Zhangfei Gao 1527058736 reset: hisilicon: add reset-hi3660
Add hi3660 reset driver
Example of dts usage:
	iomcu_rst: iomcu_rst_controller {
		compatible = "hisilicon,hi3660-reset";
		hisi,rst-syscon = <&iomcu>;
		#reset-cells = <2>;
	};

	i2c0: i2c@..... {
                ...
		resets = <&iomcu_rst 0x20 3>; /* offset: 0x20; bit: 3 */
                ...
        };

Philipp Zabel cddb480016 reset: hi6220: allow to compile test driver on other architectures
Also remove the RESET_CONTROLLER dependency, this Kconfig file is
included inside the menuconfig already.

Chen Feng 8768a26cea reset: hisilicon: Change to syscon register access
There are two reset controllers in hi6220 SoC:
The peripheral reset controller bits are part of sysctrl registers.
The media reset controller bits are part of mediactrl registers.

So change register access to syscon way.
And rename current reset controller to peripheral one.

Masahiro Yamada c41ef91f65 reset: hisilicon: check return value of reset_controller_register()
The newly added hisilicon reset driver missed the subsystem-wide
fixup by commit d1f15aa095 ("reset: check return value of
reset_controller_register()").  So fix it now.

Arnd Bergmann 70b3590f63 reset: hi6220: fix modular build
We need to include <linux/module.h> to build the driver as a loadable
module:

drivers/reset/hisilicon/hi6220_reset.c:108:1: warning: data definition has no type or storage class
 postcore_initcall(hi6220_reset_init);
