17 When compatible with the generic version, nodes
18 must list the SoC-specific version corresponding
19 to the platform first followed by the generic
22 - reg : A list of offsets and lengths of the register sets for
24 If only one register set is present, it is to be used
25 by both the CPU and the DMA engine.
26 If two register sets are present, the first is to be
27 used by the CPU, and the second is to be used by the
29 - interrupt-parent : The phandle for the interrupt controller that
30 services interrupts for this device
31 - interrupts : Interrupt specifier
32 - #address-cells : Must be <1>
33 - #size-cells : Must be <0>
36 - clocks : Must contain a reference to the functional clock.
37 - num-cs : Total number of chip-selects (default is 1)
38 - dmas : Must contain a list of two references to DMA
39 specifiers, one for transmission, and one for
41 - dma-names : Must contain a list of two DMA names, "tx" and "rx".
42 - spi-slave : Empty property indicating the SPI controller is used
44 - renesas,dtdl : delay sync signal (setup) in transmit mode.
45 Must contain one of the following values:
47 50 (0.5-clock-cycle delay)
48 100 (1-clock-cycle delay)
49 150 (1.5-clock-cycle delay)
50 200 (2-clock-cycle delay)
