Subject: [PATCH V2 11/16] dt-bindings: PHY: P2U: Add Tegra 194 P2U block
Date: Fri, 5 Apr 2019 01:24:38 +0530 [thread overview]
Message-ID: <1554407683-31580-12-git-send-email-vidyas@nvidia.com> (raw)
In-Reply-To: <1554407683-31580-1-git-send-email-vidyas@nvidia.com>
Add support for Tegra194 P2U (PIPE to UPHY) module block which is a glue
module instantiated one for each PCIe lane between Synopsys Designware core
based PCIe IP and Universal PHY block.

+NVIDIA Tegra194 P2U binding
+
+Tegra194 has two PHY bricks namely HSIO (High Speed IO) and NVHS (NVIDIA High
+Speed) each interfacing with 12 and 8 P2U instances respectively.
+A P2U instance is a glue logic between Synopsys DesignWare Core PCIe IP's PIPE
+interface and PHY of HSIO/NVHS bricks. Each P2U instance represents one PCIe
+lane.
+
+Required properties:
+- compatible: For Tegra19x, must contain "nvidia,tegra194-p2u".
+- reg: Should be the physical address space and length of respective each P2U
+ instance.
+- reg-names: Must include the entry "ctl".
+
+Required properties for PHY port node:
+- #phy-cells: Defined by generic PHY bindings. Must be 0.
+
+Refer to phy/phy-bindings.txt for the generic PHY binding properties.
+
+Example:
+
+p2u_0: p2u@03e10000 {
+ compatible = "nvidia,tegra194-p2u";
+ reg = <0x03e10000 0x10000>;
+ reg-names = "ctl";
+
+ #phy-cells = <0>;
+};
