Hi Michal,

see my patch set, that I've already submitted. The patches are based on
your patch set from last week. I've create a bundle on patchwork:

http://patchwork.ozlabs.org/bundle/rexut/microblaze-fdt/

Further you will need a QnD hack to avoid a compilation error due to
type conflicts (I've not explored here, not yet):

In file included from key_matrix.c:28:
include/malloc.h:364: error: conflicting types for 'memset'
include/linux/string.h:71: error: previous declaration of 'memset' was
here
include/malloc.h:365: error: conflicting types for 'memcpy'
include/linux/string.h:74: error: previous declaration of 'memcpy' was
here


Here is the QnD hack:


diff --git a/drivers/input/Makefile b/drivers/input/Makefile
index 5c831b2..5efeeb3 100644
--- a/drivers/input/Makefile
+++ b/drivers/input/Makefile
@@ -32,7 +32,7 @@ COBJS-y += keyboard.o pc_keyb.o

endif
COBJS-y += input.o
-COBJS-$(CONFIG_OF_CONTROL) += key_matrix.o
+#COBJS-$(CONFIG_OF_CONTROL) += key_matrix.o

COBJS  := $(COBJS-y)
SRCS   := $(COBJS:.o=.c)




br,
Stephan
