-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@...00000{
- 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>;
-};
