1* Socionext Synquacer HS-SPI bindings
2
3Required Properties:
4- compatible: should be "socionext,synquacer-spi"
5- reg: physical base address of the controller and length of memory mapped
6 region.
7- interrupts: should contain the "spi_rx", "spi_tx" and "spi_fault" interrupts.
8- clocks: core clock iHCLK. Optional rate clock iPCLK (default is iHCLK)
9- clock-names: Shall be "iHCLK" and "iPCLK" respectively
10
11Optional Properties:
12- socionext,use-rtm: boolean, if required to use "retimed clock" for RX
13- socionext,set-aces: boolean, if same active clock edges field to be set.

15Example:
16
17 spi0: spi@ff110000 {
18 compatible = "socionext,synquacer-spi";
19 reg = <0xff110000 0x1000>;
20 interrupts = <GIC_SPI 160 IRQ_TYPE_LEVEL_HIGH>,
21 <GIC_SPI 161 IRQ_TYPE_LEVEL_HIGH>,
22 <GIC_SPI 162 IRQ_TYPE_LEVEL_HIGH>;
23 clocks = <&clk_hsspi>;
24 clock-names = "iHCLK";
25 socionext,use-rtm;
26 socionext,set-aces;
27 };
