Spreadtrum SPI Controller |
|
|
|
Required properties: |
|
- compatible: Should be "sprd,sc9860-spi". |
|
- reg: Offset and length of SPI controller register space. |
|
- interrupts: Should contain SPI interrupt. |
|
- clock-names: Should contain following entries: |
|
"spi" for SPI clock, |
|
"source" for SPI source (parent) clock, |
|
"enable" for SPI module enable clock. |
|
- clocks: List of clock input name strings sorted in the same order |
|
as the clock-names property. |
|
- #address-cells: The number of cells required to define a chip select |
|
address on the SPI bus. Should be set to 1. |
|
- #size-cells: Should be set to 0. |
|
|
|
Optional properties: |
|
dma-names: Should contain names of the SPI used DMA channel. |
|
dmas: Should contain DMA channels and DMA slave ids which the SPI used |
|
sorted in the same order as the dma-names property. |
|
|
|
Example: |
|
spi0: spi@70a00000{ |
|
compatible = "sprd,sc9860-spi"; |
|
reg = <0 0x70a00000 0 0x1000>; |
|
interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>; |
|
clock-names = "spi", "source","enable"; |
|
clocks = <&clk_spi0>, <&ext_26m>, <&clk_ap_apb_gates 5>; |
|
dma-names = "rx_chn", "tx_chn"; |
|
dmas = <&apdma 11 11>, <&apdma 12 12>; |
|
#address-cells = <1>; |
|
#size-cells = <0>; |
|
};
