1IMG Synchronous Peripheral Flash Interface (SPFI) controller 2 3Required properties: 4- compatible: Must be "img,spfi". 5- reg: Must contain the base address and length of the SPFI registers. 6- interrupts: Must contain the SPFI interrupt. 7- clocks: Must contain an entry for each entry in clock-names. 8 See ../clock/clock-bindings.txt for details. 9- clock-names: Must include the following entries: 10 - spfi: SPI operating clock 11 - sys: SPI system interface clock 12- dmas: Must contain an entry for each entry in dma-names. 13 See ../dma/dma.txt for details. 14- dma-names: Must include the following entries: 15 - rx 16 - tx 17- cs-gpios: Must specify the GPIOs used for chipselect lines. 18- #address-cells: Must be 1. 19- #size-cells: Must be 0. 20 21Optional properties: 22- img,supports-quad-mode: Should be set if the interface supports quad mode 23 SPI transfers. 24- spfi-max-frequency: Maximum speed supported by the spfi block. 25 26Example: 27 28spi@18100f00 { 29 compatible = "img,spfi"; 30 reg = <0x18100f00 0x100>; 31 interrupts = <GIC_SHARED 22 IRQ_TYPE_LEVEL_HIGH>; 32 clocks = <&spi_clk>, <&system_clk>; 33 clock-names = "spfi", "sys"; 34 dmas = <&mdc 9 0xffffffff 0>, <&mdc 10 0xffffffff 0>; 35 dma-names = "rx", "tx"; 36 37 #address-cells = <1>; 38 #size-cells = <0>; 39}; 40
