There are also additional four timers in the MCU domain do not have interrupts routable for Linux and are likely reserved by the software for the ESM module. Compared to am64, the timer clocks are different on am65. And the MCU timers are at a different IO address. Then j72 adds more timers compared to am65 with a total of 30 timers. And the j72 clocks are different. To avoid duplication for dtsi files, eventually we may want to consider adding timer specific shared dtsi files with the timer clocks mapped using SoC specific files in include/dt-bindings/clock. But let's get am65 timers usable first.
