Hi Angelo,
MT8188 is not the only SoC that will use bus protection for reset.
I checked with the owner of reset controller.
There are some reasons that they prefer to control bus protection by
each module which needs reset function individually. First, reset
function is only used by few modules. Second, bus protection register
for the same module is possibly different in each of SoCs. Finally, bus
protect bits are diverse, so it's not easy to implement in reset
controller driver.
Thanks,
Trevor
