The Amlogic AXg SoCs embeds a MIPI D-PHY to communicate with DSI
panels, this adds the bindings.

This D-PHY depends on a separate analog PHY.

The Amlogic AXG MIPI + PCIe Analog PHY provides function for both PCIe and
MIPI DSI at the same time.

In order to configure the DSI PHY timings, a new "configure" PHY op is added to
permit dynamic (re)configuration of the PHY function.

Finally, the Linux MIPI D-PHY configuration helpers are imported to provide a standard
set of default D-PHY timings, timings struct and correct calculations.

Neil Armstrong (4):
  phy: dphy: Add configuration helpers
  generic-phy: add configure op
  phy: Add Amlogic AXG MIPI D-PHY driver
  phy: Add Amlogic AXG MIPI PCIe Analog PHY driver

Hi Simon, Tom,

Could you review patches 1 & 2 of this serie ?

Thanks,
Neil

Patches 1 and 2 look fine to me, FWIW.
