2022-11-10phy: renesas: Add Renesas Ethernet SERDES driver for R-Car S4-8Yoshihiro Shimoda1-0/+1
Add Renesas Ethernet SERDES driver for R-Car S4-8 (r8a779f0). The datasheet describes initialization procedure without any information about registers' name/bits. So, this is all black magic to initialize the hardware. Especially, all channels should be initialized at once.

2018-07-10phy: Renesas R-Car gen3 PCIe PHY driverSergei Shtylyov1-0/+1
This PHY is still mostly undocumented -- the only documented registers exist on R-Car V3H (R8A77980) SoC where this PHY stays in a powered-down state after a reset and thus we must power it up for PCIe to work...

2017-06-07phy: rcar-gen3-usb3: add support for R-Car Gen3 USB 3.0 PHYYoshihiro Shimoda1-0/+1
The USB 3.0 PHY modules of R-Car Gen3 SoCs have: - Spread spectrum clock (ssc). - Using USB 2.0 EXTAL clock instead of USB 3.0 clock. - Enabling VBUS detection for usb3.0 peripheral. So, this driver supports these features. Signed-off-by: Yoshihiro Shimoda <[email protected]> Signed-off-by: Kishon Vijay Abraham I <[email protected]>
2017-06-01phy: Group vendor specific phy driversVivek Gautam1-0/+2
Adding vendor specific directories in phy to group phy drivers under their respective vendor umbrella. Also updated the MAINTAINERS file to reflect the correct directory structure for phy drivers.
