Subject: [PATCH V6 12/15] arm64: tegra: Enable PCIe slots in P2972-0000 board
Date: Mon, 13 May 2019 10:36:23 +0530
Message-ID: <20190513050626.14991-13-vidyas@nvidia.com> (raw)
In-Reply-To: <20190513050626.14991-1-vidyas@nvidia.com>

Enable PCIe controller nodes to enable respective PCIe slots on
P2972-0000 board. Following is the ownership of slots by different
PCIe controllers.
Controller-0 : M.2 Key-M slot
Controller-1 : On-board Marvell eSATA controller
Controller-3 : M.2 Key-E slot

Signed-off-by: Vidya Sagar <vidyas@nvidia.com>
---
Changes since [v5]:
* Arranged PCIe nodes in the order of their addresses

Changes since [v4]:
* None

Changes since [v3]:
* None

Changes since [v2]:
* Changed P2U label names to reflect new format that includes 'hsio'/'nvhs'
  strings to reflect UPHY brick they belong to

Changes since [v1]:
* Dropped 'pcie-' from phy-names property strings
