Subject: [PATCH v7 7/7] arm64: dts: qcom: sc7280: Add DT nodes for the TBUs
Add the device-tree nodes for the TBUs (translation buffer units) that
are present on the sc7280 platforms. The TBUs can be used debug the
kernel and provide additional information when a context faults occur.
Describe all the registers, clocks, interconnects and power-domain
resources that are needed for each of the TBUs.
