From 60592165ca998875e4bc46c4396c5a123a7e9dbb Mon Sep 17 00:00:00 2001 From: Lorenzo Miori Date: Sat, 23 Feb 2013 16:59:49 +0100 Subject: Samsung YP-R0 hosted target code refactoring As per title this patch aims at splitting common target code and specific target code in a better way to support future ports within the same environment (e.g. Samsung YP-R1 where the Linux and the SoC are the same, with differences in hardware devices handling) Change-Id: I67b4918c46403b184d3d8f42ab5aae7d01037fd0 Reviewed-on: http://gerrit.rockbox.org/409 Reviewed-by: Thomas Martitz Tested-by: Thomas Martitz --- .../target/hosted/samsungypr/ypr0/gpio-target.h | 62 ++++++++++++++++++++++ 1 file changed, 62 insertions(+) create mode 100644 firmware/target/hosted/samsungypr/ypr0/gpio-target.h (limited to 'firmware/target/hosted/samsungypr/ypr0/gpio-target.h') diff --git a/firmware/target/hosted/samsungypr/ypr0/gpio-target.h b/firmware/target/hosted/samsungypr/ypr0/gpio-target.h new file mode 100644 index 0000000000..3c2033baff --- /dev/null +++ b/firmware/target/hosted/samsungypr/ypr0/gpio-target.h @@ -0,0 +1,62 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * + * Module wrapper for GPIO, using /dev/r0GPIO (r0Gpio.ko) of Samsung YP-R0 + * + * Copyright (c) 2011 Lorenzo Miori + * + * 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 software is distributed on an "AS IS" basis, WITHOUT WARRANTY OF ANY + * KIND, either express or implied. + * + ****************************************************************************/ + +#ifndef GPIO_YPR0_H +#define GPIO_YPR0_H + +#include "r0GPIOIoctl.h" + +/* Some meaningful pins used in the R0 */ + +#define GPIO_HEADPHONE_SENSE GPIO1_5 +#define GPIO_EXT_PWR_SENSE GPIO1_26 +#define GPIO_SD_SENSE GPIO2_27 +#define GPIO_AS3543_INTERUPT GPIO1_25 +#define GPIO_PCB_VER_DETECT GPIO_10 +/* I2C bus for AS3543 codec */ +#define GPIO_I2C_CLK0 GPIO_1_0 +#define GPIO_I2C_DAT0 GPIO_1_1 +/* I2C bus for the SI4079 FM radio chip */ +#define GPIO_I2C_CLK1 GPIO_2_12 +#define GPIO_I2C_DAT1 GPIO_2_13 +#define GPIO_FM_SEARCH GPIO1_4 +#define GPIO_FM_BUS_EN GPIO2_19 + +/* Keypad */ + +#define GPIO_BACK_KEY GPIO2_29 +#define GPIO_USER_KEY GPIO2_30 +#define GPIO_MENU_KEY GPIO2_31 +#define GPIO_POWER_KEY GPIO2_16 +#define GPIO_CENTRAL_KEY GPIO3_5 +#define GPIO_UP_KEY GPIO3_9 +#define GPIO_DOWN_KEY GPIO3_8 +#define GPIO_LEFT_KEY GPIO2_28 +#define GPIO_RIGHT_KEY GPIO3_7 + + +void gpio_init(void); +void gpio_close(void); +int gpio_control_struct(int request, R0GPIOInfo pin); +int gpio_control(int request, int num, int mode, int val); + +#endif -- cgit v1.2.3
