Subject: [PATCH 1/7] dt-bindings: phy: samsung,usb3-drd-phy: add gs101 compatible
Date: Tue, 23 Apr 2024 18:06:03 +0100 [thread overview]
Message-ID: <20240423-usb-phy-gs101-v1-1-ebdcb3ac174d@linaro.org> (raw)
In-Reply-To: <20240423-usb-phy-gs101-v1-0-ebdcb3ac174d@linaro.org>
Add a dedicated google,gs101-usb31drd-phy compatible for Google Tensor
gs101 SoC.
It needs additional clocks enabled for register access, and additional
memory regions (PCS & PMA) are required for successful configuration.
Signed-off-by: André Draszik <andre.draszik@linaro.org>
