From: Xu Yang xu.yang_2@nxp.com
commit 5b3a91b207c00a8d27f75ce8aaa9860844da72c8 upstream.
The ticket TKT0676370 shows the description of TX_VBOOST_LVL is wrong in register PHY_CTRL3 bit[31:29].
011: Corresponds to a launch amplitude of 1.12 V. 010: Corresponds to a launch amplitude of 1.04 V. 000: Corresponds to a launch amplitude of 0.88 V.
After updated:
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 correct it accordingly.
