This patch series adds support for limiting the maximum high-speed gear and rate used by the UFS controller on Qualcomm platforms via device tree. Some automotive platforms, such as SA8155, require restricting the maximum gear or rate due to hardware limitations. To support this, the driver is extended to parse two new optional DT properties and apply them during initialization. The default behavior remains unchanged if these properties are not specified.
