[PATCH v2 4/8] MIPS: Loongson64: dts: ls7a-pch: Use hex in ranges and reg properties
From: Rong Zhang
Date: Fri Nov 13 2026 - 09:24:22 EST
The ls7a-pch.dtsi mixes two different styles of addresses and sizes.
Some use a all-hex style while some use a semi-dec-semi-hex style.
The latter style is confusing and hard to read, so convent all ranges
and reg properties into the former style.

The following changes will replace ls7a_uart*'s clock-frequency
properties. There are reg properties with the unfavoured style around
the context, so I decided that this series should fix them as well as
other properties for address and size.
