1* Atmel Quad Serial Peripheral Interface (QSPI) 2 3Required properties: 4- compatible: Should be "atmel,sama5d2-qspi". 5- reg: Should contain the locations and lengths of the base registers 6 and the mapped memory. 7- reg-names: Should contain the resource reg names: 8 - qspi_base: configuration register address space 9 - qspi_mmap: memory mapped address space 10- interrupts: Should contain the interrupt for the device. 11- clocks: The phandle of the clock needed by the QSPI controller. 12- #address-cells: Should be <1>. 13- #size-cells: Should be <0>. 14 15Example: 16 17spi@f0020000 { 18 compatible = "atmel,sama5d2-qspi"; 19 reg = <0xf0020000 0x100>, <0xd0000000 0x8000000>; 20 reg-names = "qspi_base", "qspi_mmap"; 21 interrupts = <52 IRQ_TYPE_LEVEL_HIGH 7>; 22 clocks = <&spi0_clk>; 23 #address-cells = <1>; 24 #size-cells = <0>; 25 pinctrl-names = "default"; 26 pinctrl-0 = <&pinctrl_spi0_default>; 27 28 m25p80@0 { 29 ... 30 }; 31}; 32
