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

* 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,

||||
