* @ 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
