1 The PDC driver manages data transfer to and from various offload engines
2 on some Broadcom SoCs. An SoC may have multiple PDC hardware blocks. There is
3 one device tree entry per block.
6 - compatible : Should be "brcm,iproc-pdc-mbox".
7 - reg: Should contain PDC registers location and length.
8 - interrupts: Should contain the IRQ line for the PDC.
10 - brcm,rx-status-len: Length of metadata preceding received frames, in bytes.
13 - brcm,use-bcm-hdr: present if a BCM header precedes each frame.
