* Hisilicon hip07 Security Accelerator (SEC)
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Must contain one of
|
||
|
|
- "hisilicon,hip06-sec"
|
||
|
|
- "hisilicon,hip07-sec"
|
||
|
|
- reg: Memory addresses and lengths of the memory regions through which
|
||
|
|
this device is controlled.
|
||
|
|
Region 0 has registers to control the backend processing engines.
|
||
|
|
Region 1 has registers for functionality common to all queues.
|
||
|
|
Regions 2-18 have registers for the 16 individual queues which are isolated
|
||
|
|
both in hardware and within the driver.
|
||
|
|
- interrupts: Interrupt specifiers.
|
||
|
|
Refer to interrupt-controller/interrupts.txt for generic interrupt client node
|
||
|
|
bindings.
|
||
|
|
Interrupt 0 is for the SEC unit error queue.
|
||
|
|
Interrupt 2N + 1 is the completion interrupt for queue N.
|
||
|
|
Interrupt 2N + 2 is the error interrupt for queue N.
|
||
|
|
- dma-coherent: The driver assumes coherent dma is possible.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- iommus: The SEC units are behind smmu-v3 iommus.
|
||
|
|
Refer to iommu/arm,smmu-v3.txt for more information.
