[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

GPIO subsystem. To avoid adding more and get rid of existing duplication
extend TODO.

 In some cases it makes sense to create a GPIO chip from the local driver
 for a few GPIOs. Those should stay where they are.
 
+At the same time it makes sense to get rid of code duplication in existing or
+new coming drivers. For example, gpio-ml-ioh should be incorporated into
+gpio-pch. In similar way gpio-intel-mid into gpio-pxa.
