/*
|
|
* There are 8 controls available:
|
|
* 4 gain controls, sliders, for each of the BAYER components: R, B, GR, GB.
|
|
* These gains are multipliers for each component, in format unsigned 0:4:9 with
|
|
* a default value of 512 (1.0 multiplier).
|
|
* 4 offset controls, sliders, for each of the BAYER components: R, B, GR, GB.
|
|
* These offsets are added/substracted from each component, in format signed
|
|
* 1:12:0 with a default value of 0 (+/- 0)
|
|
*
|
|
* To expose this to userspace, added 8 custom controls, in an auto cluster.
|
|
*
|
|
* To summarize the functionality:
|
|
* The auto cluster switch is the auto white balance control, and it works
|
|
* like this:
|
|
* AWB == 1: autowhitebalance is on, the do_white_balance button is inactive,
|
|
* the gains/offsets are inactive, but volatile and readable.
|
|
* Thus, the results of the whitebalance algorithm are available to userspace to
|
|
* read at any time.
|
|
* AWB == 0: autowhitebalance is off, cluster is in manual mode, user can
|
|
* configure the gain/offsets directly.
|
|
* More than that, if the do_white_balance button is
|
|
* pressed, the driver will perform one-time-adjustment, (preferably with color
|
|
* checker card) and the userspace can read again the new values.
|
|
*
|
|
* With this feature, the userspace can save the coefficients and reinstall them
|
|
* for example after reboot or reprobing the driver.
