Subject: [PATCH v2 0/4] Add support for QoS configuration

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).

Changes in v2:
 - Updated regmap_update to make use GENMASK and FIELD_PREP.
 - Removed the regmap structure from qcom_icc_node.
 - Made qcom_icc_rpmh_configure_qos() static
 - Removed qcom_icc_rpmh_map() API, inlined the code in probe
   function.
 - Updated declarations to reverse christmas tree fashion.

Odelu Kukatla (4):
  interconnect: qcom: icc-rpmh: Add QoS configuration support
  interconnect: qcom: sc7280: enable QoS configuration
  dt-bindings: interconnect: add clock property to configure QoS on
    SC7280
  arm64: dts: qcom: sc7280: Add clocks for QoS configuration
