Hi,
The qcom,pcie.yaml containing all devices results in huge allOf: section
with a lot of if:then: clauses making review and changes quite
difficult.
Split common parts into common schema and then move few devices to
dedicated files, so that each file will be easier to review.
I did not split/move all devices yet, so if this gets accepted I plan to
send more patches.
Best regards,
Krzysztof

The qcom,pcie.yaml binding file containing all possible Qualcomm SoC
PCIe root complexes gets quite complicated with numerous if:then:
conditions customizing clocks, interrupts, regs and resets. Adding and
reviewing new devices is difficult, so simplify it by having shared
common binding and file with only one group of compatible devices:
1. Copy all common qcom,pcie.yaml properties (so everything except
supplies) to a new shared qcom,pcie-common.yaml schema.
2. Move SM8550 PCIe compatible devices to dedicated binding file.
This creates equivalent SM8550 schema file, except missing required
compatible which is actually redundant.

Move SM8450 PCIe devices from qcom,pcie.yaml binding to a dedicated file
to make reviewing easier.
This creates equivalent schema file, except missing required compatible
which is actually redundant.

Move SM8250 PCIe devices from qcom,pcie.yaml binding to a dedicated file
to make reviewing easier.
This creates equivalent schema file, except missing required compatible
which is actually redundant.

Move SM8350 PCIe devices from qcom,pcie.yaml binding to a dedicated file
to make reviewing easier.
This creates equivalent schema file, except missing required compatible
which is actually redundant.
