From 54a85e09f44c5fa322a2d186f50862d09f517225 Mon Sep 17 00:00:00 2001 From: Ashish Mhetre Date: Fri, 6 May 2022 15:23:12 +0200 Subject: memory: tegra: Add MC error logging on Tegra186 onward Add support for logging memory controller errors on Tegra186, Tegra194 and Tegra234. On these SoCs, interrupts can occur on multiple channels. Add support required to read the status of interrupts across multiple channels, log and clear them. Also add new interrupts supported on these SoCs.
