From 358032f9a5d76ecf64a52ad5fa189246fd82f834 Mon Sep 17 00:00:00 2001 From: Vignesh Raghavendra Date: Wed, 23 Oct 2019 13:30:02 +0530 Subject: [PATCH] arm: dts: k3-j721e-mcu-wakeup: Add HyperBus Controller node Add DT node for HyperBus Memory Controller in the FSS. On J721e, its not possible to use OSPI0 and HBMC simultaneously as they are muxed within the Flash Subsystem hence disable HBMC by default as keep OSPI enabled. Bootloader will fixup DT when it detects HyperFlash instead of OSPI.
