operating-system/buildroot-external/board/raspberrypi/yellow/patches/linux/0001-ARM-dts-bcm2711-Add-device-tree-for-Home-Assistant-Y.patch
Jan Čermák c6338f1576 Update RPi kernel to 6.12.20 (#4036) 
* Update RPi kernel to 6.12.20

Update to latest stable RPi kernel and remove unnecessary 6.6.y kernel config
fragments.

* Refresh RPi and Yellow patches

Rebase all patches on 6.12.20, remove patches that are already present
upstream.

* Update Yellow device trees for 6.12.20

Upstream changes broke our downstream device trees. While the CM4 fix was
trivial, there were more changes in the CM5 device tree due to adaptation to
upstream code. To simplify future maintenance, DTS was refactored to reuse CM5
DTS include and override only what's necessary.

* Bump buildroot to update to matching package/rpi-firmware

* buildroot ead21eb6d2...cd82256125 (1):
  > package/rpi-firmware: bump version to f49a396 (1.20250326)
