configs: Really enable Hailo accelerator driver

For real, this time.

dts: bcm2712: cm5: Force the ANT pins to GPIOs

The magic required to make requesting a GPIO automatically change the
pinmux settings is currently absent. Work around that by explicitly
requesting that the ANT pins be in GPIO mode.

drm/vc4: Fix atomic_async_check to call the right mode_set function

vc4_plane_atomic_async_check was always calling vc4_plane_mode_set
to validate and generate the dlist for the check. If async_check
decided it had to fall back to a sync commit, then this GEN4/5
dlist could get used on GEN6.

Call either vc4_plane_mode_set or vc6_plane_mode_set as appropriate.

drm: vc4: Block swiotlb bounce buffers being imported as dmabuf

The dmabuf import already checks that the backing buffer is contiguous
and rejects it if it isn't. vc4 also requires that the buffer is
in the bottom 1GB of RAM, and this is all correctly defined via
dma-ranges.

However the kernel silently uses swiotlb to bounce dma buffers
around if they are in the wrong region. This relies on dma sync
functions to be called in order to copy the data to/from the
bounce buffer.

DRM is based on all memory allocations being coherent with the
GPU so that any updates to a framebuffer will be acted on without
the need for any additional update. This is fairly fundamentally
incompatible with needing to call dma_sync_ to handle the bounce
buffer copies, and therefore we have to detect and reject mappings
that use bounce buffers.

drivers: media: imx477: Set horizontal binning when disabling the scaler

The horizontal scaler has been disabled but actually the sensor is not
binning horizontally, resulting in images that are stretched 2x
horizontally (missing the right half of the field of view completely).

Therefore we must additionally set the horizontal binning mode. There
is only marginal change in output quality and noise levels.

fixup! overlays: mcp23017: allow specification of the i2c bus

The incorrect fragment order (*) caused broke the interrupt usage, and
while it was being fixed the lack of a reference to the pinctrl
declaration was noticed.

See: #5677

(*) Ideally all fragments would appear in the file in the order in which
they should be merged, but that is easy to forget and can be awkward, so
the firmware merges all "intra" fragments (those that target other
fragments in the overlay) before "inter" fragments (those that target
the base DTB). However, intra fragments that target other intra
fragments is a level of nesting too far for this logic to cope, so they
must appear before the fragments they target.

vc4/drm: Remove the clear of SCALER_DISPBKGND_FILL

Since "drm/vc4: hvs: Support BCM2712 HVS" booting Pi4
with dual 4kp30 displays connected fails with:
vc4-drm gpu: [drm] *ERROR* [CRTC:107:pixelvalve-4] flip_done timed out

It has been tracked down to the referenced commit adding a
path to clear the SCALER_DISPBKGND_FILL when not required.

Dual 4kp30 works with a core clock of 297MHz when background fill
is enabled, but requires a higher value with it disabled.
320MHz still fails, while 330MHz seems okay.

Lets always enable background fill for Pi0-4.

fixup! gpio-fsm: Avoid truncation of delay jiffies

The kernel's time unit of jiffies should be stored as an unsigned long
value. Storing it as an unsigned int, as gpio-fsm did, leads to
truncation and malfunction when the kernel is built for a 64-bit
platform.

media: imx219: Advertise embedded data node on media pad 1

This commit updates the imx219 driver to adverise support for embedded
data streams.  This can then be used by the bcm2835-unicam driver, which
has recently been updated to expose the embedded data stream to
userland.

The imx219 sensor subdevice overloads the media pad to differentiate
between image stream (pad 0) and embedded data stream (pad 1) when
performing the v4l2_subdev_pad_ops functions.

imx708: Do not reset vblank to a default value

imx708_set_framing_limits resets the vblank control to the mode default
value unconditionally. This causes it to overwrite the user specified
vblank and exposure control values when starting the sensor, since
it is called when handling V4L2_CID_WIDE_DYNAMIC_RANGE.

Remove this call to s_ctrl as it is unnecessary.
