Russell King says:

====================
Fix 88x3310 leaving power save mode

This series fixes a problem with the 88x3310 PHY on Macchiatobin
coming out of powersave mode noticed by Matteo Croce. It seems
that certain PHY firmwares do not properly exit powersave mode,
resulting in a fibre link not coming up.

The solution appears to be to soft-reset the PHY after clearing
the powersave bit.

We add support for reporting the PHY firmware version to the kernel
log, and use it to trigger this new behaviour if we have v0.3.x.x
or more recent firmware on the PHY. This, however, is a guess as
the firmware revision documentation does not mention this issue,
and we know that v0.2.1.0 works without this fix but v0.3.3.0 and
later does not.

Merge branch 'introduce-read_poll_timeout'

Dejin Zheng says:

====================
introduce read_poll_timeout

This patch sets is introduce read_poll_timeout macro, it is an extension
of readx_poll_timeout macro. the accessor function op just supports only
one parameter in the readx_poll_timeout macro, but this macro can
supports multiple variable parameters for it. so functions like
phy_read(struct phy_device *phydev, u32 regnum) and
phy_read_mmd(struct phy_device *phydev, int devad, u32 regnum) can
use this poll timeout framework.

the first patch introduce read_poll_timeout macro, and the second patch
redefined readx_poll_timeout macro by read_poll_timeout(), and the other
patches are examples using read_poll_timeout macro.

v6 -> v7:
- add a parameter to supports that it can sleep some time
before read operation in read_poll_timeout macro.
- add prefix with double underscores for some variable to avoid
any variable re-declaration or shadowing in patch 3 and patch
7.
v5 -> v6:
- add some check to keep the code more similar in patch 8
v4 -> v5:
- add some msleep() before call phy_read_mmd_poll_timeout() to
keep the code more similar in patch 6 and patch 9.
- add a patch of drop by v4, it can add msleep before call
phy_read_poll_timeout() to keep the code more similar.
v3 -> v4:
- add 3 examples of using new functions.
- deal with precedence issues for parameter cond.
- drop a patch about phy_poll_reset() function.
v2 -> v3:
- modify the parameter order of newly added functions.
