[PATCH 4/8] arm64: tegra: Clean up AHUB on Tegra186
From: Thierry Reding
Date: Wed Sep 02 2026 - 06:19:39 EST
From: Thierry Reding <treding@xxxxxxxxxx>
Use #address-cells = <1> and #size-cells = <1> because we don't need
64-bit register addressing for this hardware. While at it, also adjust
the ranges property to encompass the entire AHUB range as per the TRM.
