git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB: transceiver changes for 3.4 Here we have a big rework done by Heikki Krogerus (thanks) which splits OTG functionality away from transceivers. We have known for quite a long time that struct otg_transceiver was a bad name for the structure, considering transceiver is far from being OTG-specific (see 4e67185).

When reading flags, bq27x00_read() argument is inverted and causes reads 2 of bytes for bq27200 and 1 byte for bq27500, while their register sizes are 1 and 2 bytes respectively. This causes bq27500 upper flag bits always to be returned as 0, causing full charge state to never be reported correctly, so fix it.

This reverts commit 270968c0984aeed096da3cfffb0e131f4c416166. Grazvydas Ignotas wrote: After 270968c0984ae "bq27x00_battery: Fix reporting status value for bq27500 battery" status doesn't seem to be reported correctly when the battery is close to fully charged state. It reports "Not charging" while in fact there is >130mA current flowing to the battery according to current_now. This status report seems to be based on CHG bit in status register, but looking at the datasheet the description says "(Fast) charging allowed", which I guess means that the chip recommends charging and not that charging is actually going on? If you check the bit while battery is discharging and it's not full, the bit is also set.

2012-01-06s3c_adc_battery: Average over more than one adc sampleHeiko Stübner1-3/+22
Some sources for adc battery information provide only inaccurate results where the read value differs from the real value with positive and negative offsets. For such sources it can be more accurate to collect two or more value sample and use the average of all collected values. This patch adds pdata options volt_samples, current_samples and backup_volt_samples to specifiy the number of samples to collect, reads the specified number of samples and calculates the average of those. For unset sample-number-values a default of 1 is assumed. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>

2012-01-06power_supply: Assume mains power by defaultJean Delvare1-1/+11
If no power class device is found in power_supply_is_system_supplied(), the function currently returns 0, which basically means that the system is supposed to be running on battery. In practice, mobile devices tend to always implement at least one power class device and more often two (battery and AC adapter). Systems with no registered power class devices are more likely to be desktop systems, where the system is always powered by mains. So, change the default return value of power_supply_is_system_supplied() from 0 (running on battery) to 1 (running on mains.)

There are presently three possible values: Unknown - unknown power topology System - the power supply powers the whole system Device - it powers a specific device, or tree of devices A power supply which doesn't have a "scope" attribute should be assumed to have "System" scope. In general, usermode should assume that loss of all System-scoped power supplies will power off the whole system, but any single one is sufficient to power the system.
