When I saw k230 a few minutes ago, I assumed you mean k210 since I
didn't found k230 support in linus tree now. After searching the
maillist, I found oh there is a k230 series which is similar to this
series, no pinctrl, no clk, no reset. Since the incomplete K230 initial
series hasn't been merged into Linus tree now, is it possible to drop
it so that we can avoid the same mistake for k230.

Yep previously I thought it was fine to use a fixed clock or dummy clock
during the initial patches, but I changed my mind now, especially after
Samuel complained the cv1800b reset dt changes.

The person who can bring the platfrom support to a well-moduled state,
IE, proper clk, pinctrl, reset drivers shows the passion, the code
contribution and solid understanding of the SoC, sure he/she is
definitely suited to maintain the SoC. I just don't think it's 
a good practice a person can became maintainer even w/o one LoC
contrubition to the SoC, because IMHO code contribution matters
for maintainership.
