Subject: [PATCH v3 0/4] hwmon: (sch56xx) Automatically load on supported hardware

The hardware monitoring solutions supported by the sch5627 and
sch5636 drivers are Fujitsu-specific.
After some online searching, i found out that the solution used
with the SCH5627 is called "Antiope" by Fujitsu, just like the
"Theseus" solution inside the SCH5636.
I also found out that "Antiope" and "Theseus" are listed as
DMI onboard devices on supported Fujitsu devices, so the
sch56xx_common module can be loaded automatically an check
for the DMI devices. However some devices like the Esprimo C700
have both devices, so after verifying that at least one onboard
device is present, sch56xx_common still has to detect which chip
is present.
This is safe however if at least one device is present.

Tested on a Fujitsu Esprimo P720.

Changes in v3:
- fix usleep_range using the same value as msleep

Changes in v2:
- fix unused variable issue reported by the kernel test robot
by assinging the platform device id list in sch5627/sch5636
to platform_driver->id_table.

Armin Wolf (4):
  hwmon: (sch56xx) Autoload modules on platform device creation
  hwmon: (sch56xx-common) Add automatic module loading on supported
    devices
  hwmon: (sch56xx-common) Replace msleep() with usleep_range()
  hwmon: (sch56xx-common) Replace WDOG_ACTIVE with WDOG_HW_RUNNING
