Merge miscellaneous libnvdimm updates for 4.21 

* Use common helpers, bitmap_zalloc() and kstrndup(), to replace open
  coded versions.
* Clarify the comments around hotplug vs initial init case for the nfit
  driver.
* Cleanup the libnvdimm init path.

Configuration of common clocks, which affect multiple consumer devices can

be similarly specified in the clock provider node.



==Protected clocks==



Some platforms or firmwares may not fully expose all the clocks to the OS, such

as in situations where those clks are used by drivers running in ARM secure

execution levels. Such a configuration can be specified in device tree with the

protected-clocks property in the form of a clock specifier list. This property should

only be specified in the node that is providing the clocks being protected:



   clock-controller@a000f000 {

        compatible = "vendor,clk95;

        reg = <0xa000f000 0x1000>

device-tree bindings for rockchip VPU codec



Rockchip (Video Processing Unit) present in various Rockchip platforms,

such as RK3288 and RK3399.



Required properties:

- compatible: value should be one of the following

		"rockchip,rk3288-vpu";

		"rockchip,rk3399-vpu";

- interrupts: encoding and decoding interrupt specifiers

- interrupt-names: should be "vepu" and "vdpu"

- clocks: phandle to VPU aclk, hclk clocks

- clock-names: should be "aclk" and "hclk"

- power-domains: phandle to power domain node

- iommus: phandle to a iommu node



Example:

SoC-specific DT entry:

	vpu: video-codec@ff9a0000 {

		compatible = "rockchip,rk3288-vpu";

		reg = <0x0 0xff9a0000 0x0 0x800>;

		interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>,

			     <GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>;

		interrupt-names = "vepu", "vdpu";

		clocks = <&cru ACLK_VCODEC>, <&cru HCLK_VCODEC>;

		clock-names = "aclk", "hclk";

		power-domains = <&power RK3288_PD_VIDEO>;

		iommus = <&vpu_mmu>;
