1Device-Tree binding for regmap
2
3The endianness mode of CPU & Device scenarios:
4Index Device Endianness properties
5---------------------------------------------------
61 BE 'big-endian'
72 LE 'little-endian'
8
9For one device driver, which will run in different scenarios above
10on different SoCs using the devicetree, we need one way to simplify
11this.
12
13Required properties:
14- {big,little}-endian: these are boolean properties, if absent
15 meaning that the CPU and the Device are in the same endianness mode,
16 these properties are for register values and all the buffers only.
17
18Examples:
19Scenario 1 : CPU in LE mode & device in LE mode.
20dev: dev@40031000 {
21 compatible = "name";
22 reg = <0x40031000 0x1000>;
23 ...
24};
25
26Scenario 2 : CPU in LE mode & device in BE mode.
27dev: dev@40031000 {
28 compatible = "name";
29 reg = <0x40031000 0x1000>;
30 ...
31 big-endian;
32};
33
34Scenario 3 : CPU in BE mode & device in BE mode.
35dev: dev@40031000 {
36 compatible = "name";
37 reg = <0x40031000 0x1000>;
38 ...
39};
40
41Scenario 4 : CPU in BE mode & device in LE mode.
42dev: dev@40031000 {
43 compatible = "name";
44 reg = <0x40031000 0x1000>;
45 ...
46 little-endian;

1Freescale Generic ASoC Sound Card with ASRC support
2
3The Freescale Generic ASoC Sound Card can be used, ideally, for all Freescale
4SoCs connecting with external CODECs.
5
6The idea of this generic sound card is a bit like ASoC Simple Card. However,
7for Freescale SoCs (especially those released in recent years), most of them
8have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And
9this is a specific feature that might be painstakingly controlled and merged
10into the Simple Card.
11
12So having this generic sound card allows all Freescale SoC users to benefit
13from the simplification of a new card support and the capability of the wide
14sample rates support through ASRC.
15
16Note: The card is initially designed for those sound cards who use I2S and
17 PCM DAI formats. However, it'll be also possible to support those non
18 I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as long
19 as the driver has been properly upgraded.
20
21
22The compatible list for this generic sound card currently:
23 "fsl,imx-audio-cs42888"
24
25 "fsl,imx-audio-wm8962"
26 (compatible with Documentation/devicetree/bindings/sound/imx-audio-wm8962.txt)
27
28 "fsl,imx-audio-sgtl5000"
29 (compatible with Documentation/devicetree/bindings/sound/imx-audio-sgtl5000.txt)
30
31Required properties:
32
33 - compatible : Contains one of entries in the compatible list.
34
35 - model : The user-visible name of this sound complex
36
37 - audio-cpu : The phandle of an CPU DAI controller
38
39 - audio-codec : The phandle of an audio codec
40
41 - audio-routing : A list of the connections between audio components.
42 Each entry is a pair of strings, the first being the
43 connection's sink, the second being the connection's
44 source. There're a few pre-designed board connectors:
45 * Line Out Jack
46 * Line In Jack
47 * Headphone Jack
48 * Mic Jack
49 * Ext Spk
50 * AMIC (stands for Analog Microphone Jack)
51 * DMIC (stands for Digital Microphone Jack)
52
53 Note: The "Mic Jack" and "AMIC" are redundant while
54 coexsiting in order to support the old bindings
55 of wm8962 and sgtl5000.
56
57Optional properties:
58
59 - audio-asrc : The phandle of ASRC. It can be absent if there's no
60 need to add ASRC support via DPCM.
61
62Example:
63sound-cs42888 {
64 compatible = "fsl,imx-audio-cs42888";
65 model = "cs42888-audio";
66 audio-cpu = <&esai>;
