This one is addressing the bulk of the feature and is based on current net-next/master. MACB and GEM code must co-exist and as they don't share exactly the same register layout, I had to specialize a bit the suspend/resume paths and plug a specific IRQ handler in order to avoid overloading the "normal" IRQ hot path. These changes were tested on both sam9x60 which embeds a MACB+FIFO controller and sama5d2 which has a GEM+packet buffer type of controller. Best regards, Nicolas Changes in v6: - rebase on net-next/master now that the "fixes" patches of the series are merged in both net and net-next. - GEM addition and MACB update to finish the support of WoL magic-packet on the two revisions of the controller. These 2 patches were last posted in v3 series.
