Dear Andrew Murray,
> The musb driver defines and uses MUSB_CSR0_H_DIS_PING, however this
> bit is reserved on the DM36x. Thus this patch ensures that the
> reserved bit is not accesssed.
>
> It has been observed that some USB devices will fail to enumerate
> with errors such as 'error in inquiry' without this patch.
