As discussed here: https://lore.kernel.org/all/ff8d6d14-6b48-4347-8525-e05eeb9721ff@xxxxxxxxx/ The ROHM BU27034NUC was cancelled before it entered mass-production. A replacement was developed and named to BU27034ANUC. (Note the added 'A' in the model name). The BU27034ANUC has several changes that make the old BU27034NUC driver unusable with it. I was told the old BU27034NUC should not be encountered anywhere. Hence, this series converts the rohm-bu27034.c to support the new BU27034ANUC instead of the obsoleted BU27034NUC. Additionally, the series adds a read-only entry for the HARDWAREGAIN to help understanding what part of the scale is contributed by the gain, and what by the integration time. This is useful when figuring out why some transitions from one 'scale' to other are failing. Revision history: v1 => v2: - Split the one large patch to patches 3 - 6 for easier review. (Please let me know if you wish me to squash them to one). - Introduce new compatible for the BU27034ANUC and drop the old one. - Add styling fixes as suggested by Jonathan - Fix the lux calculation coefficient selection logic link to v1: https://lore.kernel.org/all/cover.1718013518.git.mazziesaccount@xxxxxxxxx/ --- Matti Vaittinen (7): dt-bindings: iio: BU27034 => BU27034ANUC dt-bindings: iio: rename bu27034 file bu27034: ROHM BU27034NUC to BU27034ANUC bu27034: ROHM BU27034NUC to BU27034ANUC drop data2 bu27034: ROHM BU27034ANUC correct gains and times bu27034: ROHM BU27034ANUC correct lux calculation iio: bu27034: Add a read only HWARDWAREGAIN ...ohm,bu27034.yaml => rohm,bu27034anuc.yaml} | 11 +- drivers/iio/light/rohm-bu27034.c | 343 +++++------------- 2 files changed, 89 insertions(+), 265 deletions(-) rename Documentation/devicetree/bindings/iio/light/{rohm,bu27034.yaml => rohm,bu27034anuc.yaml} (66%) base-commit: 1613e604df0cd359cf2a7fbd9be7a0bcfacfabd0 -- 2.45.1 -- Matti Vaittinen, Linux device drivers ROHM Semiconductors, Finland SWDC Kiviharjunlenkki 1E 90220 OULU FINLAND ~~~ "I don't think so," said Rene Descartes.
