Where is any binding doc for this? Why is this a separate patch?

The ARM SCMI device tree binding specification is located at 
./Documentation/devicetree/bindings/firmware/arm,scmi.yaml.

Certain secure clocks on the T7 rely on the ARM SCMI driver stack, which 
is officially supported by ARM.

The kernel-side SCMI client implementation resides in 
./drivers/firmware/arm_scmi/.

To enable ARM SCMI on T7, three components are needed:

- Kernel-side definition of ARM SCMI clock indices (this patch addresses 
this component);
- SCMI server implementation in the ARM Trusted Firmware (ATF) running 
at Exception Level 3 (EL3), which has been integrated into the bootloader;
- Device Tree Source (DTS) configuration for ARM SCMI clock nodes (the 
DTS changes will be submitted after the T7 clock driver patches are 
merged upstream).

Best regards,
Krzysztof
