/** * struct ccs_quirk - quirks for sensors that deviate from SMIA++ standard * * @limits: Replace sensor->limits with values which can't be read from * sensor registers. Called the first time the sensor is powered up. * @post_poweron: Called always after the sensor has been fully powered on. * @pre_streamon: Called just before streaming is enabled. * @post_streamoff: Called right after stopping streaming. * @pll_flags: Return flags for the PLL calculator. * @init: Quirk initialisation, called the last in probe(). This is * also appropriate for adding sensor specific controls, for instance. * @reg_access: Register access quirk. The quirk may divert the access * to another register, or no register at all. * * -write: Is this read (false) or write (true) access? * -reg: Pointer to the register to access * -val: Register value, set by the caller on write, or * by the quirk on read * -return: 0 on success, -ENOIOCTLCMD if no register * access may be done by the caller (default read * value is zero), else negative error code on error * @flags: Quirk flags
