Jose Abreu 923587aafc clk/axs10x: Add I2S PLL clock driver
The ARC SDP I2S clock can be programmed using a
specific PLL.

This patch has the goal of adding a clock driver
that programs this PLL.

At this moment the rate values are hardcoded in
a table but in the future it would be ideal to
use a function which determines the PLL values
given the desired rate.

Binding for the AXS10X I2S PLL clock
This binding uses the common clock binding[1].
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
Required properties:
- compatible: shall be "snps,axs10x-i2s-pll-clock"
- reg : address and length of the I2S PLL register set.
- clocks: shall be the input parent clock phandle for the PLL.
- #clock-cells: from common clock binding; Should always be set to 0.
Example:
pll_clock: pll_clock {
compatible = "fixed-clock";
clock-frequency = <27000000>;
#clock-cells = <0>;
};
i2s_clock@100a0 {
compatible = "snps,axs10x-i2s-pll-clock";
reg = <0x100a0 0x10>;
clocks = <&pll_clock>;
#clock-cells = <0>;
};
