Thank you for working on this! It looks good to me.
Do we have a plan how to merge all this?
Nothing (regulator, nor interconnect) will ever get enabled by Kconfig unless
the drivers/soc/mediatek patches are picked (or COMPILE_TEST!).... so I guess
we can just pick per-subsystem and call it a day :-)
As for the bindings, patch [3/7] *depends on* [1/7] and [2/7], but there is no
reverse dependency (so 1-2 can be picked, no warnings).
Otherwise I can pick all bindings, or.... whatever is easier for you :-)
Cheers,
Angelo
Thanks,
Georgi
