* NVIDIA Tegra Hardware Synchronization Primitives (HSP) bindings
|
|
|
|
Tegra HSP unit is designed to support synchronization among processors on the
|
|
SoC for various tasks where shared resources need to be accessed exclusively
|
|
or inter-processor communications support.
|
|
|
|
Required properties:
|
|
|
|
- compatible: should be "nvidia,tegra186-hsp"
|
|
|
|
- reg: base address and length of the HSP aperture
|
|
|
|
- interrupts: interrupts corresponding to interrupt-names
|
|
|
|
- interrupt-names: where applicable:
|
|
- "doorbell": CPU doorbell interrupt
|
|
- "sharedN": shared interrupt number N (N in 0..7)
|
|
- "emptyN": mailbox number N empty interrupt (N in 0..7)
|
|
- "fullN": mailbox number N full interrupt (N in 0..7)
|
|
|
|
- nvidia,doorbell: doorbell identifier of the local doorbell
|
|
|
|
- nvidia,mbox-ie: if present, enable and disable all mbox interrupts
|
|
using mbox-specific registers
|
|
|
|
Symbolic doorbell constants are defined in:
|
|
<dt-bindings/platform/t186/tegra-hsp.h>
