From 05f12e08772d1ca03101b176e329bfd313daf673 Mon Sep 17 00:00:00 2001 From: Thomas Martitz Date: Sat, 31 Dec 2011 13:34:56 +0000 Subject: ypr0: Enable battery voltage read-out, charging monitoring and charger detection. Voltage can be read using as3543 adc (i.e. ascodec api, on this target implemented via ioctl()). TODO: Look into possibly controlling charging more by re-using powermgmt-ascodec.c. However, charging seems to be controlled by the kernel, so may not be needed. Charger state can be read using /dev/minivet. It allows to differentiate between wall charger and usb charging, but that's not implemented (is it even worthwhile?) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31470 a1c6a512-1295-4272-9138-f99709370657 --- firmware/SOURCES | 2 +- firmware/export/config/samsungypr0.h | 18 ++-- firmware/export/power.h | 3 + firmware/export/powermgmt.h | 2 +- firmware/export/storage.h | 2 +- firmware/powermgmt.c | 4 +- firmware/target/hosted/ypr0/powermgmt-ypr0.c | 115 +++++++---------------- firmware/target/hosted/ypr0/sc900776.h | 134 +++++++++++++++++++++++++++ firmware/target/hosted/ypr0/system-ypr0.c | 11 +-- 9 files changed, 189 insertions(+), 102 deletions(-) create mode 100644 firmware/target/hosted/ypr0/sc900776.h (limited to 'firmware') diff --git a/firmware/SOURCES b/firmware/SOURCES index e80a7492b1..46ef51beea 100644 --- a/firmware/SOURCES +++ b/firmware/SOURCES @@ -13,8 +13,8 @@ powermgmt.c target/hosted/cpuinfo-linux.c #endif -target/hosted/powermgmt.c #ifndef SAMSUNG_YPR0 /* uses as3514 rtc */ +target/hosted/powermgmt.c target/hosted/rtc.c #endif #endif diff --git a/firmware/export/config/samsungypr0.h b/firmware/export/config/samsungypr0.h index 25e1906a80..8d133c4e24 100644 --- a/firmware/export/config/samsungypr0.h +++ b/firmware/export/config/samsungypr0.h @@ -21,7 +21,7 @@ #define USB_NONE /* Hardware controlled charging with monitoring */ -//#define CONFIG_CHARGING CHARGING_MONITOR +#define CONFIG_CHARGING CHARGING_MONITOR /* There is only USB charging */ //#define HAVE_USB_POWER @@ -127,16 +127,16 @@ /* Define current usage levels. */ /* TODO: to be filled with correct values after implementing power management */ -#define CURRENT_NORMAL 88 /* 18 hours from a 1600 mAh battery */ -#define CURRENT_BACKLIGHT 30 /* TBD */ -#define CURRENT_RECORD 0 /* no recording yet */ +//#define CURRENT_NORMAL 88 /* 18 hours from a 1600 mAh battery */ +//#define CURRENT_BACKLIGHT 30 /* TBD */ +//#define CURRENT_RECORD 0 /* no recording yet */ /* TODO: We need to do battery handling */ -//#define BATTERY_CAPACITY_DEFAULT 600 /* default battery capacity */ -//#define BATTERY_CAPACITY_MIN 600 /* min. capacity selectable */ -//#define BATTERY_CAPACITY_MAX 700 /* max. capacity selectable */ -//#define BATTERY_CAPACITY_INC 50 /* capacity increment */ -//#define BATTERY_TYPES_COUNT 1 /* only one type */ +#define BATTERY_CAPACITY_DEFAULT 600 /* default battery capacity */ +#define BATTERY_CAPACITY_MIN 600 /* min. capacity selectable */ +#define BATTERY_CAPACITY_MAX 600 /* max. capacity selectable */ +#define BATTERY_CAPACITY_INC 0 /* capacity increment */ +#define BATTERY_TYPES_COUNT 1 /* only one type */ /* TODO: We possibly can only watch linux charging */ //#define CONFIG_CHARGING CHARGING_TARGET diff --git a/firmware/export/power.h b/firmware/export/power.h index d46b9ba924..4937705910 100644 --- a/firmware/export/power.h +++ b/firmware/export/power.h @@ -23,6 +23,7 @@ #include "config.h" +#if (CONFIG_PLATFORM & PLATFORM_NATIVE) || defined(SAMSUNG_YPR0) #if CONFIG_CHARGING enum power_input_flags { /* No external power source?
