just realized that if (udphy->status != UDPHY_MODE_NONE) ret = rk_udphy_init(udphy); does the same, and we really don't need to disable and re-enable the phy's clocks that are the added via rk_udphy_disable and _setup. So will give it a day and send a v2 then. Heiko -- linux-phy mailing list linux-phy@lists.infradead.org https://lists.infradead.org/mailman/listinfo/linux-phy
