[PATCH v7 0/2] net: macb: Wake-on-Lan magic packet GEM and MACB handling

[nicolas.ferre at microchip.com]

From: Nicolas Ferre <nicolas.ferre at microchip.com>

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.
