Subject: [PATCH v5 0/2] iio: pressure: dps310: Reset chip if MEAS_CFG is corrupt
Date: Mon, 15 Aug 2022 09:57:03 -0500 [thread overview]
Message-ID: <20220815145705.203017-1-eajames@linux.ibm.com> (raw)
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 v4:
- Just check for rc rather than rc < 0 in some cases
- Split declaration and init of rc
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'
