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 v7: - Release the spinlock before exiting macb_suspend/resume in case of error changing IRQ handler 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. History of previous changes already added to git commit message here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f9f41e3db40ee8d61b427d4d88c7365d968052a9 Nicolas Ferre (2): net: macb: WoL support for GEM type of Ethernet controller net: macb: Add WoL interrupt support for MACB type of Ethernet controller drivers/net/ethernet/cadence/macb.h | 3 + drivers/net/ethernet/cadence/macb_main.c | 191 +++++++++++++++++++---- 2 files changed, 167 insertions(+), 27 deletions(-) -- 2.27.0
