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/powermgmt-ypr0.c | 107 +++++++++++++++++++++ 1 file changed, 107 insertions(+) create mode 100644 firmware/target/hosted/samsungypr/ypr0/powermgmt-ypr0.c (limited to 'firmware/target/hosted/samsungypr/ypr0/powermgmt-ypr0.c') diff --git a/firmware/target/hosted/samsungypr/ypr0/powermgmt-ypr0.c b/firmware/target/hosted/samsungypr/ypr0/powermgmt-ypr0.c new file mode 100644 index 0000000000..6e04d25f58 --- /dev/null +++ b/firmware/target/hosted/samsungypr/ypr0/powermgmt-ypr0.c @@ -0,0 +1,107 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * + * 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. + * + ****************************************************************************/ +#include "config.h" +#include +#include "kernel.h" +#include "powermgmt.h" +#include "power.h" +#include "file.h" +#include "adc.h" +#include "sc900776.h" +#include "radio-ypr.h" + +const unsigned short battery_level_dangerous[BATTERY_TYPES_COUNT] = +{ + 3470 +}; + +/* the OF shuts down at this voltage */ +const unsigned short battery_level_shutoff[BATTERY_TYPES_COUNT] = +{ + 3450 +}; + +/* voltages (millivolt) of 0%, 10%, ... 100% when charging disabled */ +const unsigned short percent_to_volt_discharge[BATTERY_TYPES_COUNT][11] = +{ + { 3450, 3502, 3550, 3587, 3623, 3669, 3742, 3836, 3926, 4026, 4200 } +}; + +#if CONFIG_CHARGING +/* voltages (millivolt) of 0%, 10%, ... 100% when charging enabled */ +const unsigned short const percent_to_volt_charge[11] = +{ + 3450, 3670, 3721, 3751, 3782, 3821, 3876, 3941, 4034, 4125, 4200 +}; + +unsigned int power_input_status(void) +{ + unsigned status = POWER_INPUT_NONE; + int fd = open("/dev/minivet", O_RDONLY); + if (fd >= 0) + { + if (ioctl(fd, IOCTL_MINIVET_DET_VBUS, NULL) > 0) + status = POWER_INPUT_MAIN_CHARGER; + close(fd); + } + return status; +} + +#endif /* CONFIG_CHARGING */ + + +/* Returns battery voltage from ADC [millivolts], + * adc returns voltage in 5mV steps */ +int _battery_voltage(void) +{ + return adc_read(3) * 5; +} + +bool charging_state(void) +{ + const unsigned short charged_thres = 4170; + bool ret = (power_input_status() == POWER_INPUT_MAIN_CHARGER); + /* dont indicate for > ~95% */ + return ret && (_battery_voltage() <= charged_thres); +} + +#if CONFIG_TUNER +static bool tuner_on = false; + +bool tuner_power(bool status) +{ + if (status != tuner_on) + { + tuner_on = status; + status = !status; + if (tuner_on) { + radiodev_open(); + } + else { + radiodev_close(); + } + } + + return status; +} + +bool tuner_powered(void) +{ + return tuner_on; +} +#endif /* #if CONFIG_TUNER */ \ No newline at end of file -- cgit v1.2.3
