2ea9ec5d2c drm/vc4: hdmi: use drm_atomic_helper_connector_hdmi_hotplug()
Use the helper function to update the connector's information. This
makes sure that HDMI-related events are handled in a generic way.
Currently it is limited to the HDMI state reporting to the sound system.

b4fa080076 drm/vc4: hdmi: stop rereading EDID in get_modes()
The vc4_hdmi_connector_detect_ctx() via vc4_hdmi_handle_hotplug()
already reads EDID and propagates it to the drm_connector. Stop
rereading EDID as a part of the .get_modes() callback and just update
the list of modes. This matches the behaviour of the i915 driver.

e70140ba0d Get rid of 'remove_new' relic from platform driver struct
The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.

e511f8fc3b drm/vc4: Drop planes that are completely off-screen or 0 crtc size
It is permitted for a plane to be configured such that none
of it is on-screen via either negative dest rectangle X,Y
offset, or an offset that is greater than the crtc dimensions.

These planes were resized via drm_atomic_helper_check_plane_state
such that the source rectangle had a zero width or height, but
they still created a dlist entry even though they contributed
no pixels. In the case of vc6_plane_mode_set, that it could result
in negative values being written into registers, which caused
incorrect behaviour.

Drop planes that result in a source width or height of 0 pixels
or an on-screen size of 0 pixels to avoid the incorrect rendering.

52b0a07316 drm/vc4: Enable bg_fill if there are no planes enabled
The default was to have enable_bg_fill disabled and the first
plane set it if it wasn't opaque and covering the whole screen.
However that meant that if no planes were enabled, then the
background fill wasn't enabled, and would give a striped
output from the uninitialised output buffer.

Initialise it to enabled to avoid this.

drm/vc4: Stop the active perfmon before being destroyed
Upon closing the file descriptor, the active performance monitor is not
stopped. Although all perfmons are destroyed in `vc4_perfmon_close_file()`,
the active performance monitor's pointer (`vc4->active_perfmon`) is still
retained.

If we open a new file descriptor and submit a few jobs with performance
monitors, the driver will attempt to stop the active performance monitor
using the stale pointer in `vc4->active_perfmon`. However, this pointer
is no longer valid because the previous process has already terminated,
and all performance monitors associated with it have been destroyed and
freed.

To fix this, when the active performance monitor belongs to a given
process, explicitly stop it before destroying and freeing it.

	if (condition)
	  // stop channel
to
	if (condition)
	  goto out
	//stop channel
	out:
and also changed the exact register writes used to stop the channel.

Correct the logic so that the channel is actually stopped, and revert
to the original register writes.

8e7eb0c54a drm/vc4: plane: Move the buffer offset out of the vc4_plane_state
The offset fields in vc4_plane_state are described as being
the offset for each buffer in the bo, however it is used to
store the complete DMA address that is then written into the
register.

The DMA address including the fb ofset can be retrieved
using drm_fb_dma_get_gem_addr, and the offset adjustment due to
clipping is local to vc4_plane_mode_set.
Drop the offset field from the state, and compute the complete
DMA address in vc4_plane_mode_set.

7621db4d40 drm/vc4: hvs: Change prototype of __vc4_hvs_alloc to pass registers
The BCM2712 HVS has registers to report the size of the various SRAM the
driver uses, and their size actually differ depending on the stepping.

The initialisation of the memory pools happen in the __vc4_hvs_alloc()
function that also allocates the main HVS structure, that will then hold
the pointer to the memory mapping of the registers.

This creates some kind of circular dependency that we can break by
passing the mapping pointer as an argument for __vc4_hvs_alloc() to use
to query to get the SRAM sizes and initialise the memory pools
accordingly.

74c3b7c63b drm/vc4: hvs: Rework LBM alignment
With the introduction of the support for BCM2712, the check of whether
we're running on vc5 or not to compute the LBM alignment requirement
doesn't work anymore.

Moreover, the LBM size will need to be computed in words for the
BCM2712, while we've had sizes in bytes so far.

Aligning on either 64 or 32 words is thus fairly harmful on BCM2712, so
let's just explicitly align the size when needed, and then call
drm_mm_insert_node_generic() with an alignment of 1.
