[PATCH v2 00/13] iio: pressure: mprls0025pa: driver code cleanup
Posted by Petre Rodan 3 weeks, 4 days ago
This series contains a collection of patches to the MPR sensor based
on feedback I received for other drivers.

major changes:
 - trigger flag fix (define edge direction only in the device tree)
 - fix SPI timing violation
 - fix scan_type struct
 - fix pressure calculation
    (does not affect users that define a sensor via the pressure-triplet)
 - stricter check for the status byte + better error return levels
 - drop the use of devm_kzalloc()
 - stick to the datasheet parameters while performing the measurement
    sequence

minor changes:
 - includes added and removed
 - rename generic 'buffer' variable to 'rx_buf'

I still included the memset patch for the reasons described in the v1 thread.
if you strongly consider that patch inadequate then please skip it.

Tested on two sensors - MPRLS0015PA0000SA and MPRLS0001BA00001A

Hi Petre,

I took a look at the whole series and didn't have anything to add to
Andy's review.

As we are somewhat near the end of the cycle, if you have time,
feel free to send a v3 sooner than the normal delay of 1ish weeks
(unless there is something you want to wait for more feedback on!)

I'll almost certainly take the lot for the merge window now rather
than trying to get the fixes in this cycle.

Thanks,

Jonathan
