1 | NVIDIA Tegra30 AHUB (Audio Hub) | ||
2 | |||
3 | Required properties: | ||
4 | - compatible : "nvidia,tegra30-ahub" | ||
5 | - reg : Should contain the register physical address and length for each of | ||
6 | the AHUB's APBIF registers and the AHUB's own registers. | ||
7 | - interrupts : Should contain AHUB interrupt | ||
8 | - nvidia,dma-request-selector : The Tegra DMA controller's phandle and | ||
9 | request selector for the first APBIF channel. | ||
10 | - ranges : The bus address mapping for the configlink register bus. | ||
11 | Can be empty since the mapping is 1:1. | ||
12 | - #address-cells : For the configlink bus. Should be <1>; | ||
13 | - #size-cells : For the configlink bus. Should be <1>. | ||
14 | |||
15 | AHUB client modules need to specify the IDs of their CIFs (Client InterFaces). | ||
16 | For RX CIFs, the numbers indicate the register number within AHUB routing | ||
17 | register space (APBIF 0..3 RX, I2S 0..5 RX, DAM 0..2 RX 0..1, SPDIF RX 0..1). | ||
18 | For TX CIFs, the numbers indicate the bit position within the AHUB routing | ||
19 | registers (APBIF 0..3 TX, I2S 0..5 TX, DAM 0..2 TX, SPDIF TX 0..1). | ||
20 | |||
21 | Example: | ||
22 | |||
23 | ahub@70080000 { | ||
24 | compatible = "nvidia,tegra30-ahub"; | ||
25 | reg = <0x70080000 0x200 0x70080200 0x100>; | ||
26 | interrupts = < 0 103 0x04 >; | ||
27 | nvidia,dma-request-selector = <&apbdma 1>; | ||
28 | |||
29 | ranges; | ||

31 | #size-cells = <1>; | ||
