HiSilicon Hip06/Hip07 PCIe host bridge DT (almost-ECAM) description.
|
||||
The properties and their meanings are identical to those described in
|
||||
host-generic-pci.txt except as listed below.
|
||||
|
||||
Properties of the host controller node that differ from
|
||||
host-generic-pci.txt:
|
||||
|
||||
- compatible : Must be "hisilicon,pcie-almost-ecam"
|
||||
|
||||
- reg : Two entries: First the ECAM configuration space for any
|
||||
other bus underneath the root bus. Second, the base
|
||||
and size of the HiSilicon host bridge registers include
|
||||
the RC's own config space.
|
||||
|
||||
Example:
|
||||
pcie0: pcie@a0090000 {
|
||||
compatible = "hisilicon,pcie-almost-ecam";
|
||||
reg = <0 0xb0000000 0 0x2000000>, /* ECAM configuration space */

<0 0xa0090000 0 0x10000>; /* host bridge registers */
