+Subject: [PATCH] sun5i: Give PLL6 a sane initial value
+
+The upstream kernel does not override PLL values as set by power-on-reset
+and/or the bootloader if it can avoid doing so.
+
+The power-on-reset value for PLL6 is 2400MHz, which does not actually work,
+the kernel does not know this and 2400 / 48 is 50 MHz, so the kernel happily
+tries to use it as is for mmc.
+
+Set PLL6 to a working frequency so that the kernel can use it. This fixes
+mmc in the upstream kernel not working on sun5i.

+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.

+Fix:
+-code indentation
+-dram timings, the used cas and tpr0 - tpr2 were typical sun5i / sun7i

+-Properly sort boards.cfg entry
+-Add status led support
