+/**
+ * struct smiapp_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_streamon: 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
+ * @value: 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
