[PATCH v2 0/9] Describe PCIe/USB3.0 clock generator on R-Car Gen3

[Marek Vasut]

Describe the 9FGV0841 PCIe and USB3.0 clock generator present on
various R-Car Gen3 boards. The clock generator supplies 100 MHz
differential clock for PCIe ports, USB 3.0 PHY and SATA.

The series effectively has three parts. The first part is description
of PCIe root ports on R-Car Gen3 SoCs where applicable, in this case
that is H3/M3W/M3N/E3. The root port is used with PCIe port power
control to also control the PCIe port clock. This is needed on Gen3
boards, because they often use separate clock output from the PCIe
clock generator 9FGV0841 to supply clock to the controller and to the
PCIe port.

The second part is a single patch, which fills in the missing USB 3.0
PHY on R-Car E3 as usb-nop-xceiv, thus aligning the R-Car E3 USB 3.0
support with the rest of the Gen3 SoCs.

The third part is enablement of the 9FGV0841 PCIe clock controller on
the R-Car Salvator-X/XS, ULCB and Ebisu boards. The boards use the
PCIe clock controller outputs in a slightly different manner, all use
the outputs to supply PCIe controllers and slots, as well as USB 3.0
SuperSpeed PHY. The ULCB board also uses the 9FGV0841 to supply SATA
IP, but this is not yet described in DT, therefore it is also not part
of this series.
