Hi,
Here is the second part of support for WoL magic-packet on the current macb driver. 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
