    1 * Socionext Synquacer HS-SPI bindings
    2 
    3 Required 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 
   11 Optional 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.
   14 
   15 Example:
   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         };
