Changes in v2:
	- used defines MDIO_CTRL1_LPOWER and MDIO_PMA_CTRL1_SPEED1000
	  in mv88q222x_config_aneg_preinit
	- use genphy_c45_loopback
	- mv88q2xxx_read_status reads speed, master or slave state when
	  autonegotiation is enabled
	- added defines for magic values in mv88q222x_get_sqi

Changes in v3:
	- mv88q2xxx_read_status includes autonegotiation case
	- add support for 100BT1 and 1000BT1 linkmode advertisement
	- use mv88q2xxx_get_sqi and mv88q2xxx_get_sqi_max, remove
	  mv88q222x_get_sqi and mv88q222x_get_sqi_max
	- fix typo: rename mv88q2xxxx_get_sqi and mv88q2xxxx_get_sqi_max to
	  mv88q2xxx_get_sqi and mv88q2xxx_get_sqi
	- add define MDIO_MMD_PCS_MV_RX_STAT for magic value 0x8230, documented
	  in latest datasheets for both PHYs

Changes in V4:
	- clean up init sequence
	- separate patch for fixing typos in upstreamed code

Changes in V5:
	- add missing statics for mv88q222x_revb0_init_seq0 and
	  mv88q222x_revb0_init_seq1
	- fix typo in commit message: autonegotiation
	- fix ordering of Signed-off-by and Reviewed-by in commit messages
	- add interrupt support for link detection
	- add suspend / resume ops
	- add support for internal temperature sensor
	- add cable test support
	- call .soft_reset in mv88q2xxx_config_aneg, this makes
	  mv88q2xxx_config_aneg compatible for Marvell88Q222x devices and
	  remove mv88q222x_config_aneg which is then just duplicated code
	- cleanup mv88q2xxx_config_init and make it compatible with
	  Marvell88Q222x devices
	- move parts from mv88q222x_config_init to mv88q2xxx_config_init
	  that are applicable for all Marvell88Q2xxx devices.

Changes in V6:
	- add copyright and where the code is derived from (patch 5). Sorry
	  Andrew. It is already reviewed, but I think it is the right place.
	  Didn't remove the Reviewed-by because the changes doesn't touch any
	  code that is getting executed.
	- add HWMON dependeny in Kconfig (patch 8)
	- use IS_ENABLED(CONFIG_HWMON) instead of ifdef CONFIG_HWMON to support
	  hwmon built as module (patch 8)
	- drop shift constant MDIO_MMD_PCS_MV_TEMP_SENSOR3_INT_THRESH_SHIFT
	  and use FIELD_GET and FIELD_PREP instead(patch 8)
	- drop shift constant MDIO_MMD_PCS_MV_TDR_STATUS_DIST_SHIFT and use
	  FIELD_GET and FIELD_PREP instead (patch 9)
	- split previous patch 13 into two patches.
