[PATCH 0/4] hwmon: (msi_mystic_light) Add support for additional MSI motherboards

[Guenter Roeck <linux@roeck-us.net>]

This series extends the msi_mystic_light hwmon driver to support voltage
monitoring on three MSI 500- and 600-series motherboards:

  - MSI MAG B550M MORTAR MAX WIFI (MS-7C94, USB ID 1462:7c94)
  - MSI MAG B650 TOMAHAWK WIFI (MS-7D75, USB ID 1462:7d75)
  - MSI MAG B650M MORTAR WIFI (MS-7D76, USB ID 1462:7d76)

Unlike the 800-series MS-7E61 motherboard initially supported by the
driver, which exposes voltage readings synchronously via a
HID_REQ_GET_REPORT request on feature report 0xf0, the Mystic Light
controllers on these 500- and 600-series boards require sending an
output report to request sensor data and subsequently deliver the sensor
readings asynchronously via a HID raw event.

Patch 1 rearranges structures and per-board definitions so board-specific
read callbacks can be added without forward declarations.

Patch 2 drops redundant hid_hw_power() calls around sensor report reads,
since the HID device is already kept open for the lifetime of the driver
binding.

Patch 3 introduces a per-board read_report() callback in struct
msi_ml_board.

Patch 4 adds the output-report/raw-event read implementation, board
definitions, DMI/USB ID entries, and documentation for MS-7C94, MS-7D75,
and MS-7D76.

Guenter Roeck (4):
  hwmon: (msi_mystic_light) Rearrange code to simplify adding per-board
    read functions
  hwmon: (msi_mystic_light) Stop calling hid_hw_power()
  hwmon: (msi_mystic_light) Make sensor read function board specific
  hwmon: (msi_mystic_light) Add support for additional boards
