Hello everyone, I wanted to refresh my voice coil lens patchset before we have more voice coil lens controller drivers. The VOCUS_ABSOLUTE control really is not a best control ID to control a voice coil driver's current. There may be additional controls in the class: the hardware I'm familiar with provides other controls (PWM vs. linear mode, resonance frequency and ringing compensation formula to name a few) but I'm not fully certain they're something that even should be told to the user --- let alone giving the user write access to them. My expectation is still that there will be more controls in the class. The PWM / linear mode might be one candidate: PWM saves power but it may cause other issues. These other issues might be something to ignore, depending on the use case. That will be anyway left for the future. since v2: - Don't remove the newline after control class definitions. - Move all ad5820 related changes to the second patch. Some were accidentally left to the patch adding the new control class. -- Kind regards, Sakari
