Hi Greg,
Please consider adding the commits
aeb078cebc40d ("arm64: dts: broadcom: bcm2712-d-rpi-5-b: add fixes for pinctrl/pinctrl_aon")
18d4a06e10051 ("arm64: dts: broadcom: bcm2712-d-rpi-5-b: update uart10 interrupt")
to the stable trees. Without the first, a Raspberry Pi 5 revision D
simply fails to boot, ending rather quickly with a
Kernel panic - not syncing: Asynchronous SError Interrupt
CPU: 2 UID: 0 PID: 1 Comm: swapper/0 Tainted: G M 6.18.29 #1 NONE
Tainted: [M]=MACHINE_CHECK
Hardware name: Raspberry Pi 5 Model B Rev 1.1 (DT)

since the pinctrl register layout is slightly different on that
revision.
For both, a suitable Fixes tag would have been
Fixes: 44839e2ac8ec5 ("arm64: dts: broadcom: Add DT for D-step version of BCM2712")
i.e. this goes back to 6.14, so I suppose that means it is eligible for
6.18.y and 7.0.y. I have tested by applying them on top of v6.18.29.
Thanks,
Rasmus
