Hi Dmitry,
ONKEY Driver for Dialog Semiconductor DA9052 PMICs.
Changes made since last submission:
. made changes to error handling in probe function
. changed variable names to reflect their use

The delay here is in jiffies so the duration of the delay is
will be different for different values of HZ. I think you want
msecs_to_jiffies(10) here.

No need to cast void * pointers.

Why is this threaded IRQ if your interrupt handler siumply schedules
delayed work to actually query the device? Is iut because it is a nested
interrupt?

We have a main line interrupt which gets triggered when DA9052 devices generates events/interrupts.
The oneshot handler for the main interrupt finds out the active interrupts and wake ups the relevant
interrupt threads that are associated with individual DA9052 events. For this reason, onkey device gets register for the threaded interrupt.
