Hello,

Hi3519 soc is mainly used for ip camera and sport DV solutions. This patchset adds initial support
for Hi3519 soc. It includes clock driver, arch configuration, debug uart configuration and device tree.
It has been tested on hi3519 reference board.

Any comments will be appreciated!

Thanks!

+* Hisilicon Hi3519 Clock and Reset Generator(CRG)
+
+The Hi3519 CRG module provides clock and reset signals to various
+controllers within the SoC.
+
+This binding uses the following bindings:
+    Documentation/devicetree/bindings/clock/clock-bindings.txt
+    Documentation/devicetree/bindings/reset/reset.txt
+
+Required Properties:
+
+- compatible: should be one of the following.
+  - "hisilicon,hi3519-crg" - controller compatible with Hi3519 SoC.
+
+- reg: physical base address of the controller and length of memory mapped
+  region.
+
+- #clock-cells: should be 1.
+
+Each clock is assigned an identifier and client nodes use this identifier
+to specify the clock which they consume.
+
+All these identifier could be found in <dt-bindings/clock/hi3519-clock.h>.
+
+- #reset-cells: should be 2.
+
+A reset signal can be controlled by writing a bit register in the CRG module.
+The reset specifier consists of two cells. The first cell represents the
+register offset relative to the base address. The second cell represents the
+bit index in the register.
+
+Example: CRG nodes
+CRG: clock-reset-controller@12010000 {
+	compatible = "hisilicon,hi3519-crg";
+        reg = <0x12010000 0x10000>;
+        #clock-cells = <1>;
+        #reset-cells = <2>;
+};
+
+Example: consumer nodes
+i2c0: i2c@12110000 {
+	compatible = "hisilicon,hi3519-i2c";
+        reg = <0x12110000 0x1000>;
+        clocks = <&CRG HI3519_I2C0_RST>;*/
+        resets = <&CRG 0xe4 0>;
+};

This reset controller driver will be just used in some of hisilicon SOCs.
I'll add a specific config item for it like CONFIG_RESET_HISI. The config
item will be selected by default in SOCs needing this driver.

I'll also fix other issues in next version. Thank you!

Jiancheng.
