1 HiSilicon STB PCIe host bridge DT description
3 The HiSilicon STB PCIe host controller is based on the DesignWare PCIe core.
4 It shares common functions with the DesignWare PCIe core driver and inherits
5 common properties defined in
6 Documentation/devicetree/bindings/pci/designware-pcie.txt.
8 Additional properties are described here:
11 - compatible: Should be one of the following strings:
12 "hisilicon,hi3798cv200-pcie"
13 - reg: Should contain sysctl, rc_dbi, config registers location and length.
14 - reg-names: Must include the following entries:
15 "control": control registers of PCIe controller;
16 "rc-dbi": configuration space of PCIe controller;
17 "config": configuration transaction space of PCIe controller.
18 - bus-range: PCI bus numbers covered.
19 - interrupts: MSI interrupt.
20 - interrupt-names: Must include "msi" entries.
21 - clocks: List of phandle and clock specifier pairs as listed in clock-names
23 - clock-name: Must include the following entries:
24 "aux": auxiliary gate clock;
25 "pipe": pipe gate clock;
26 "sys": sys gate clock;
27 "bus": bus gate clock.
28 - resets: List of phandle and reset specifier pairs as listed in reset-names
30 - reset-names: Must include the following entries:
36 - reset-gpios: The gpio to generate PCIe PERST# assert and deassert signal.
37 - phys: List of phandle and phy mode specifier, should be 0.
38 - phy-names: Must be "phy".
