Subject: [PATCH v8 7/7] arm64: dts: qcom: sc7280: Add DT nodes for the TBUs
Date: Wed, 17 Apr 2024 06:37:31 -0700
Message-ID: <20240417133731.2055383-8-quic_c_gdjako@quicinc.com>

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.
