Kernel-3.10.0-957.el7_brcm,bcm2835-spi

Broadcom BCM2835 SPI0 controller

The BCM2835 contains two forms of SPI master controller, one known simply as
SPI0, and the other known as the “Universal SPI Master”; part of the
auxilliary block. This binding applies to the SPI0 controller.

Required properties:

  • compatible: Should be “brcm,bcm2835-spi”.
  • reg: Should contain register location and length.
  • interrupts: Should contain interrupt.
  • clocks: The clock feeding the SPI controller.

Example:

spi@20204000 {
compatible = “brcm,bcm2835-spi”;
reg = <0x7e204000 0x1000>;
interrupts = <2 22>;
clocks = <&clk_spi>;
#address-cells = <1>;
#size-cells = <0>;
};
