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/i2c/other/Makefile | 17 - ANDROID_3.4.5/sound/i2c/other/ak4113.c | 639 ----------------- ANDROID_3.4.5/sound/i2c/other/ak4114.c | 626 ----------------- ANDROID_3.4.5/sound/i2c/other/ak4117.c | 552 --------------- ANDROID_3.4.5/sound/i2c/other/ak4xxx-adda.c | 945 -------------------------- ANDROID_3.4.5/sound/i2c/other/pt2258.c | 227 ------- ANDROID_3.4.5/sound/i2c/other/tea575x-tuner.c | 427 ------------ 7 files changed, 3433 deletions(-) delete mode 100644 ANDROID_3.4.5/sound/i2c/other/Makefile delete mode 100644 ANDROID_3.4.5/sound/i2c/other/ak4113.c delete mode 100644 ANDROID_3.4.5/sound/i2c/other/ak4114.c delete mode 100644 ANDROID_3.4.5/sound/i2c/other/ak4117.c delete mode 100644 ANDROID_3.4.5/sound/i2c/other/ak4xxx-adda.c delete mode 100644 ANDROID_3.4.5/sound/i2c/other/pt2258.c delete mode 100644 ANDROID_3.4.5/sound/i2c/other/tea575x-tuner.c (limited to 'ANDROID_3.4.5/sound/i2c/other') diff --git a/ANDROID_3.4.5/sound/i2c/other/Makefile b/ANDROID_3.4.5/sound/i2c/other/Makefile deleted file mode 100644 index c95d8f1a..00000000 --- a/ANDROID_3.4.5/sound/i2c/other/Makefile +++ /dev/null @@ -1,17 +0,0 @@ -# -# Makefile for ALSA -# Copyright (c) 2003 by Jaroslav Kysela -# - -snd-ak4114-objs := ak4114.o -snd-ak4117-objs := ak4117.o -snd-ak4113-objs := ak4113.o -snd-ak4xxx-adda-objs := ak4xxx-adda.o -snd-pt2258-objs := pt2258.o -snd-tea575x-tuner-objs := tea575x-tuner.o - -# Module Dependency -obj-$(CONFIG_SND_PDAUDIOCF) += snd-ak4117.o -obj-$(CONFIG_SND_ICE1712) += snd-ak4xxx-adda.o -obj-$(CONFIG_SND_ICE1724) += snd-ak4114.o snd-ak4113.o snd-ak4xxx-adda.o snd-pt2258.o -obj-$(CONFIG_SND_TEA575X) += snd-tea575x-tuner.o diff --git a/ANDROID_3.4.5/sound/i2c/other/ak4113.c b/ANDROID_3.4.5/sound/i2c/other/ak4113.c deleted file mode 100644 index dde5c9c9..00000000 --- a/ANDROID_3.4.5/sound/i2c/other/ak4113.c +++ /dev/null @@ -1,639 +0,0 @@ -/* - * Routines for control of the AK4113 via I2C/4-wire serial interface - * IEC958 (S/PDIF) receiver by Asahi Kasei - * Copyright (c) by Jaroslav Kysela - * Copyright (c) by Pavel Hofman - * - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
