Subject: [PATCH v2 6/6] arm64: dts: qcom: sdm845: Add DT nodes for the TBUs
Date:   Fri, 17 Nov 2023 20:27:30 -0800
Message-ID: <20231118042730.2799-7-quic_c_gdjako@quicinc.com>
In-Reply-To: <20231118042730.2799-1-quic_c_gdjako@quicinc.com>

Precedence: bulk

Add the device-tree nodes for the TBUs (translation buffer units) that
are present on the sdm845 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.
