Subject: [PATCH 06/15] dt-bindings: ufs: Add "max-gear" property for UFS device
Date: Sat, 29 Oct 2022 19:46:24 +0530 [thread overview]
Message-ID: <20221029141633.295650-7-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20221029141633.295650-1-manivannan.sadhasivam@linaro.org>
The maximum gear supported by the UFS device can be specified using the
"max-gear" property. This allows the UFS controller to configure the
TX/RX gear before starting communication with the UFS device.
