Subject: [PATCH 0/2] usb: usb251xb: support usage case without I2C control
Date: Fri, 15 Aug 2025 10:55:38 +0800 [thread overview]
Message-ID: <20250815025540.30575-1-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.
