smc911x irq sense request and MPR2 board support
Markus Brunner [Mon, 20 Aug 2007 06:36:50 +0000 (08:36 +0200)]
Hi,

this are the changes to the smc911x driver, which were necessary
to get it running on the Magic Panel R2 (smsc9115).
It is a SH3-DSP based board. The other patches are available on
the linuxsh-dev mailinglist.
http://marc.info/?l=linuxsh-dev&r=1&b=200708&w=2

It was necessary to set the irq sense to low level.
Therefor the SMC_IRQ_SENSE define was added.
How are the chances for inclusion in 2.6.24?
