Subject: [PATCH v5 1/2] dt-bindings: PCI: dw: rockchip: Add rk3576 support
rk3576 is using dwc controller, with msi interrupt directly to gic instead
of to gic its, so
- no its support is required and the 'msi-map' is not need anymore,
- a new 'msi' interrupt is needed.
Signed-off-by: Kever Yang <kever.yang@...k-chips.com>
---
Changes in v5:
- Add constraints per device for interrupt-names due to the interrupt is
different from rk3588.
Changes in v4:
- Fix wrong indentation in dt_binding_check report by Rob
Changes in v3:
- Fix dtb check broken on rk3588
- Update commit message
Changes in v2:
- remove required 'msi-map'
- add interrupt name 'msi'
