Subject: [PATCH v2 0/2] dt-bindings: Convert Cadence PCIe RC/EP to DT Schema
Date: Mon, 17 Feb 2020 16:45:17 +0530	[thread overview]
Message-ID: <20200217111519.29163-1-kishon@ti.com> (raw)

Cadence PCIe IP is used by multiple SoC vendors (e.g. TI). Cadence
themselves have a validation platform for validating the PCIe IP which
is already in the upstream kernel. Right now the binding only exists for
Cadence platform and this will result in adding redundant binding schema
for any platform using Cadence PCIe core.

This series:
1) Create cdns-pcie.yaml which includes properties that are applicable
   to both host mode and endpoint mode of Cadence PCIe core.
2) Create cdns-pcie-host.yaml to include properties that are specific to
   host mode of Cadence PCIe core. cdns-pcie-host.yaml will include
   cdns-pcie.yaml.
3) Create cdns-pcie-ep.yaml to include properties that are specific to
   endpoint mode of Cadence PCIe core. cdns-pcie-ep.yaml will include
   cdns-pcie.yaml.
4) Remove cdns,cdns-pcie-ep.txt and cdns,cdns-pcie-host.txt which had
   the binding for Cadence "platform" and add cdns,cdns-pcie-host.yaml
   and cdns,cdns-pcie-ep.yaml schema for Cadence Platform. The schema
   for Cadence platform then includes schema for Cadence PCIe core.

Changes from v1:
*) Fix maximum values of num-lanes and cdns,no-bar-match-nbits
*) Fix example DT node for PCIe Endpoint.

Some of this was initially part of [1], but to accelerate it getting
into upstream, sending this as a separate series.
