[PATCH 2/4] dt-bindings: phy: Add PCIe PHY support for ExynosAutov920 SoC

[Sanghoon Bae]

> > Since the Exynosautov920 SoC uses the Samsung PCIe PHY, add support

> > The Exynosautov920 SoC includes two PHY instances: one for a 4-lane
> > PHY and another for a 2-lane PHY. Each PHY can be used by separate

I will describe about the Exynosautov920 SoC PCIe hardware.

> > PCIe lane number is used to distinguish each PHY instance.
> > This is required since two PHY instances on ExynosAutov920 is not

> > On PHY driver code, need to check each instance and different settings.

> Describe hardware, not driver.
I will describe about the Exynosautov920 SoC PCIe hardware.
