1 | Freescale Enhanced Serial Audio Interface (ESAI) Controller | ||
2 | |||
3 | The Enhanced Serial Audio Interface (ESAI) provides a full-duplex serial port | ||
4 | for serial communication with a variety of serial devices, including industry | ||
5 | standard codecs, Sony/Phillips Digital Interface (S/PDIF) transceivers, and | ||
6 | other DSPs. It has up to six transmitters and four receivers. | ||
7 | |||
8 | Required properties: | ||
9 | |||
10 | - compatible : Compatible list, must contain "fsl,imx35-esai". | ||
11 | |||
12 | - reg : Offset and length of the register set for the device. | ||
13 | |||
14 | - interrupts : Contains the spdif interrupt. | ||
15 | |||
16 | - dmas : Generic dma devicetree binding as described in | ||
17 | Documentation/devicetree/bindings/dma/dma.txt. | ||
18 | |||
19 | - dma-names : Two dmas have to be defined, "tx" and "rx". | ||
20 | |||
21 | - clocks: Contains an entry for each entry in clock-names. | ||
22 | |||
23 | - clock-names : Includes the following entries: | ||
24 | "core" The core clock used to access registers | ||
25 | "extal" The esai baud clock for esai controller used to derive | ||
26 | HCK, SCK and FS. | ||
27 | "fsys" The system clock derived from ahb clock used to derive | ||
28 | HCK, SCK and FS. | ||
29 | |||
30 | - fsl,fifo-depth: The number of elements in the transmit and receive FIFOs. | ||
31 | This number is the maximum allowed value for TFCR[TFWM] or RFCR[RFWM]. | ||
32 | |||
33 | - fsl,esai-synchronous: This is a boolean property. If present, indicating | ||
34 | that ESAI would work in the synchronous mode, which means all the settings | ||
35 | for Receiving would be duplicated from Transmition related registers. | ||
36 | |||

46 | dma-names = "rx", "tx"; | ||
