[U-Boot] [PATCH v2 4/9] dm: at91: Add platform data for GPIO on at91sam9260-based boards

Simon Glass sjg at chromium.org
Wed Oct 29 20:08:58 CET 2014


These boards all have the same GPIO arrangement, so add some common platform
data that can be used by all boards. Remove the configs which are no longer
required.

Signed-off-by: Simon Glass <sjg at chromium.org>

Changes in v2:
- Use PA/PB/PC instead of A/B/C for GPIO port names
