[Patch v4 1/4] arm64: tegra: Add memory controller channels
From: Ashish Mhetre
Date: Wed Mar 02 2022 - 03:44:36 EST
>From tegra186 onwards, memory controller support multiple channels.
During the error interrupts from memory controller, corresponding
channels need to be accessed for logging error info and clearing the
interrupt.
So add address and size of these channels in device tree node of
tegra186, tegra194 and tegra234 memory controller.
