olpc_battery: Fix endian neutral breakage for s16 values

2010-09-28T11:14:31+00:00

When the driver was updated to be endian neutral (8e9c7716c)
the signed part of the s16 values was lost.  This is because be16_to_cpu()
returns an unsigned value.  This patch casts the values back to a s16
number prior to the the implicit cast up to an int.

olpc_battery: Fix build failure caused by sysfs changes

drivers/power/olpc_battery.c:387: error: unknown field 'owner' specified in initializer
drivers/power/olpc_battery.c:387: warning: excess elements in struct initializer
drivers/power/olpc_battery.c:387: warning: (near initialization for 'olpc_bat_eeprom.attr')

The .owner field has been dropped from the attr struct.

sysfs: add struct file* to bin_attr callbacks

2010-05-21T16:37:31+00:00

This allows bin_attr->read,write,mmap callbacks to check file specific data
(such as inode owner) as part of any privilege validation.

power_supply: Add a charge_type property, and use it for olpc driver

2009-07-02T14:14:37+00:00

This adds a new sysfs file called 'charge_type' which displays the
type of charging (unknown, n/a, trickle charge, or fast charging).

This allows things like battery diagnostics to determine what the
battery/EC is doing without resorting to changing the 'status' sysfs
output.

olpc_battery: Add an 'error' sysfs device that displays raw errors

2009-06-30T22:48:37+00:00

Grab the error code from EC_BAT_ERRCODE and let the user see it (rather
than attempting to decode it as we do with PROP_HEALTH) with a separate
error sysfs file.

Revert "power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL"

2009-06-30T22:44:03+00:00

This reverts commit 8efe444038a205e79b38b7ad03878824901849a8 and
4cbc76eadf56399cd11fb736b33c53aec9caab8c.

Richard@laptop.org was apparently using CAPACITY_LEVEL for debugging
battery/EC problems, and was upset that it was removed.  This readds it.

olpc_battery: Ensure that the TRICKLE bit is checked

2009-06-30T22:36:58+00:00

There are times when the battery is present but trickle charging,
and the EC sets only the TRICKLE bit. So we must check for the bit
when we're checking the charging/present status.

olpc_battery: Fix up eeprom read function

2009-06-30T22:36:38+00:00

The eeprom read function was placing values into the wrong place in
'buf'; we were starting from buf[off], rather than buf[0].

Also, the for loop that we were using was much uglier than it needed to
be.  This cleans it up a bit.

power_supply: fix up CHARGE_COUNTER output to be more precise

2008-05-18T21:44:36+00:00

As Richard Smith pointed out, ACR * 6250 / 15 provides for less
precision loss than ACR * 4167 / 10, _and_ it doesn't overflow.  Switch
to using that equation for CHARGE_COUNTER.
