Subject: arm: dts: k3-j721e-mcu-wakeup: Add HyperBus Controller node
X-Git-Tag: v2022.10~89^2~22^2~33
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=297daac43afb9c2a1d8876803ff6e4739bef1e13;p=platform%2Fkernel%2Fu-boot.git

arm: dts: k3-j721e-mcu-wakeup: Add HyperBus Controller node

Add DT node for HyperBus Memory Controller and hbmc-mux in the
FSS. hbmc-am654 driver uses syscon_get_regmap() call which fails
with current compatible setting.
