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' Eddie James (2): iio: pressure: dps310: Refactor startup procedure iio: pressure: dps310: Reset chip if MEAS_CFG is corrupt drivers/iio/pressure/dps310.c | 277 +++++++++++++++++++++------------- 1 file changed, 173 insertions(+), 104 deletions(-) -- 2.31.1
