Subject: [PATCH v2 11/11] dt-bindings: slimbus: qcom,slim-ngd: convert to DT schema
Date: Wed, 28 Sep 2022 17:20:27 +0200 [thread overview]
Message-ID: <20220928152027.489543-12-krzysztof.kozlowski@linaro.org> (raw)
In-Reply-To: <20220928152027.489543-1-krzysztof.kozlowski@linaro.org>
Convert the Qualcomm SoC SLIMBus Non Generic Device (NGD) controller
bindings to DT Schema.
During conversion add iommus already present in DTS and extend the
example based on SDM845.
