Subject: [PATCH 4/5] dt-bindings: Add Qualcomm USB SuperSpeed PHY bindings
Date: Wed, 11 Mar 2020 19:13:57 +0000	[thread overview]
Message-ID: <20200311191358.8102-5-bryan.odonoghue@linaro.org> (raw)
In-Reply-To: <20200311191358.8102-1-bryan.odonoghue@linaro.org>

From: Jorge Ramirez-Ortiz <jorge.ramirez-ortiz@linaro.org>

Binding description for Qualcomm's Synopsys 1.0.0 SuperSpeed PHY. This PHY
appears in a number of SoCs on various flavors of 20nm and 28nm nodes.

This commit adds information related to the 28nm node only.

Based on Sriharsha Allenki's <sallenki@codeaurora.org> original
definitions.
