+Subject: [PATCH] clk: sunxi: factors: fix off-by-one masks
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The previous code would generate one bit too long masks, and was
+needlessly complicated. This patch replaces it by simpler code that can
+generate the masks correctly.

+Subject: [PATCH] clk: composite: .determine_rate support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This commit adds .determine_rate support to the composite clock. It will
+use the .determine_rate callback from the rate component if available,
+and fall back on the mux component otherwise. This allows composite
+clocks to enjoy the benefits of automatic clock reparenting.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+With the new factors infrastructure in place, we can unify apb1 and
+apb1_mux as a single clock now.

+Subject: [PATCH] clk: sunxi: declare OF clock provider
+
+Common clock framework allows to register clock providers to get called
+on of_clk_init() by using CLK_OF_DECLARE. This converts sunxi clock
+providers to make use of it and get rid of the mach specific clk init
+call. As sunxi has a bunch of independent clk provider nodes, we hook
+current clock init to board compatible to make it called once.

+
+Some important clocks may get disabled as a side effect of another clock
+being disabled, because they have no consumers. This patch implements a
+mechanism so those clocks can be claimed by the driver and therefore
+remain enabled at all times.
