mfd: use a dedicated workqueue for pcf50633 irq processing 2009-09-17T07:46:53+00:00 Paul Fertser fercerpav@gmail.com 2009-07-27T20:41:15+00:00 ed52e62ebec9e703eb0b69704feaf1b6e847d882 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.

But 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 80%. This work_struct function restarts charging at regular intervals to make sure the battery doesn't discharge too much.
