Subject: [PATCH] pinctrl: berlin: fix BG2CD field widths
Date: Sat, 26 Sep 2015 21:03:21 -0400	[thread overview]
Message-ID: <56074059.10806@gmail.com> (raw)

The previous register layout was incorrect, many of the fields having
fewer bits than were needed to represent all their modes. The new layout
is taken from the bootloader source of a BG2CD device.
