+Device Tree Clock bindings for ATL (Audio Tracking Logic) of DRA7 SoC.
+
+The ATL IP is used to generate clock to be used to synchronize baseband and
+audio codec. A single ATL IP provides four ATL clock instances sharing the same
+functional clock but can be configured to provide different clocks.
+ATL can maintain a clock averages to some desired frequency based on the bws/aws
+signals - can compensate the drift between the two ws signal.
+
+In order to provide the support for ATL and it's output clocks (which can be used
+internally within the SoC or external components) two sets of bindings is needed:
+
+Clock tree binding:
+This binding uses the common clock binding[1].
+To be able to integrate the ATL clocks with DT clock tree.
+Provides ccf level representation of the ATL clocks to be used by drivers.
+Since the clock instances are part of a single IP this binding is used as a node
+for the DT clock tree, the IP driver is needed to handle the actual configuration
+of the IP.

+Required properties:
+- compatible : shall be "ti,dra7-atl-clock"
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles to functional clock of ATL
+
+Binding for the IP driver:
+This binding is used to configure the IP driver which is going to handle the
+configuration of the IP for the ATL clock instances.
+
+Required properties:
+- compatible : shall be "ti,dra7-atl"

+- clocks : link phandles to functional clock of ATL
