/**
* 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
