214c798ba1 net: phy: aquantia: do not return an error on clearing pending IRQs
The referenced commit added in .config_intr() the part of code which upon
configuration of the IRQ state it also clears up any pending IRQ. If
there were actually pending IRQs, a read on the IRQ status register will
return something non zero. This should not result in the callback
returning an error.

Fix this by returning an error only when the result of the
phy_read_mmd() is negative.

e11ef96d44 net: phy: aquantia: remove the use of .ack_interrupt()
In preparation of removing the .ack_interrupt() callback, we must replace
its occurrences (aka phy_clear_interrupt), from the 2 places where it is
called from (phy_enable_interrupts and phy_disable_interrupts), with
equivalent functionality.

This means that clearing interrupts now becomes something that the PHY
driver is responsible of doing, before enabling interrupts and after
clearing them. Make this driver follow the new contract.

6ab930df83 net: phy: aquantia: implement generic .handle_interrupt() callback
In an attempt to actually support shared IRQs in phylib, we now move the
responsibility of triggering the phylib state machine or just returning
IRQ_NONE, based on the IRQ status register, to the PHY driver. Having
3 different IRQ handling callbacks (.handle_interrupt(),
.did_interrupt() and .ack_interrupt() ) is confusing so let the PHY
driver implement directly an IRQ handler like any other device driver.
Make this driver follow the new convention.

e0f909bc3a net: switch to using PHY_INTERFACE_MODE_10GBASER rather than 10GKR
Switch network drivers, phy drivers, and SFP/phylink over to use the
more correct 10GBASE-R, rather than 10GBASE-KR. 10GBASE-KR is backplane
ethernet, which is 10GBASE-R with autonegotiation on top, which our
current usage on the affected platforms does not have.

The only remaining user of PHY_INTERFACE_MODE_10GKR is the Aquantia
PHY, which has a separate mode for 10GBASE-KR.

For Marvell mvpp2, we detect 10GBASE-KR, and rewrite it to 10GBASE-R
for compatibility with existing DT - this is the only network driver
at present that makes use of PHY_INTERFACE_MODE_10GKR.

ce64c1f77a net: phy: aquantia: add USXGMII support and warn if XGMII mode is set
So far we didn't support mode USXGMII, and in order to not break few
boards mode XGMII was accepted for the AQR107 family even though it
doesn't support XGMII. Add USXGMII support to the Aquantia PHY driver
and warn if XGMII mode is set.

v2:

74dcb4c1a5 net: phy: aquantia: add SGMII statistics
The AQR107 family has SGMII statistics counters. Let's expose them to
ethtool. To interpret the counters correctly one has to be aware that
rx on SGMII side is tx on ethernet side. The counters are populated
by the chip in 100Mbps/1Gbps mode only.

v2:
- add constant AQR107_SGMII_STAT_SZ
- add struct aqr107_priv to be prepared for more private data fields
- let aqr107_get_stat() return U64_MAX in case of an error

fb470f70fe net: phy: aquantia: add hwmon support
This adds HWMON support for the temperature sensor and the related
alarms on the 107/108/109 chips. This patch is based on work from
Nikita and Andrew. I added:
- support for changing alarm thresholds via sysfs
- move HWMON code to a separate source file to improve maintainability
- smaller changes like using IS_REACHABLE instead of ifdef
  (avoids problems if PHY driver is built in and HWMON is a module)

v2:
- remove struct aqr_priv
- rename header file to aquantia.h
v3:
- add conditional compiling of aquantia_hwmon.c
- improve converting sensor register values to/from long
- add helper aqr_hwmon_test_bit
