Thanks for the patch. I suggest you submit this patch for inclusion in
the upstream kernel. To do this, send it to:

Joel Stanley <joel@jms.id.au>
Andrew Jeffery <andrew@aj.id.au>
linux-arm-kernel@lists.infradead.org
linux-aspeed@lists.ozlabs.org
linux-kernel@vger.kernel.org

And I will consider it for merging.

From there I can backport it into the dev-4.13 tree.

Cheers,

Joel
