/** |
|
* 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 |
|
* @value: Register value, set by the caller on write, or |
|
* by the quirk on read |
|
* |
|
* @flags: Quirk flags |
|
* |
|
* @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 |
