If anyone has any objections, please let me know. ------------------ From: Xu Yang commit b15ee09ddb987a122e74fb0fdf1bd6e864959fd3 upstream. The description of TX_VBOOST_LVL is wrong in register PHY_CTRL3 bit[31:29]. The updated description as below: 011: Corresponds to a launch amplitude of 0.844 V. 100: Corresponds to a launch amplitude of 1.008 V. 101: Corresponds to a launch amplitude of 1.156 V. This will fix the parsing function phy_tx_vboost_level_from_property() to return correct value.
