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. v1-0001-phy-Add-max_link_rate-as-a-PHY-attribute-along-wi.patch This patch adds max_link_rate as a PHY attribute along with a pair of APIs that allow the generic PHY subsystem to provide information on the maximum value of link rate supported by the PHY. The PHY provider driver may use phy_set_max_link_rate() to set the value that PHY supports. The controller driver may then use phy_get_max_link_rate() to fetch the PHY link rate in order to properly configure the controller. 2. v1-0002-phy-phy-cadence-torrent-Use-PHY-kernel-APIs-to-se.patch This patch uses kernel PHY APIs phy_set_bus_width() and phy_set_max_link_rate() 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 get API's will be used in the Cadence MHDP DRM bridge driver [1] which is under review for upstreaming.
