5aed213c7c drm/udl: Remove DRM_CONNECTOR_POLL_HPD 
DisplayLink devices do not generate hotplug events. Remove the poll
flag DRM_CONNECTOR_POLL_HPD, as it may not be specified together with
DRM_CONNECTOR_POLL_CONNECT or DRM_CONNECTOR_POLL_DISCONNECT.

a918dcfecc drm/arm/komeda: update DMA mask to 40 bits 
Each layer in the DPU has a 40-bit base address register, which indicates
start of frame buffer data for that layer. Komeda driver does not set
its DMA mask, which makes it 32-bit by default which does not use
the entire available possible supported by the DPU.

Update the DMA mask to align with DPU Architecture v1.0 spec.

71b03802fe drm/arm/komeda: Move pipeline prints to after the entire pipeline has been enabled 
The komeda driver prints a pretty verbose log in komeda_pipeline_dump()
detailing the components of each of the two pipelines. This gets printed
multiple times during boot as komeda EPROBE_DEFERs waiting for the
remote bridge drivers to come up. Move this log to after this has
happened indicating that the printed pipeline is actually completely up.

Since commit 4cfe5cc02e ("drm/arm/komeda: Remove component framework and
add a simple encoder"), the devm_drm_of_get_bridge() call happens
regardless of whether any remote nodes are available on the pipeline. Fix
this by moving the bridge attach to its own function and calling it
conditional on there being an output link.

ed325ac38e drm/arm/komeda: don't use confusing 'timeout' variable name 
There is a confusing pattern in the kernel to use a variable named 'timeout' to
store the result of wait_for_completion_timeout() causing patterns like:

	timeout = wait_for_completion_timeout(...)
	if (!timeout) return -ETIMEDOUT;

with all kinds of permutations. Check the return value directly to drop
'timeout'  which also fixes its wrong type.

7fb8af6798 drm: deprecate driver date 
The driver date serves no useful purpose, because it's hardly ever
updated. The information is misleading at best.

As described in Documentation/gpu/drm-internals.rst:

  The driver date, formatted as YYYYMMDD, is meant to identify the date
  of the latest modification to the driver. However, as most drivers
  fail to update it, its value is mostly useless. The DRM core prints it
  to the kernel log at initialization time and passes it to userspace
  through the DRM_IOCTL_VERSION ioctl.

Stop printing the driver date at init, and start returning the empty
string "" as driver date through the DRM_IOCTL_VERSION ioctl.

The driver date initialization in drivers and the struct drm_driver date
member can be removed in follow-up.

808a40b694 drm/fbdev-dma: Implement damage handling and deferred I/O 
Add support for damage handling and deferred I/O to fbdev-dma. This
enables fbdev-dma to support all DMA-memory-based DRM drivers, even
such with a dirty callback in their framebuffers.

The patch adds the code for deferred I/O and also sets a dedicated
helper for struct fb_ops.fb_mmap that support coherent mappings.

v3:
- init fb_ops with FB_GEN_DEFAULT_DEFERRED_DMAMEM_OPS() (Javier)
