please could you suggest the appropriate branch, because this patch is
based on mxc-master branch, where the watchdog is already pushed, see
http://git.pengutronix.de/?p=imx/linux-2.6.git;a=shortlog;h=refs/heads/mxc-master

Surely. Before patch submission I just checked that base address, size
and interrupt number are equal for i.MX31 and i.MX35 SoCs, and I've
found that in such cases the resources are defined using MX31 macros,
see imx_ssi_resources or mxc_usbhX_resources as reference.

Probably better to separate the devices.c file into two files? You see
one day I hope i.MX37 support will be included into the Linux kernel,
and it would be quite uncomfortable to support three kinds of peripheral
in a single file.
