Subject: [PATCH] usb: musb: Update FIFO mode_5_cfg to accomodate 4K
Date: Tue,  4 May 2010 14:32:02 +0530	[thread overview]
Message-ID: <1272963722-8659-1-git-send-email-ajay.gupta@ti.com> (raw)

FIFO table fifo_5_cfg was added so that it can be used as a
workaround for OMAP34x/35x errata which limits the FIFO space
uses to be within first 8K or next 8K.

Updating this table to accomodate an endpoint of 4K so that
the same table can be used for high bandwidth transfers as
used by some USB cameras.
