* Nishanth Menon <nm@...com> [230531 21:32]:
> There are 20 general purpose timers on j721s2 that can be used for
> things like PWM using pwm-omap-dmtimer driver. There are also
> additional ten timers in the MCU domain which are meant for MCU
> firmware usage and hence marked reserved by default.
> 
> Though the count is similar to J721e/J7200, the device IDs and clocks
> used in j721s2 are different with the option of certain clocks having
> options of additional clock muxes. Since there is very minimal reuse,
> it is cleaner to integrate as part of SoC files itself. The defaults
> are configured for clocking the timers from system clock(HFOSC0).
