[PATCH v2] dt-bindings: PCI: ti,am65: Fix remaining binding warnings

From: Jan Kiszka
Date: Thu Feb 15 2024 - 07:59:22 EST


From: Jan Kiszka <jan.kiszka@xxxxxxxxxxx>

This adds the missing num-viewport, phys and phy-name properties to the
schema. Based on driver code, num-viewport is required for the root
complex, phys are optional. Their number corresponds to the number of
lanes. The AM65x supports up to 2 lanes.

Signed-off-by: Jan Kiszka <jan.kiszka@xxxxxxxxxxx>

Changes in v2:
- limit phy-names to pcie-phy[0-1]
- fix schema-checking of example
