From 3a4be6a092c89ad7a94b147c3529d6626e5a59ff Mon Sep 17 00:00:00 2001 From: Jes Sorensen Date: Mon, 29 Feb 2016 17:04:58 -0500 Subject: [PATCH] rtl8xxxu: Init H2C command register for 8723bu In addition make register read/write flow match closer to vendor driver flow. This is mainly to be able to compare the register write log with the vendor driver, and can be optimized later once 8723bu support is working.
