+* Texas Instruments DRA7 Audio Tracking Logic (ATL)
+
+Required properties:
+- compatible: "ti,dra7-atl"
+- ti,hwmods: Name of the hwmod associated with the ATL module
+
+
+Optional properties:
+- ti,atclk<n>-freq: Output clock frequency for ATL instance n.
+                ATL instance is disabled if this property is not set
+- ti,atl<n>-bws-input: ATL baseband word select input for ATL instance n.
+  Possible inputs are:
+         0 - McASP1 FSR
+         1 - McASP1 FSX
+         2 - McASP2 FSR
+         3 - McASP2 FSX
+         4 - McASP3 FSX
+         5 - McASP4 FSX
+         6 - McASP5 FSX
+         7 - McASP6 FSX
+         8 - McASP7 FSX
+         9 - McASP8 FSX
+        10 - McASP8 AHCLKX
+        11 - XREF_CLK3 input pad
+        12 - XREF_CLK0 input pad
+        13 - XREF_CLK1 input pad
+        14 - XREF_CLK2 input pad
+        15 - OSC1_X1 input pad
+- ti,atl<n>-aws-input: Audio word select input for ATL instance n.
+  Same inputs than BWS.
+
+
+Example:
+
+atl: atl@0x4843c000 {
+        compatible = "ti,dra7-atl";
+        reg = <0x4843c000 0x3ff>;
+        ti,hwmods = "atl";
+        ti,atclk1-freq = <11289600>;    /* 11.2896 MHz */
+        ti,atl1-bws-input = <2>;        /* McASP2 FSR */
+        ti,atl1-aws-input = <4>;        /* McASP3 FSX */
+};
