Cvitek sysDMA remap driver
|
|
|
|
This document describes the binding for Cvitek sysDMA remap register.
|
|
|
|
Required properties:
|
|
- compatible: "cvitek,sysdma_remap"
|
|
- reg: sysDMA remap register regions
|
|
- ch-remap: assign device for each sysDMA remap channel.
|
|
There are maximum 16 channels can be assigned to remap register.
|
|
But be noted that sysDMA can only support 8 channels at one time.
|
|
|
|
|
|
Example:
|
|
sysdma_remap {
|
|
compatible = "cvitek,sysdma_remap";
|
|
reg = <0x0 0x03000154 0x0 0x10>;
|
|
ch-remap = <CVI_I2S0_RX CVI_I2S0_TX CVI_I2S1_RX CVI_I2S1_TX
|
|
CVI_SPI_NAND CVI_SPI_NAND CVI_I2S3_RX CVI_I2S3_TX>;
|
|
}; |
