Kernel-4.18.0-80.el8_spi-sun4i

Allwinner A10 SPI controller

Required properties:

• compatible: Should be “allwinner,sun4-a10-spi”.
• reg: Should contain register location and length.
• interrupts: Should contain interrupt.
• clocks: phandle to the clocks feeding the SPI controller. Two are

      needed:
  

  • “ahb”: the gated AHB parent clock
  • “mod”: the parent module clock
• clock-names: Must contain the clock names described just above

Example:

spi1: spi@1c06000 {
compatible = “allwinner,sun4i-a10-spi”;
reg = <0x01c06000 0x1000>;
interrupts = <11>;
clocks = <&ahb_gates 21>, <&spi1_clk>;
clock-names = “ahb”, “mod”;
#address-cells = <1>;
#size-cells = <0>;
};
