Subject: [RFC 09/12] omap: mcbsp: Move OMAP3+ wakeup enable/disable to omap_mcbsp_request/_free
Date: Fri,  1 Jul 2011 11:52:33 +0300	[thread overview]
Message-ID: <1309510356-27147-10-git-send-email-jhnikula@gmail.com> (raw)
In-Reply-To: <1309510356-27147-1-git-send-email-jhnikula@gmail.com>

There are only enable/disable wakeup behavior code left in
omap34xx_mcbsp_request/_free after hwmod conversion so it can be well moved
to generic omap_mcbsp_request/_free.

Remove also old comments about idle mode settings and HW bug workarounds
that were not updated during hwmod conversion.
