1 Spreadtrum SPI Controller
4 - compatible: Should be "sprd,sc9860-spi".
5 - reg: Offset and length of SPI controller register space.
6 - interrupts: Should contain SPI interrupt.
7 - clock-names: Should contain following entries:
9 "source" for SPI source (parent) clock,
10 "enable" for SPI module enable clock.
11 - clocks: List of clock input name strings sorted in the same order
12 as the clock-names property.
13 - #address-cells: The number of cells required to define a chip select
14 address on the SPI bus. Should be set to 1.
15 - #size-cells: Should be set to 0.
18 dma-names: Should contain names of the SPI used DMA channel.
19 dmas: Should contain DMA channels and DMA slave ids which the SPI used
20 sorted in the same order as the dma-names property.
