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.

@ -168,3 +168,19 @@ a shared clock is forbidden.
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>
#clocks-cells = <1>;
...
protected-clocks = <UART3_CLK>, <SPI5_CLK>;
};

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>;

* descendant queues with at least one request queued. This
* number is used to decide whether a scenario is symmetric.
* For a detailed explanation see comments on the computation
* of the variable asymmetric_scenario in the function
* bfq_better_to_idle().
*
* However, it is hard to compute this number exactly, for
* groups with multiple descendant processes. Consider a group
* that is inactive, i.e., that has no descendant process with
* pending I/O inside BFQ queues. Then suppose that
* num_groups_with_pending_reqs is still accounting for this
* group, because the group has descendant processes with some
* I/O request still in flight. num_groups_with_pending_reqs
* should be decremented when the in-flight request of the
* last descendant process is finally completed (assuming that
* nothing else has changed for the group in the meantime, in
* terms of composition of the group and active/inactive state of child
* groups and processes). To accomplish this, an additional
* pending-request counter must be added to entities, and must
* be updated correctly. To avoid this additional field and operations,
* we resort to the following tradeoff between simplicity and
* accuracy: for an inactive group that is still counted in
* num_groups_with_pending_reqs, we decrement
* num_groups_with_pending_reqs when the first descendant
* process of the group remains with no request waiting for
* completion.
*
* Even this simpler decrement strategy requires a little
* carefulness: to avoid multiple decrements, we flag a group,
* more precisely an entity representing a group, as still
* counted in num_groups_with_pending_reqs when it becomes
* inactive. Then, when the first descendant queue of the
* entity remains with no request waiting for completion,
* num_groups_with_pending_reqs is decremented, and this flag
* is reset. After this flag is reset for the entity,
* num_groups_with_pending_reqs won't be decremented any
* longer in case a new descendant queue of the entity remains
* with no request waiting for completion.
