It will simplify the dependencies if you drop this #include from this patch. In my comment on the cover letter, I suggested adding a patch that also switches the UART over to the new clock provider. That is the patch that should add this #include, since it will actually need #defines from the header. Doing it in that order means that we could merge this patch independently of the clock driver, and then merge the UART switch-over patch only after the driver (and headers) are merged.

I was planing to add UART DT part as separately patches (including the UARt's pinctrl part information) but as follow your suggestion, I could split the UART's clock DT info into separate patch, and send along with this series. > > Kevin > > . > -- To unsubscribe from this list: send the line "unsubscribe linux-clk" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
