AFEC0_PD_DLANE1 and DSI1_PHY_AFEC0_PD_DLANE3 register definitions were swapped, so trying to use more than a single data lane failed as lane 1 would get powered down. (In theory a 4 lane device would work as all lanes would remain powered). Correct the definitions. Signed-off-by:

The infoframes are sent at a regular interval as a data island packet, so we don't need to wait for them to be sent when we're setting them up. 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.
