From mboxrd@z Thu Jan 1 00:00:00 1970 From: Icenowy Zheng Subject: [PATCH] dt-bindings: add device tree binding for Allwinner XR819 SDIO Wi-Fi Date: Tue, 18 Jul 2017 15:29:40 +0800 Message-ID: <20170718072940.17872-1-icenowy@aosc.io> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Kalle Valo , Rob Herring , Maxime Ripard Cc: linux-wireless@vger.kernel.org, netdev@vger.kernel.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org, linux-sunxi@googlegroups.com, Icenowy Zheng List-Id: devicetree@vger.kernel.org Allwinner XR819 is a SDIO Wi-Fi chip, which has the functionality to use an out-of-band interrupt pin instead of SDIO in-band interrupt. Add the device tree binding of this chip, in order to make it possible to add this interrupt pin to device trees.
