From 3e90772f76010c315474bde59eaca7cc4c94d645 Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Wed, 28 Dec 2011 13:10:04 +0200 Subject: [PATCH] ARM: at91: fix at91rm9200 soc subtype handling Currently setting it to PQFP changes subtype to BGA as subtypes are swapped in at91rm9200_set_type(). Wrong subtype causes GPIO bank D not to work at all. After this fix, subtype is still set as unknown. But board code should fill it in with proper value. Another information is thus printed. Bug discovery and first implementation made by Veli-Pekka Peltola.
