The other 2 are fine from me. This driver does need some work to move it out of staging. I am not sure what would be a big blocker for it, other than maybe it needs a device-tree binding doc (in YAML format). Maybe Jonathan remembers. Some other low-hanging-fruit ideas would be: 1) remove the code for platform_data ; that one seems forgotten from some other time; the interrupts should be coming from device-tree, from the i2c bindings 2) you could do a AD7150_EVENT_SPEC() macro (similar to AD7150_TIMEOUT() macro) and use it in the ad7150_events[] list; that would reduce a few lines 3) similar to 2), you could do a AD7150_CHANNEL(x) macro ; 4) in ad7150_event_handler() the checks could be wrapped into a macro, or maybe some function ; i am referring to "(int_status & AD7150_STATUS_OUT1) && (chip->old_state & AD7150_STATUS_OUT1)" checks ; those seem to be repeated 5) add of_match_table to the driver I (now) suspect that the reason this driver is still in staging is this comment: /* Timeouts not currently handled by core */ I wonder if things changed since then ? If not, it would be interesting to implement it in core.
