31 * struct smiapp_quirk - quirks for sensors that deviate from SMIA++ standard
33 * @limits: Replace sensor->limits with values which can't be read from
34 * sensor registers. Called the first time the sensor is powered up.
35 * @post_poweron: Called always after the sensor has been fully powered on.
36 * @pre_streamon: Called just before streaming is enabled.
37 * @post_streamon: Called right after stopping streaming.
38 * @reg_access: Register access quirk. The quirk may divert the access
39 * to another register, or no register at all.
41 * @write: Is this read (false) or write (true) access?
42 * @reg: Pointer to the register to access
43 * @value: Register value, set by the caller on write, or
44 * by the quirk on read
46 * @return: 0 on success, -ENOIOCTLCMD if no register
47 * access may be done by the caller (default read
48 * value is zero), else negative error code on error
