Álvaro Fernández Rojas 8c405cdccc bcm27xx: add 6.6 kernel patches
The patches were generated from the RPi repo with the following command:
git format-patch v6.6.34..rpi-6.1.y

Some patches needed rebasing and, as usual, the applied and reverted, wireless
drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 1057/1085] dts: overlay: ov5647: Specify clock-noncontinuous
on CSI endpoint
The OV5647 declares that it wants a non-continuous clock in its endpoint
configuration. However, it does not expose this information via
get_mbus_config. Even if it would implement get_mbus_config the
bcm2835-unicam driver would not evaluate the flags field of it.
By also specifying clock-noncontinuous on the CSI endpoint itself, the
CSI driver properly picks up the requests and enables the non-continuous
clock mode.
