Subject: [PATCH v2 0/2] usb: usb251xb: support usage case without I2C control
Date: Tue, 19 Aug 2025 08:22:14 +0800	[thread overview]
Message-ID: <20250819002217.30249-1-jszhang@kernel.org> (raw)

Refactor so that register writes for configuration are only performed if
the device has a i2c_client provided and also register as a platform
driver. This allows the driver to be used to manage GPIO based control
of the device.

Since v1:
 - make the modern pm macros usage a separate patch
 - use pm_sleep_ptr instead of pm_ptr for usb251xb_plat_pm_ops, because
   this ops is for PM_SLEEP only.

  usb: usb251xb: use modern PM macros
  usb: usb251xb: support usage case without I2C control
