Fix typos and add the following to the scripts/spelling.txt: followings||following While we are here, add a missing colon in the boilerplate in DT binding documents. The "you SoC" in allwinner,sunxi-pinctrl.txt was fixed as well. I reworded "as the followings:" to "as follows:" for drivers/usb/gadget/udc/renesas_usb3.c.

|
|
|
|
Required properties:
|
|
- compatible: must be one of the following compatibles:
|
|
- "allwinner,sun4i-a10-codec"
|
|
- "allwinner,sun6i-a31-codec"
|
|
- "allwinner,sun7i-a20-codec"
|
|
- "allwinner,sun8i-a23-codec"
|
|
- "allwinner,sun8i-h3-codec"
|
|
- reg: must contain the registers location and length
|
|
- interrupts: must contain the codec interrupt
|
|
- dmas: DMA channels for tx and rx dma. See the DMA client binding,
|
|
Documentation/devicetree/bindings/dma/dma.txt
|
|
- dma-names: should include "tx" and "rx".
|
|
- clocks: a list of phandle + clock-specifer pairs, one for each entry
|
|
in clock-names.
|
|
- clock-names: should contain the following:
|
|
- "apb": the parent APB clock for this controller
|
|
- "codec": the parent module clock
|
|
|
|
Optional properties:
|
|
- allwinner,pa-gpios: gpio to enable external amplifier
|
|
|
|
Required properties for the following compatibles:
|
|
- "allwinner,sun6i-a31-codec"
|
|
- "allwinner,sun8i-a23-codec"
|
|
- "allwinner,sun8i-h3-codec"
|
|
- resets: phandle to the reset control for this device
|
|
- allwinner,audio-routing: A list of the connections between audio components.
|
|
Each entry is a pair of strings, the first being the
|
|
connection's sink, the second being the connection's
|
|
source. Valid names include:
|
|
|
|
Audio pins on the SoC:
|
|
"HP"

|
|
"MIC1"
|
|
"MIC2"
|
|
"MIC3" (sun6i-a31 only)
|
|
|
|
Microphone biases from the SoC:
|
|
"HBIAS"
|
|
"MBIAS"
|
|
|
|
Board connectors:
|
|
"Headphone"
|
|
"Headset Mic"
|
|
"Line In"
|
|
"Line Out"
|
|
"Mic"
|
|

|
|
block in the PRCM.
