[PATCH 6.12 23/24] dt-bindings: phy: imx8mq-usb: fix fsl,phy-tx-vboost-level-microvolt property

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

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.
