* Rockchip SPDIF transceiver
The S/PDIF audio block is a stereo transceiver that allows the
processor to receive and transmit digital audio via an coaxial cable or
a fibre cable.
Required properties:
- compatible: should be one of the following:
- "rockchip,rk3066-spdif"
- "rockchip,rk3188-spdif"
- "rockchip,rk3228-spdif"
- "rockchip,rk3288-spdif"
- "rockchip,rk3328-spdif"
- "rockchip,rk3366-spdif"
- "rockchip,rk3368-spdif"
- "rockchip,rk3399-spdif"
- reg: physical base address of the controller and length of memory mapped
region.
- interrupts: should contain the SPDIF interrupt.
- dmas: DMA specifiers for tx dma. See the DMA client binding,
Documentation/devicetree/bindings/dma/dma.txt
- dma-names: should be "tx"
- clocks: a list of phandle + clock-specifier pairs, one for each entry
in clock-names.
- clock-names: should contain following:
- "hclk": clock for SPDIF controller
- "mclk" : clock for SPDIF bus
Required properties on RK3288:
- rockchip,grf: the phandle of the syscon node for the general register
file (GRF)
Example for the rk3188 SPDIF controller:
spdif: spdif@1011e000 {
compatible = "rockchip,rk3188-spdif", "rockchip,rk3066-spdif";
reg = <0x1011e000 0x2000>;

Each iteration of the Net DIM algorithm follows these steps:

Net DIM API exposes the main function net_dim().
This function is the entry point to the Net
DIM algorithm and has to be called every time the driver would like to check if
it should change interrupt moderation parameters. The driver should provide two
data structures: struct dim and struct dim_sample. Struct dim
data structures: :c:type:`struct dim <dim>` and
:c:type:`struct dim_sample <dim_sample>`. :c:type:`struct dim <dim>`
describes the state of DIM for a specific object (RX queue, TX queue,
other queues, etc.). This includes the current selected profile, previous data
samples, the callback function provided by the driver and more.
Struct dim_sample describes a data sample, which will be compared to the
