Subject: dt-bindings: interconnect: qcom,qcs8300-rpmh: add clocks property to enable QoS
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=28a70e793977a606395550b3c0547c14b6441e98;p=thirdparty%2Flinux.git

dt-bindings: interconnect: qcom,qcs8300-rpmh: add clocks property to enable QoS

Some QCS8300 interconnect nodes have QoS registers located inside
a block whose interface is clock-gated. For those nodes, driver
must enable the corresponding clock(s) before accessing the
registers. Add the 'clocks' property so the driver can obtain
and enable the required clock(s).

Only interconnects that have clock‑gated QoS register interface
use this property; it is not applicable to all interconnect nodes.
