* smart_battery: Remove smart charger unreachable codeVijay Hiremath2016-10-111-6/+0

* cleanup: fix all the header guardsBill Richardson2015-06-181-3/+3
| | | | | | | | | | | | | | | This unifies all the EC header files to use __CROS_EC_FILENAME_H as the include guard. Well, except for test/ util/ and extra/ which use __TEST_ __UTIL_ and __EXTRA_ prefixes respectively.

* samus: Kick battery out of disconnect state when AC is attachedShawn Nematbakhsh2014-07-231-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Samus battery can be placed into a disconnect state by asserting a disconnect input signal. In this state, the battery will not function until a charging current is applied. This patch adds detection of the disconnect state. If a battery in disconnect state is found, a current is force-applied to the battery to kick it out of disconnect. BRANCH=None TEST=Manual on Samus. 1. Put battery into disconnect state 2. Pull AC, then reattach AC 3. Verify "found battery in disconnect state" is seen on the EC console. 4. Pull AC and verify that EC console is still accessable Also verify that battery gets out of reset state: 1. Pull AC 2. Issue "i2cxfer w16 0 0x16 0x0 0x12" command on EC console 3. Re-attach AC 4. Pull AC and verify that EC console is still accessable BUG=chrome-os-partner:29465 Signed-off-by: Shawn Nematbakhsh <shawnn@chromium.org> Change-Id: Ib4268887fb483094ac4e641749200268160d3014 Reviewed-on: https://chromium-review.googlesource.com/209013 Reviewed-by: Alec Berg <alecaberg@chromium.org> Commit-Queue: Alec Berg <alecaberg@chromium.org> Tested-by: Alec Berg <alecaberg@chromium.org>
* Show smart battery status with 'battery' commandBill Richardson2013-11-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | The smart battery status register holds some useful info. This displays it along with all the other stuff. This decodes the alarm and status bits, but not the error code, since that field is only valid immediately after a failed i2c transaction (that's how the battery indicates error). Since we do all sorts of automatic battery probing in other threads, that value will never be reliable when we run the "battery" console command. BUG=none BRANCH=none TEST=manual Run "battery". You should see a new line amongst the output: Status: 0x00c0 DCHG INIT Change-Id: I5e684198af2cf7767f89786c91a7d946ad95d4c2 Signed-off-by: Bill Richardson <wfrichar@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/175659
* cleanup: Battery header files and filenamesRandall Spangler2013-10-071-0/+143
battery.h is the high-level interface. battery_smart.h is the low-level interface. Most things don't need the low-level interface, but were including smart_battery.h solely to get at battery.h. Fixed this. Also merged battery_pack.h into battery.h, since it was odd to split that data across multiple header files. Tidied the function comments in battery.h as well. No functional changes, just renaming files and adding comments.
