From 813598e3b46601d6dd8d373e689f60f7c60fbb48 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 19 May 2015 23:34:00 +0200 Subject: sunxi: Use axp221 sid on a33 Unlike the A31 and the A23 the A33 actually has a SID inside the SoC again, but sid[3] is 0 (at least on some SoCs), so it is better to use the axp221 sid.
