[PATCH v5 0/2] Add new PHY APIs to framework to get/set PHY attributes

From: Swapnil Jakhade
Date: Mon Aug 24 2020 - 14:29:02 EST


This patch series adds a new pair of PHY APIs that can be used to get/set
all the PHY attributes. It also adds a new PHY attribute max_link_rate.

It includes following patches:

1. v5-0001-phy-Add-new-PHY-attribute-max_link_rate-and-APIs-.patch
This patch adds max_link_rate as a new PHY attribute along with a pair of
APIs that allow using the generic PHY subsystem to get/set PHY attributes
supported by the PHY.

2. v5-0002-phy-cadence-torrent-Use-kernel-PHY-API-to-set-PHY.patch
This patch uses PHY API phy_set_attrs() to set corresponding PHY properties
in Cadence Torrent PHY driver. This will enable drivers using this PHY to
read these properties using PHY framework.

The phy_get_attrs() API will be used in the DRM bridge driver [1] which is
in the process of upstreaming.
