Subject[PATCH net-next v3 0/7] 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.

v2 -> v3:
- modify the parameter order of newly added functions.
phy_read_mmd_poll_timeout(val, cond, sleep_us, timeout_us, \
phydev, devaddr, regnum)
phy_read_mmd_poll_timeout(phydev, devaddr regnum, val, cond, \
sleep_us, timeout_us)

phy_read_poll_timeout(val, cond, sleep_us, timeout_us, \
phydev, regnum)
phy_read_poll_timeout(phydev, regnum, val, cond, sleep_us, \

v1 -> v2:
- passed a phydev, device address and a reg to replace args...
parameter in phy_read_mmd_poll_timeout() by Andrew Lunn 's
suggestion in patch 3. Andrew Lunn <>, Thanks
very much for your help!
- also in patch 3, handle phy_read_mmd return an error(the return
value < 0) in phy_read_mmd_poll_timeout(). Thanks Andrew
- in patch 6, pass a phydev and a reg to replace args...
parameter in phy_read_poll_timeout(), and also handle the
phy_read() function's return error.
