Subject: arm64: dts: qcom: sdm630: set adsp compute-cbs' regs properly
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=e8e1fb5c703fc6962103ffdc60830df99351c139;p=thirdparty%2Fkernel%2Flinux.git

arm64: dts: qcom: sdm630: set adsp compute-cbs' regs properly

Changing FastRPC compute-cbs' reg values to matching iommu streams
solves SMMU translation errors when trying to use FastRPC on ADSP
so change FastRPC compute-cbs' reg values that way
