[PATCH 1/2] riscv: dts: sophgo: sg2044: use hex for CPU unit address

From: Inochi Amaoto

Date: Mon Apr 06 2026 - 19:27:44 EST


Previous the CPU unit address cpu of sg2044 use decimal, it is
not following the general convention for unit addresses of the
OF. Convent the unit address to hex to resolve this problem.

The introduces a small ABI break for the CPU id, but it should
affect nothing since there is no direct full-path reference to
these CPU nodes.

Fixes: 967a94a92aaa ("riscv: dts: add initial Sophgo SG2042 SoC device tree")
