4config PHY
5	bool "PHY Core"
6	depends on DM
7	help
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.

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

26	  This framework is designed to provide a generic interface for PHY
27	  devices. PHY devices are dedicated hardware that handle the physical
28	  layer of the protocols (https://en.wikipedia.org/wiki/OSI_model).
29	  PHYs are commonly used for high speed interfaces such as Serial-ATA
30	  or PCI express.
31	  The API provides functions to initialize/deinitialize the
32	  PHY, power on/off the PHY, and reset the PHY. It's meant to be as
33	  compatible as possible with the equivalent framework found in the
34	  linux kernel.

36config 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
44config 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
53config 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.
61
62config 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
71config SPL_PIPE3_PHY
72	bool "Support omap's PIPE3 PHY in SPL"
73	depends on SPL_PHY && ARCH_OMAP2PLUS
74	help
75	  Support for the omap PIPE3 phy for sata in SPL
76
77	  This PHY is found on omap devices supporting SATA such as dra7, am57x
78	  and omap5
79
80config 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.
