- drop timer1 in favor of main_timer0 in am64-main.dtsi.
Need to delete clock & power domain properties of main_timer1 in -r5.dts else won't boot. This is because timer_init is done during rproc_start to start System Firmware, but we can't do any clock/power-domain operations before System Firmware starts.
if that is the argument for main_uart0 and main_i2c0 main_gpio0 etc.
- please document in the r5.dts as well as to why we are
/delete-property/ power-domains. I think we feed in boardconfig etc by the time we get around to this, correct? if not, we might need to state that information - that without boardconfig being fed to the sysfw pm functions are'nt active.
I got rid of /delete-property/ for main_i2c0 and main_gpio0 and didn't see any ill effects. So will drop them from there. Looks like we need to have it only for main_uart0 and main_timer0. I'll add a comment for main_uart0.
