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.

(*) 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.

drm/connector: Set DDC pointer in drmm_connector_init

Commit 35a3b82 ("drm/connector: Introduce drmm_connector_init")
introduced the function drmm_connector_init() with a parameter for an
optional ddc pointer to the i2c controller used to access the DDC bus.

However, the underlying call to __drm_connector_init() was always
setting it to NULL instead of passing the ddc argument around.

This resulted in unexpected null pointer dereference on platforms
expecting to get a DDC controller.
