On TI's AM654/J721e SoCs, certain clocks can be gated/ungated by setting a single bit in SoC's System Control Module registers. Sometime more than one clock control can be in the same register. Add a driver to support such clocks using syscon framework. Driver currently supports controlling EHRPWM's TimeBase clock(TBCLK) for AM654 SoC.

This adds the clock driver support over TI System Control Interface.

If you wish to use clock resources from the PMMC firmware, say Y.

Otherwise, say N.

|
Forces the TI SCI clock driver to probe available clocks from the
|
|
firmware. By default, only the used clocks are probed from DT.
|
|
This is mostly only useful for debugging purposes, and will
|
|
increase the boot time of the device. If you want the clocks probed
|
|
from firmware, say Y. Otherwise, say N.
