Why not call it directly? The intent was to capture the timestamp before the bus read, so it is as close as possible to the data ready event rather than after the regmap_bulk_read() over I2C/SPI. If that difference is not considered significant here, I'm happy to call it directly in v2. Thanks, Liu Yufei
