From: Niklas Cassel <niklas.cassel@xxxxxxx>
Even though rockchip-dw-pcie.yaml inherits snps,dw-pcie.yaml
using:
allOf:
- $ref: /schemas/pci/snps,dw-pcie.yaml#
and snps,dw-pcie.yaml does have the atu reg defined, in order to be
able to use this reg, while still making sure 'make CHECK_DTBS=y'
pass, we need to add this reg to rockchip-dw-pcie.yaml.
All compatible strings (rockchip,rk3568-pcie and rockchip,rk3588-pcie)
should have this reg.
The regs in the example are updated to actually match pcie3x2 on rk3568.
