Subject: [RFC PATCH 0/3] usb: Add generic repeater framework and SM8550 driver
Date: Wed, 16 Nov 2022 14:30:16 +0200 [thread overview]
Message-ID: <20221116123019.2753230-1-abel.vesa@linaro.org> (raw)
This patchset adds a generic USB repeater framework to be used by
platforms that have eUSB2 support and want to have USB 2.0 compliance.
In such cases there is a device between the eUSB2 PHY and the actual
connector. That device is basically a repeater and the most important
thing it does is to level shift in both directions. Such a device needs
to be controlled in software usually by the PHY or by the HC.
So add a generic framework with basic ops to allow consumer drivers
to get a phandle to it and to control it.
Also add the SM8550 PMIC eUSB2 repeater which uses the generic
framework.
