Subject: [PATCH v2 09/22] mfd: omap-usb-tll: Add OMAP5 revision and HSIC support
Date: Wed, 28 Nov 2012 16:48:57 +0200 [thread overview]
Message-ID: <1354114150-11941-10-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1354114150-11941-1-git-send-email-rogerq-l0cyMroinI0@public.gmane.org>
The TLL module on OMAP5 has 3 channels.
HSIC mode requires the TLL channel to be in Transparent UTMI mode.
