Kernel-4.18.0-80.el8_atmel-quadspi

• Atmel Quad Serial Peripheral Interface (QSPI)

Required properties:

• compatible: Should be “atmel,sama5d2-qspi”.
• reg: Should contain the locations and lengths of the base registers

              and the mapped memory.
  

• reg-names: Should contain the resource reg names:

              - qspi_base: configuration register address space
              - qspi_mmap: memory mapped address space
  

• interrupts: Should contain the interrupt for the device.
• clocks: The phandle of the clock needed by the QSPI controller.
• #address-cells: Should be <1>.
• #size-cells: Should be <0>.

Example:

spi@f0020000 {
compatible = “atmel,sama5d2-qspi”;
reg = <0xf0020000 0x100>, <0xd0000000 0x8000000>;
reg-names = “qspi_base”, “qspi_mmap”;
interrupts = <52 IRQ_TYPE_LEVEL_HIGH 7>;
clocks = <&spi0_clk>;
#address-cells = <1>;
#size-cells = <0>;
pinctrl-names = “default”;
pinctrl-0 = <&pinctrl_spi0_default>;
