[PATCH v3 3/8] arm64: dts: renesas: r9a09g077: Adjust CPG register region sizes

From: Prabhakar

Date: Thu Jul 16 2026 - 08:40:49 EST


From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Increase the size of both CPG register regions from 64 KiB to 128 KiB.

On the RZ/T2H SoC, the CPG/MSSR block is a multi-function block where,
apart from clock and reset handling, it supports other features including
clock monitoring, write protection, and peripheral configuration registers.
Expand the mapped register regions to cover the entire register space of
this block so these additional features can be utilized.
