Interesting. I've sort of assumed <linux/clk.h> didn't get much use outside the embedded arch code (ARM, AVR32, SH pending, ...) so far ... there's no good technical reason for that of course! > > No, let's not complexify that pm_message_t mistake any further. > > I second that.

Even within one platform there can be board-specific diferences, and different chip revisions may work differently. - Dave _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
