> Subject: [PATCH v2 0/2] Add support to get/set PHY attributes using PHY
> framework
>
> This patch series adds support to use kernel PHY subsystem APIs to get/set
> PHY attributes like number of lanes and maximum link rate.
>
> It includes following patches:
>
> 1. v2-0001-phy-Add-max_link_rate-as-a-PHY-attribute-and-APIs.patch
> This patch adds max_link_rate as a PHY attribute along with a pair of APIs
> that allow the generic PHY subsystem to get/set PHY attributes supported by
> the PHY.
> The PHY provider driver may use phy_set_attrs() API to set the values that
> PHY supports.
> The controller driver may then use phy_get_attrs() API to fetch the PHY
> attributes in order to properly configure the controller.
>
> 2. v2-0002-phy-phy-cadence-torrent-Use-kernel-PHY-API-to-set.patch
> This patch uses kernel 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
> process of upstreaming.
