From 871480933a1c28f8a9fed4c4d34d06c439a7a422 Mon Sep 17 00:00:00 2001 From: Srikant Patnaik Date: Sun, 11 Jan 2015 12:28:04 +0530 Subject: Moved, renamed, and deleted files The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure. --- ANDROID_3.4.5/sound/soc/codecs/ad1836.c | 398 -------------------------------- 1 file changed, 398 deletions(-) delete mode 100644 ANDROID_3.4.5/sound/soc/codecs/ad1836.c (limited to 'ANDROID_3.4.5/sound/soc/codecs/ad1836.c') diff --git a/ANDROID_3.4.5/sound/soc/codecs/ad1836.c b/ANDROID_3.4.5/sound/soc/codecs/ad1836.c deleted file mode 100644 index 12e3b411..00000000 --- a/ANDROID_3.4.5/sound/soc/codecs/ad1836.c +++ /dev/null @@ -1,398 +0,0 @@ - /* - * Audio Codec driver supporting: - * AD1835A, AD1836, AD1837A, AD1838A, AD1839A - * - * Copyright 2009-2011 Analog Devices Inc. - * - * Licensed under the GPL-2 or later. - */ - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include "ad1836.h" - -enum ad1836_type { - AD1835, - AD1836, - AD1838, -};
