Subject: [PATCH v3 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 v3:
 - Skip QoS programming incase regmap failse and continue with probe.
 - Defined all the qos structures as const.
 - Fixed compilation issue occurring with arm-linux-gnueabi- toolchain.
 - Removed enable_qos_deps() and disable_qos_deps() as no explicit
   voting is needed for BCM before sync_state.

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