8 	  PHY support.
9 
10 	  This framework is designed to provide a generic interface for PHY
11 	  devices. PHY devices are dedicated hardware that handle the physical
12 	  layer of the protocols in the OSI model.
13 	  PHYs are commonly used for high speed interfaces such as Serial-ATA
14 	  or PCI express.
15 	  The API provides functions to initialize/deinitialize the
16 	  PHY, power on/off the PHY, and reset the PHY. It's meant to be as
17 	  compatible as possible with the equivalent framework found in the
18 	  linux kernel.

20 config SPL_PHY
21 	bool "PHY Core in SPL"
22 	depends on DM
23 	help
24 	  PHY support in SPL.

36 config PHY_SANDBOX
37 	bool "Sandbox PHY support"
38 	depends on SANDBOX
39 	depends on PHY
40 	help
41 	  This select a dummy sandbox PHY driver. It used only to implement
42 	  the unit tests for the phy framework
43 
44 config NOP_PHY
45 	bool "NOP PHY driver"
46 	depends on PHY
47 	help
48 	  Support for a no-op PHY driver (stubbed PHY driver).
49 
50 	  This is useful when a driver uses the PHY framework but no real PHY
51 	  hardware exists.
52 
53 config SPL_NOP_PHY
54 	bool "NOP PHY driver in SPL"
55 	depends on SPL_PHY
56 	help
57 	  Support for a no-op PHY driver (stubbed PHY driver) in the SPL.
58 
59 	  This is useful when a driver uses the PHY framework but no real PHY
60 	  hardware exists.

62 config PIPE3_PHY
63 	bool "Support omap's PIPE3 PHY"
64 	depends on PHY && ARCH_OMAP2PLUS
65 	help
66 	  Support for the omap PIPE3 phy for sata
67 
68 	  This PHY is found on omap devices supporting SATA such as dra7, am57x
69 	  and omap5
70

80 config STI_USB_PHY
81 	bool "STMicroelectronics USB2 picoPHY driver for STiH407 family"
82 	depends on PHY && ARCH_STI
83 	help
84 	  This is the generic phy driver for the picoPHY ports
85 	  used by USB2 and USB3 Host controllers available on
86 	  STiH407 SoC families.
