What does it fix, why do you want this?

I posted the cam_enc_4xx board support. Now adding USB support, and I
have to configure this register as:

#define CONFIG_DV_USBPHY_CTL (USBPHY_SESNDEN | USBPHY_VBDTCTEN | \
                                USBPHY_PHY24MHZ)

so I need a possibility to configure this register ... and I could not
use DAVINCI_DM365EVM! (BTW: This define (so it seems to me) hides
board specific code, which should be cleaned up ... Sandeep?)

bye,
Heiko

No new reply on this since early august... Personally, I'd rather this 
patch came in a patchset where some other patch uses it.

Hmm.. Anyway I have to resend the cam_enc_4xx board port, as now the new
SPL Framework is in mainline, and my post used the old one. Also
I added in the meantime USB support for it, for which I needed this patch.
But actually I am wating for a new HW, so I can't test it ... and then
I post this patchset again with this patch in it! Can I add then your
"Acked-by" for this patch?

Thanks
Heiko
