From 5e93f35209578fcabfa855e427354195e54b491f Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Fri, 28 Mar 2014 21:37:38 -0500 Subject: [PATCH] staging: r8723au: Add source files for new driver - part 1 The Realtek USB device RTL8723AU is found in Lenovo Yoga 13 tablets. A driver for it has been available in a GitHub repo for several months. This commit contains the first part of the source files. The source is arbitrarily split to avoid E-mail files that are too large. Jes Sorensen at RedHat has made many improvements to the vendor code, and he has been doing the testing. I do not have access to this device.
