I've imported the series to OpenWrt and have heavily tested it on
various boards by now. Hence for the whole series:

Tested-by: Daniel Golle <daniel@...rotopia.org>

As already discussed off-list I've noticed that

[PATCH 6/9] Hook LED helper functions in mtk-ge.c

does NOT work as expected as it seems to be impossible to control the
PHY LEDs of the MT7531 switch individually -- all changes to *any* of the
MMD registers always affects *all* PHYs.

Hence, if you repost the series, I would recommend to drop 6/9 for now
until a solution for this has been found (such as controlling LEDs
switch-wide using the built-in GPIO controller, or somehow de-coupling
them and allow access to the individual LED registers like on MT7988)

After taking care of the minor corrections which have already been
pointed out by Andrew Lunn you may add

Acked-by: Daniel Golle <daniel@...rotopia.org>

to all patches except for 6/9.


Cheers


Daniel
