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.
