* Nishanth Menon <nm at ti.com> [230531 21:32]:
> There are 20 general purpose timers on j721e 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.
> 
> The odd numbered timers have the option of being cascaded to even
> timers to create a 64 bit non-atomic counter which is racy in simple
> usage, hence the clock muxes are explicitly setup to individual 32 bit
> counters driven off system crystal (HFOSC) as default.
> 
> These instantiation differs from J7200 and other SoCs with the device
> IDs and clocks involved for muxing.
