+Subject: [PATCH 5/9] clk: sunxi: Add a driver for the PLL2
+
+The PLL2 on the A10 and later SoCs is the clock used for all the audio
+related operations.
+
+This clock has a somewhat complex output tree, with three outputs (2X, 4X
+and 8X) with a fixed divider from the base clock, and an output (1X) with a
+post divider.
+
+However, we can simplify things since the 1X divider can be fixed, and we
+end up by having a base clock not exposed to any device (or at least
+directly, since the 4X output doesn't have any divider), and 4 fixed
+divider clocks that will be exposed.
+
+This clock seems to have been introduced, at least in this form, in the
+revision B of the A10, but we don't have any information on the clock used
+on the revision A.

+Subject: [PATCH 6/9] clk: sunxi: pll2: Add A13 support
+
+The A13, unlike the A10 and A20, doesn't use a pass-through exception for
+the 0 value in the pre and post dividers, but increments all the values
+written in the register by one.
+
+Add an exception for both these cases to handle them nicely.

+Subject: [PATCH 9/9] clk: sunxi: pll2: Fix clock running too fast
+
+Contrary to what the datasheet says, the pre divider doesn't seem to be
+incremented by one in the PLL2, but just uses the value from the register,
+with 0 being a bypass.
+
+This fixes the audio playing too fast.
+
+Since we now have the same pre-divider flags, and the only difference with
+the A10 is the post-divider offset, also remove the structure to just pass
+the offset as an argument.
