[PATCH v2 0/2] Add support for q50sn12072 and q54sn120a1

[Brian Chiang]

The Q54SN12072 and Q54SN120A1 are high-efficiency, high-density DC-DC power
module from Delta Power Modules.

The Q54SN12072, quarter brick, single output 12V. This product provides up
to 1200 watts of output power at 38~60V. The Q54SN12072 offers peak
efficiency up to 98.3%@54Vin.

The Q54SN120A1, quarter brick, single output 12V. This product provides up
to 1300 watts of output power at 40~60V. The Q54SN120A1 offers peak
efficiency up to 98.1%@54Vin.

Add support for them to q54sj108a2 driver.

Changes in v2:
- Drop Q50SN12072_DEBUGFS_VOUT_COMMAND debugfs entry
- Add .format[PSC_VOLTAGE_OUT] = linear explicitly to all three chip
  entries for consistency
- Replace hardcoded MFR_MODEL check (ret != 14 || strncmp("Q54SJ108A2"))
  with a loop over q54sj108a2_id[] using strncasecmp to support all
  three chip variants dynamically
- Remove of_device_get_match_data()/i2c_match_id() early chip_id path;
  derive chip_id exclusively from MFR_MODEL hardware read
- Remove unused .data fields from of_device_id entries
- Guard store_default, blackbox_erase, blackbox_set_offset, blackbox_read,
  and flash_key debugfs entries under psu->chip == q54sj108a2 check
- Add dev_notice() when configured device name differs from detected model
- Update MODULE_DESCRIPTION to "PMBus driver for Delta Q54SJ108A2 and
  compatibles"
- Fix commit message typo: "Q54SN12072" -> "Q50SN12072"
- Link to v1: https://lore.kernel.org/r/20250701-add-support-for-q50sn12072-and-q54sn120a1-v1-0-c387baf928cb@xxxxxxxxxxxx
