It seems to be no objection so far against my last suggestion to use regmap's mmio_clk() for named ipg clk only. So you may still consider about that. Anyway, I'd like to do thing in parallel. So I just simply tested it on my side and its works fine, it may still need to be tested by others though. Nicolin
