The PDC driver manages data transfer to and from various offload engines | ||
on some Broadcom SoCs. An SoC may have multiple PDC hardware blocks. There is | ||
one device tree entry per block. | ||
|
||
Required properties: | ||
- compatible : Should be "brcm,iproc-pdc-mbox". | ||
- reg: Should contain PDC registers location and length. | ||
- interrupts: Should contain the IRQ line for the PDC. | ||
- #mbox-cells: 1 | ||
- brcm,rx-status-len: Length of metadata preceding received frames, in bytes. | ||
|
||
Optional properties: | ||
- brcm,use-bcm-hdr: present if a BCM header precedes each frame. | ||
|
||
Example: | ||
pdc0: iproc-pdc0@0x612c0000 { | ||
compatible = "brcm,iproc-pdc-mbox"; | ||
reg = <0 0x612c0000 0 0x445>; /* PDC FS0 regs */ | ||
interrupts = <GIC_SPI 187 IRQ_TYPE_LEVEL_HIGH>; | ||
#mbox-cells = <1>; /* one cell per mailbox channel */ | ||
brcm,rx-status-len = <32>; | ||
brcm,use-bcm-hdr; | ||
}; |
