[PATCH v4 0/2] iio: pressure: dps310: Reset chip if MEAS_CFG is corrupt

Posted by Eddie James 3 years, 8 months ago

Corruption of the MEAS_CFG register has been observed soon after
system boot. In order to recover this scenario, check MEAS_CFG if
measurement isn't ready, and if it's incorrect, reset the DPS310
and execute the startup procedure. Include a patch to move the
startup procedure into a function.

Changes since v3:
 - Don't check regmap* return codes for < 0
 - Fix comment spelling

Changes since v2:
 - Add some comments
 - Fix the clunky control flow

Changes since v1:
 - Separate into two patches
 - Rename 'dps310_verify_meas_cfg' to 'dps310_check_reset_meas_cfg'
