From 0979c0069cb669528d13818410de9f0dd41585f3 Mon Sep 17 00:00:00 2001 From: Vaishnav Achath Date: Sat, 13 May 2023 18:03:11 +0530 Subject: arm64: dts: ti: k3-j721e-som-p0: Add HyperFlash node J721E SoM has a HyperFlash and HyperRam connected to HyperBus memory controller, add corresponding node, pinmux and partitions for the same. HyperBus is muxed with OSPI and only one controller can be active at a time, therefore keep HyperBus node disabled. Bootloader will detect the external mux state through a wkup gpio and enable the node as required.
