Subject: [PATCH RFC v4 0/6] ARM: pxa: GPIO descriptor conversions

Hello,

Small series to convert some of the board files in the mach-pxa directory
to use the new GPIO descriptor interface.

Most notably, the am200epd, am300epd and Spitz matrix keypad among
others are not converted in this series.
