Subject: [PATCH v6 0/2] PHY: Add new PHY attribute max_link_rate

This patch series adds a new PHY attribute max_link_rate.
It also updates Cadence Torrent PHY driver to set attributes bus_width,
max_link_rate and mode for DisplayPort.

It includes following patches:

1. 0001-phy-Add-new-PHY-attribute-max_link_rate.patch
This patch adds max_link_rate as a new PHY attribute.

2. 0002-phy-cadence-torrent-Set-Torrent-PHY-attributes.patch
This patch sets PHY attributes in Cadence Torrent PHY driver. This will
enable drivers using this PHY to read these properties.

These attributes will be used in the Cadence MHDP DRM bridge driver [1]
which is in the process of upstreaming.
