[PATCH v11 0/6] enable hi3xxx SoC

[Haojian Zhuang]

v11:
 1. Add comments on iotable.
 2. Use dummy clock in DTS. Remove common clock binding in DTS file. Clock driver will be in another patchset.

v10:
 1. Use static IO mapping in Hi3xxx.
 2. Totally drop to support of Hi3716.
 3. Rename smp-off property to smp-offset.
 4. Remove hardcoding in hotplug driver.

v9:
 1. Clean code in DTS file according to Olof's comments.
 2. Since debug ll patch is going through Russell's tree, remove it
 from this patch set.

 v8:
 1. Drop to support CLK_GATE_SEPERATED_REG in common clock gate driver.
 Support this feature in hi3xxx clock driver.
 2. Clean unnecessary device node in DTS.
 3. Define all clocks in hi3620-clk.dtsi. And all clock nodes are defined
 in the clocks node.
 4. Fix the clock gate & clock mux for timer.
 5. Rename timer0~4 to dual_timer0~4 in DTS file. It's used to make
 name clearer.

 v7:
 1. Add hi3xxx_defconfig.
 2. Use reg property in clock node.
 3. Drop origin clock divider table.
 4. Reuse clock divider register helper.
 5. Reuse clock gate register helper.
 6. Append CLK_GATE_SEPERATED_REG flag in order to support Hisilicon
    Hi3620 SoC.
 7. Rebase DEBUG_LL for Hi3xxx.
 8. Add more clock node in DTS file.

 v6:
 1. Remove hisilicon string from properties in clock driver.
 2. Replace array by pointer in clock driver. Since only sctrl parent
    node exists at this time.

 v5:
 1. Remove HIWORD clk patches since they're merged into clk git tree.
 2. Set hisilicon,clk-reset property of clkgate node is optional.
 3. Update on commandline args in DTS file. Remove earlyprintk, mem, nfs.
 4. Move gpio-keys out of amba node in DTS file.

 v4:
 1. Add clk gate with HIWORD mask for Rockchip.
 2. Update comments and code of HIWORD flags for mux/divider.
 3. Append a mux without HIWORD mask in Hisilicon 3620.
 4. Fix the pinmux setting in Hi4511.

 v3:
 1. Use clk_register_mux_table().

 v2:
 1. Reuse mux & divider driver. So append CLK_MUX_HIWORD_MASK &
 CLK_DIVIDER_HIWORD_MASK for Hi3620 SoC.
 2. Fix system timer running too fast because wrong divider is choosen.
 3. Remove .init_irq in DT machine descriptor.
