Sounds good.

It feels a bit funky to me because we would still have code that is
omap-specific inside the "common" probe()/remove() calls.

I suggest to move everything that is omap-specific to a small omap
module that, once probed, would register itself with the common
hwspinlock framework (after initializing its hardware).

That small platfom-specific module probably doesn't have to sit in the
arch/ folder; we can follow established conventions like
mmc/i2c/gpio/spi/etc..

With that in hand, the hwspinlock would really be hardware-agnostic,
and then applying s/omap_hwspin/hwspin/ would be justified.

Does this sound reasonable to you ?

Thanks,
Ohad.
