I will update the description in PATCHv7.

I guess this should be done in another patch? There's also a typo in
twl-family.txt's filename. My suggestion is to leave the patchset in
its current state. I will create another patch, which combines all
the twl4030 bindings descriptions into one file.

On of the following patches converts the driver to devm, which
results in complete removal of the twl4030_pwrbutton_remove
function.
