+	cp_intc_init();
+	irq_domain_add_simple(node, 0);

Take a look at the irq_domain patches that will be (probably) merged
in v3.4.  Instead of calling irq_domain_add_simple(), you should
migrate the whole interrupt controller to natively use an irq_domain
for hwirq <--> irq mapping.

I rebased my hole patchset to:

git://git.secretlab.ca/git/linux-2.6.git irqdomain/next
and reworked the arch/arm/mach-davinci/cp_intc.c irq driver to use
irq_domain, works good on the enbw_cmc board :-)

Waiting for your comment to my question to the
[RFC PATCH 7/7] ARM: davinci: add support for the am1808 based enbw_cmc board
patch, see:
http://www.mail-archive.com/linux-i2c at vger.kernel.org/msg07132.html

and resend the hole reworked patchserie. Is it OK, if I use the above
branch as base for sending this patchserie, or should I use another
tree/branch for it?

Ping?

bye,
Heiko
