Subject: [PATCH net-next v4 0/9] 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.

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.
	  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, \
				timeout_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 <andrew@...n.ch>, 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
	  again.
	- 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.
