[PATCH v2 0/2] arm64: dts: meson-gxbb-odroidc2: eFuse MAC address and LED properties

[Fil Dunsky via B4 Relay <devnull+filipp.dunsky.gmail.com@kernel.org>]

Two small device-tree updates for the Hardkernel ODROID-C2, found while
adding OpenWrt support for the board.

Patch 1 wires the eth_mac eFuse nvmem cell (already described in
meson-gx.dtsi, but so far unused) to the Ethernet controller, narrowed
to the 6 bytes of the address, so the kernel reads the factory MAC
address itself instead of relying on the bootloader or a random
fallback.

Patch 2 converts the blue status LED to the standard color/function
properties.

Both verified on ODROID-C2 hardware and rechecked against this tree
with CHECK_DTBS=y W=1.

Changes in v2:
- Patch 1: narrow the eth_mac cell to 6 bytes for this board.  The
  16-byte cell from meson-gx.dtsi is rejected by
  of_get_mac_address_nvmem(), so v1 only appeared to work because the
  bootloader had already fixed up local-mac-address.  Reported by the
  Sashiko AI review.
- Patch 1: describe the actual test setup in the commit message.
- Link to v1: https://patch.msgid.link/20261011-odroidc2-dts-v1-0-f9f0e779af88@gmail.com
