Merge branch 'icc-rpmh-qos' into icc-next
This series adds QoS support for QNOC type device which can be found on SC7280 platform. It adds support for programming priority, priority forward disable and urgency forwarding. This helps in priortizing the traffic originating from different interconnect masters at NOC (Network On Chip). * icc-rpmh-qos dt-bindings: interconnect: add clock property to enable QOS on SC7280 interconnect: qcom: icc-rpmh: Add QoS configuration support interconnect: qcom: sc7280: enable QoS configuration interconnect: qcom: Fix DT backwards compatibility for QoS Link: https://lore.kernel.org/r/20240607173927.26321-1-quic_okukatla@quicinc.com Signed-off-by: Georgi Djakov <djakov@kernel.org>
