+Subject: [PATCH] sun5i: Tweak pll6 init value
+
+There are multiple ways to get 600 MHz from PLL6, the sun5i ccmu is very
+similar to the sun4i and sun7i ccmu.
+
+This commit changes the PLL6 initialization we do for sun5i to make the PLL6
+reg value match that of sun4i and sun7i. This also makes it closer to the
+sun5i power on default, as we are now only changing the K-factor from 3 to 1.
