omap2430 will handle the register writes to control module by itself.
So
a new address space to represent this control module register is added
to usb_otg_hs.

I do not have any objection/comment here, but I believe this is control
module address space required for USB module, right?
I am not sure this is right way of accessing control module space.
Actually Control Module Access required for drivers is one of the
blocking issue we have currently.
Also there was some effort put up by 'Konstantine' to convert Control
module to MFD driver, I haven't seen any further update on it. But it
would be good to check with him.
this was an agreement with Benoit since we already lost a couple merge
windows for this patchset. We agreed to wait until -rc4 for SCM driver
and if it wasn't ready, we'd go ahead with this and SCM author would fix
it up on a patch converting users to new SCM driver.
Tony, can I get your Acked-by to this patch so I can take it together
with the rest of the series ? Thanks
ps: I'll apply this to my 'musb' branch which is immutable, so it's safe
to merge it into your tree once I apply.
It would be best if this got acked by Benoit and Paul as they may
have some other patches queued up. I'll ack if they ack ;)
Benoit, care to ack this patch ???
Gosh, that's hard to ack something like that :-)
btw, that's not different than what's already in tree, the only
difference is that now hwmod knows about it...
But considering that the control module driver is not there yet, I have
no choice but accepting that one if we want to have the functionality
we've been waiting for years.
Could you just update the patch with a big disclaimer on top of the
address range to explain that this should not belong here and will be
removed ASAP, when the proper driver will be done.
sure, that's doable... Kishon, can you do this ASAP ? I want to send my
pull requests tomorrow at the latest.
Sure. Will send now.
Thanks
Kishon
