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 0637/1085] drm/panel: waveshare: Fix up timings for 10.1"
panel
The 10.1" panel doesn't work with the timings defined. vc4
will always have been fixing up the timing due to the limited
integer divider, so compute the fixed up mode and use it
directly.
