I dunno, in arm land the various platform maintainers take care of this kind of thing for their own platforms. That hasn't happened (yet?) for riscv. I've probably taken most SoC support things like this recently.

It's not a huge driver (~20KB), but it all adds up. cheers _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv ^ permalink raw reply [flat|nested] 5+ messages in thread

Good point. Marek - could you respin as module? thanks, drew _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv ^ permalink raw reply [flat|nested] 5+ messages in thread
