2009-08-02pcf50633: get rid of charging restart software auto-triggeringPaul Fertser
After reaching Battery Full condition MBC state machine switches back into charging mode when the battery voltage falls below 96% of a battery float voltage. The voltage drop in Li-Ion batteries is marginal (1-2%) till about 80% of its capacity - which means, after a BATFULL, charging won't be restarted until 75-80%. That is a desired behaviour recommended by battery manufacturers, don't mess with it. Signed-off-by: Paul Fertser <fercerpav@gmail.com>

2009-08-02pcf50633: revise locking for ADCPaul Fertser
Current implementation is prone to races, this patch attempts to remove all but one (in pcf50633_adc_sync_read). The idea is that we need to guard the queue access only on inserting and removing items. If we insert and there're no more items in the queue it means that the last irq already happened and we need to trigger ADC manually. If not, then the next conversion will be triggered by the irq handler upon completion of the previous. Signed-off-by: Paul Fertser <fercerpav@gmail.com>
2009-08-02pcf50633: use a dedicated workqueue for irq processingPaul Fertser
Using the default kernel "events" workqueue causes problems with synchronous adc readings if initiated from some task on the same workqueue. I had a deadlock trying to use pcf50633_adc_sync_read from a power_supply class driver because the reading was initiated from the workqueue and it waited for the irq processing to complete (to get the result) and that was put on the same workqueue.

2009-08-02gta01_battery: add charge_{now,full} propertiesPaul Fertser
Some userspace (notably Enlightment's batget) ignores "capacity" completely if there're no other properties. Expose a fake value (850mAh, typical for BL-5C) to make them happy. Signed-off-by: Paul Fertser <fercerpav@gmail.com>
2009-08-02gta01_battery: generalise the driver, add capacity estimationPaul Fertser
Check if machine-specific hooks exist before calling, this allows to use this driver with gta02 or any other device that is able to provide battery voltage readings. Report an estimate of capacity percentage left, based on discharge curves. Strictly speaking, this is a violation of power_supply class specs but since this is the only driver for dumb batteries and userspace lacks any library to do the estimation itself, we have to stuff it here. Please keep in mind that this estimation is by no means accurate, usually cell phones have only 5 bars to represent charge status. Credit goes to Joerg Reisenweber and SpeedEvil for helping with gathering and analysing the data. Signed-off-by: Paul Fertser <fercerpav@gmail.com>

2009-07-27bq27000: Return -ENODEV in bq27000_battery_get_property if the battery is notLars-Peter Clausen
If the battery is not present hdq_read will always return an error. If the drivers knows that the battery is not present the correct thing to do is to return -ENODEV instead of passing the error on. Do this for all properties except POWER_SUPPLY_PROP_PRESENT. The power supply sysfs expects us to do so, else it won't generate a proper uevent file.

2009-06-13gta02: move debugging messages to the appropriate levelsPaul Fertser
Clean up debugging messages so that we don't see any output with loglevel=4 (default for Qi). This avoids slowing down suspend/resume by slow fb output. Checkpatch barks on this patch but i guess most of that debugging would have to be changed prior to upstream submission anyway. Signed-off-by: Paul Fertser <fercerpav@gmail.com>

2009-06-09GTA0[12]: make headset button report PLAY pressed on pressPaul Fertser
As discussed on the ML, currently headset button reports "KEY_PAUSE released" on press and "pressed" on release. For "pause" semantics it makes sense but if someone thinks of that as of just another button, it'd be good to have "pressed/released" events consistent with button press/release. Luca Capello <luca@pca.it> suggested to change the button event to KEY_PLAY and to invert the state to make it more consistent. This trivial patch inverts button events for GTA03 KEY_PLUS and KEY_MINUS, i'm not sure how undesirable that is. I can prepare an alternative that preserves current behaviour on GTA03 per request.

2009-06-04GTA02: bq27000 report current chargePaul Fertser
Using HAL for E's battery gadget highlighted an oddity: the kernel exposed last full charge property but didn't expose current charge property. This resulted in the wrong computation of current battery capacity by E's gadget (and probably other programs as well). This patch exposes a corresponding bq27000 register to make E battery gadget happy (it is still not showing correct values because of bugs in HAL resulting in 3 batteries (apm emulation and usb supply being bogus here) instead of one).

2009-05-25gta01: fix jbt6k74 spi registrationPaul Fertser
Without this jbt6k74 is not seen by the system and consequently display doesn't work with Qi. Rebasing to .28 introduced a regression (probably in a6af63e826b79ae1ba2d8cbfa66805cc2dfe367c) resulting in jbt6k74 no longer manageable by the kernel. This was unnoticed before because u-boot does its own LCM initialization. With Qi it resulted in a white screen. This patch is fixing it by making spi host bus number (unspecified, defaults to 0) and spi device (jbt6k74) bus number match. Signed-off-by: Paul Fertser <fercerpav@gmail.com>

2009-05-15 This patch adds the option to poll vbus status to the s3c24xx udc driver.Mike Westerhof
Machines that do not route the USB vbus signal to a GPIO can use this mechanism as an alternate way for the udc driver to detect the usb connect/disconnect state, which is useful (for example) to enable the link up/down state to be determined for the g_ether gadget.

2009-05-15usb gadget: fix ethernet link reports to ethtoolJonathan McDowell
The g_ether USB gadget driver currently decides whether or not there's a link to report back for eth_get_link based on if the USB link speed is set. The USB gadget speed is however often set even before the device is enumerated. It seems more sensible to only report a "link" if we're actually connected to a host that wants to talk to us. The patch below does this for me - tested with the PXA27x UDC driver.
