Is there any update the v8 patchs for input cyapa trackpad drivers?

Thanks,
Dudley

> patch 2/13: add cyapa driver power management interfaces support.
>
> patch 3/13: add cyapa driver runtime power management interfaces support.
>
> patch 4/13: add cyapa key function interfaces in sysfs system.
> Including read firmware version, get production ID, read baseline,
> re-calibrate trackpad baselines and do trackpad firmware update.

> patch 5/13: add read firmware image and read raw trackpad device'

>
> patch 6/13: add gen3 trackpad device basic functions support.
>
> patch 7/13: add gen3 trackpad device firmware update function support.
