1 Device tree configuration for Renesas RSPI/QSPI driver
4 - compatible : For Renesas Serial Peripheral Interface on legacy SH:
5 "renesas,rspi-<soctype>", "renesas,rspi" as fallback.
6 For Renesas Serial Peripheral Interface on RZ/A1H:
7 "renesas,rspi-<soctype>", "renesas,rspi-rz" as fallback.
8 For Quad Serial Peripheral Interface on R-Car Gen2:
9 "renesas,qspi-<soctype>", "renesas,qspi" as fallback.
10 Examples with soctypes are:
11 - "renesas,rspi-sh7757" (SH)
12 - "renesas,rspi-r7s72100" (RZ/A1H)
13 - "renesas,qspi-r8a7790" (R-Car H2)
14 - "renesas,qspi-r8a7791" (R-Car M2)
15 - reg : Address start and address range size of the device
16 - interrupts : A list of interrupt-specifiers, one for each entry in
18 If interrupt-names is not present, an interrupt specifier
19 for a single muxed interrupt.
20 - interrupt-names : A list of interrupt names. Should contain (if present):
24 - "mux" for a single muxed interrupt.
25 - interrupt-parent : The phandle for the interrupt controller that
26 services interrupts for this device.
27 - num-cs : Number of chip selects. Some RSPI cores have more than 1.
28 - #address-cells : Must be <1>
29 - #size-cells : Must be <0>
32 - clocks : Must contain a reference to the functional clock.
34 Pinctrl properties might be needed, too. See
35 Documentation/devicetree/bindings/pinctrl/renesas,*.
