Subject: Re: haptics devices linux driver support

Hi,

There's three types as I know,

1) just GPIO enable motor
2) GPIO & PWM motor.
3) I2C based GPIO & PWM motor.

Frankly we made a motor framework at kernel. but I 'm not sure motor
is right naming or not.
I think we need new framework. since it's not input device.

Thank you,
Kyungmin Park
