I defer to PHY experts for review. Coincidentally the first Marvell
flag appears dead, nobody sets it:

$ git grep MARVELL_PHY_M1145_FLAGS_RESISTANCE
drivers/net/phy/marvell.c:      if (phydev->dev_flags & MARVELL_PHY_M1145_FLAGS_RESISTANCE) {
include/linux/marvell_phy.h:#define MARVELL_PHY_M1145_FLAGS_RESISTANCE  0x00000001
$

unless it's read from DT under different name or something.


Once you get some reviews please wait for net-next to open:

http://vger.kernel.org/~davem/net-next.html

and repost. It should happen the week of Jan 24th. When you repost
please drop the first patch, I believe Russell does not like the BIT()
macro, his opinion overrides checkpatch.

Thanks!
