I'm having problems applying this patch - I don't have the above context
lines in my tree, or anything remotely resembling them. Neither can I
find anything remotely similar in mainline.
What did you generate this patch against? It can't be v3.11-rc6 as you
put in your KernelVersion: line for the patch system.
Your diff above says that this was generated against blob 814d224, which
doesn't exist in mainline either. Neither does it seem to appear in
my build tree which includes arm-soc's for-next branch.

Because there's some optimization on debug ll in your tree, I only find those
commits in linux-next git tree. So I based this commit in linux-next.
Could you help me to figure out which branch should I base in your git tree?
Since I can't find a right one.
Regards

+Device Tree Clock bindings for arch-hi3xxx
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+All the mux, gate & divider are in clock container of DTS file.
+
+Required properties for mux clocks:
+ - compatible : shall be "hisilicon,clk-mux".
+ - clocks : shall be the input parent clock phandle for the clock. This should
+ be the reference clock.
+ - clock-output-names : shall be reference name.
+ - #clock-cells : from common clock binding; shall be set to 0.
+ - reg : the mux register address. It should be the offset of the container.
+ - clkmux-mask : mask bits of the mux register.
+ - clkmux-table : array of mux select bits.
+
+Optional properties for mux clocks:
+ - clkmux-hiword-mask : indicates that the bit[31:16] are the hiword mask
+ of mux selected bits (bit[15:0]). The bit[15:0] is valid only when
+ bit[31:16] is set.
+
+
+
+Required properties for gate clocks:
+ - compatible : shall be "hisilicon,clk-gate".
+ - clocks : shall be the input parent clock phandle for the clock. This should
+ be the reference clock.
+ - clock-output-names : shall be reference name.
+ - #clock-cells : from common clock binding; shall be set to 0.
+ - reg : the mux register address. It should be the offset of the container.
+ - clkgate : bit index to control the clock gate in the gate register.
+
+Optional properties for gate clocks:
+ - clkgate-inverted : it indicates that setting 0 could enable the clock gate
+ and setting 1 could disable the clock gate.
+ - clkgate-seperated-reg : it indicates that there're three continuous
+ registers (enable, disable & status) for the same clock gate.
+
+
+
+Required properties for divider clocks:
+ - compatible : shall be "hisilicon,clk-div".
+ - clocks : shall be the input parent clock phandle for the clock. This should
+ be the reference clock.
+ - clock-output-names : shall be reference name.
+ - reg : the divider register address. It should be the offset of the
+ container.
+ - clkdiv-mask : mask bits of the divider register.
+ - clkdiv-min : the minimum divider of the clock divider.
+ - clkdiv-max : the maximum divider of the clock divider.
+
+Optional properties for divider clocks:
+ - clkdiv-hiword-mask : indicates that the bit[31:16] are the hiword mask
+ of divider selected bits (bit[15:0]). The bit[15:0] is valid only when
+ bit[31:16] is set.

To: linux-arm-kernel
Add board support with device tree for Hisilicon Hi36xx/Hi37xx platform.
Changelog:
v3:
1. Remove .map_io() in DT machine descriptor. Since debug_ll_io_init()
is called by default.
2. Remove .init_machine() in DT machine descriptor. Since
of_platform_populate() is called by default in DT mode.
v2:
1. Remove .init_irq() in DT machine descriptor. Since irqchip_init()
is called by default in DT mode.
