- Bindings for the Cadence Xtensa Remote Processing HW-specific driver for
- HiKey960.
- This binding is an extension of the cdns,xrp,v1 binding. All properties of
- that binding are in effect.
- Required properties:
- - compatible: shall be "cdns,xrp-hw-hikey960,v1".
- - reg: register locations of the DSP shared memory (first entry, same as in
- cdns,xrp,v1) panic/log buffer location (second entry, optional).
- Optional properties:
- - device-irq: 1 32-bit cell: DSP IRQ number (normal core IRQ number, not
- external IRQ number) assigned to the egress mailbox.
- - host-irq: 1 32-bit cell, when present enables IRQ usage in DSP->host
- direction.
- Example:
- xrp@0 {
- #address-cells = <1>;
- #size-cells = <1>;
- compatible = "cdns,xrp-hw-simple,v1";
- reg = <
- 0x0 0x8b301000 0x0 0x0037f000 /* Shared memory */
- 0x0 0x8b300000 0x0 0x00001000 /* Panic/log page */
- >;
- device-irq = <3>;
- host-irq = <0>;
