* 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 */
};
