The SMC1 block on i.MX7ULP is already used as a clock provider in
imx7ulp.dtsi, but the corresponding dt-binding schema does not define
the required '#clock-cells' property. This results in CHECK_DTBS schema
validation errors.
Functionally, SMC1 controls the CPU run mode configuration:
- 00b: Normal Run (RUN)
- 10b: Very-Low-Power Run (VLPR)
- 11b: High-Speed Run (HSRUN)
These run modes determine the effective CPU operating point, and their
programming is tied to the OPP table.
Add the missing `#clock-cells` definition so the dt-binding schema is
consistent with the DTS and validates correctly.

|
The Multi-System Mode Controller (MSMC) is responsible for sequencing
|
|
the MCU into and out of all stop and run power modes. Specifically, it
|
|
monitors events to trigger transitions between power modes while
|
|
controlling the power, clocks, and memories of the MCU to achieve the
|
|
power consumption and functionality of that mode.
|
|
|
|
The WFI or WFE instruction is used to invoke a Sleep, Deep Sleep or
|
|
Standby modes for either Cortex family. Run, Wait, and Stop are the
|
|
common terms used for the primary operating modes of Kinetis
|
|
microcontrollers.
