[PATCH v4 10/10] arm64: dts: qcom: sc7280: Add DT nodes for the TBUs

From: Georgi Djakov
Date: Thu Feb 01 2024 - 16:08:26 EST


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 the all registers, clocks, interconnects and power-domain
resources that are needed for each of the TBUs.
