Add a Sierra PHY driver with PCIe and USB support. The PHY has multiple lanes, which can be configured into groups, and a generic PHY device is created for each group. There are two resets controlling the overall PHY block, one to enable the APB interface for programming registers, and another to enable the PHY itself. Additionally there are resets for each PHY lane. The PHY can be configured in hardware to read register settings from ROM, or they can be written by the driver. The sequence of operation on startup is to enable the APB bus, write the PHY registers (if required) for each lane group, and then enable the PHY. Each group of lanes can then be individually controlled using the power_on()/ power_off() function for that generic PHY Signed-off-by: Alan Douglas <adouglas@cadence.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> |
