This PHY is still mostly undocumented -- the only documented registers exist on R-Car V3H (R8A77980) SoC. Add the corresponding device tree bindings.
Signed-off-by: Sergei Shtylyov <[email protected]> --- Changes in version 2: - split from the big driver/bindings patch; - got rid of the generic R-Car gen3 "compatible" prop value.
