Hello, This patch adds support for doing internal offset correction for the proximity and gesture circuits. The correction value is written to the respective POFFSET_x or GOFFSET_x register depending on which direction we want to perform this calibration. For the proximity channel we apply the offset to both the DL and UR directions. And for the gesture channel we apply the offset to the respective U, D, L, R direction. Changes in v2: - Used IIO_CHAN_INFO_CALIBBIAS instead of exposing custom sysfs attributes - Used enum to choose between correct the offset registers - Corrected the formatting and style errors - Link to v1 : https://lore.kernel.org/linux-iio/20240707171357.709d9e35@jic23-huawei/ Regards, Abhash Abhash Jha (1): iio: light: apds9960: Add proximity and gesture offset calibration drivers/iio/light/apds9960.c | 69 +++++++++++++++++++++++++++++++++++- 1 file changed, 68 insertions(+), 1 deletion(-) -- 2.43.0
