7config MISC
8	bool "Enable Driver Model for Misc drivers"
9	depends on DM
10	help
11	  Enable driver model for miscellaneous devices. This class is
12	  used only for those do not fit other more general classes. A
13	  set of generic read, write and ioctl methods may be used to
14	  access the device.
15
16config ALTERA_SYSID
17	bool "Altera Sysid support"
18	depends on MISC
19	help
20	  Select this to enable a sysid for Altera devices. Please find
21	  details on the "Embedded Peripherals IP User Guide" of Altera.
22
23config ATSHA204A
24	bool "Support for Atmel ATSHA204A module"
25	depends on MISC
26	help
27	   Enable support for I2C connected Atmel's ATSHA204A
28	   CryptoAuthentication module found for example on the Turris Omnia
29	   board.

31config ROCKCHIP_EFUSE
32        bool "Rockchip e-fuse support"
33	depends on MISC
34	help
35	  Enable (read-only) access for the e-fuse block found in Rockchip
36	  SoCs: accesses can either be made using byte addressing and a length
37	  or through child-nodes that are generated based on the e-fuse map
38	  retrieved from the DTS.
39
40	  This driver currently supports the RK3399 only, but can easily be
41	  extended (by porting the read function from the Linux kernel sources)
42	  to support other recent Rockchip devices.
43
44config VEXPRESS_CONFIG
45	bool "Enable support for Arm Versatile Express config bus"
46	depends on MISC
47	help
48	  If you say Y here, you will get support for accessing the
49	  configuration bus on the Arm Versatile Express boards via
50	  a sysreg driver.
51
52config CMD_CROS_EC
53	bool "Enable crosec command"
54	depends on CROS_EC
55	help
56	  Enable command-line access to the Chrome OS EC (Embedded
57	  Controller). This provides the 'crosec' command which has
58	  a number of sub-commands for performing EC tasks such as
59	  updating its flash, accessing a small saved context area
60	  and talking to the I2C bus behind the EC (if there is one).
61
62config CROS_EC
63	bool "Enable Chrome OS EC"
64	help
65	  Enable access to the Chrome OS EC. This is a separate
66	  microcontroller typically available on a SPI bus on Chromebooks. It
67	  provides access to the keyboard, some internal storage and may
68	  control access to the battery and main PMIC depending on the
69	  device. You can use the 'crosec' command to access it.
70
71config CROS_EC_I2C
72	bool "Enable Chrome OS EC I2C driver"
73	depends on CROS_EC
74	help
75	  Enable I2C access to the Chrome OS EC. This is used on older
76	  ARM Chromebooks such as snow and spring before the standard bus
77	  changed to SPI. The EC will accept commands across the I2C using
78	  a special message protocol, and provide responses.
79
80config CROS_EC_LPC
81	bool "Enable Chrome OS EC LPC driver"
82	depends on CROS_EC
83	help
84	  Enable I2C access to the Chrome OS EC. This is used on x86
85	  Chromebooks such as link and falco. The keyboard is provided
86	  through a legacy port interface, so on x86 machines the main
87	  function of the EC is power and thermal management.
88
89config CROS_EC_SANDBOX
90	bool "Enable Chrome OS EC sandbox driver"
91	depends on CROS_EC && SANDBOX
92	help
93	  Enable a sandbox emulation of the Chrome OS EC. This supports
94	  keyboard (use the -l flag to enable the LCD), verified boot context,
95	  EC flash read/write/erase support and a few other things. It is
96	  enough to perform a Chrome OS verified boot on sandbox.
97
98config CROS_EC_SPI
99	bool "Enable Chrome OS EC SPI driver"
100	depends on CROS_EC
101	help
102	  Enable SPI access to the Chrome OS EC. This is used on newer
103	  ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
104	  provides a faster and more robust interface than I2C but the bugs
105	  are less interesting.
106
107config DS4510
108	bool "Enable support for DS4510 CPU supervisor"
109	help
110	  Enable support for the Maxim DS4510 CPU supervisor. It has an
111	  integrated 64-byte EEPROM, four programmable non-volatile I/O pins
112	  and a configurable timer for the supervisor function. The device is
113	  connected over I2C.
114
115config FSL_SEC_MON
116	bool "Enable FSL SEC_MON Driver"
117	help
118	  Freescale Security Monitor block is responsible for monitoring
119	  system states.
120	  Security Monitor can be transitioned on any security failures,
121	  like software violations or hardware security violations.
122
123config MXC_OCOTP
124	bool "Enable MXC OCOTP Driver"
125	help
126	  If you say Y here, you will get support for the One Time
127	  Programmable memory pages that are stored on the some
128	  Freescale i.MX processors.
129
130config NUVOTON_NCT6102D
131	bool "Enable Nuvoton NCT6102D Super I/O driver"
132	help
133	  If you say Y here, you will get support for the Nuvoton
134	  NCT6102D Super I/O driver. This can be used to enable or
135	  disable the legacy UART, the watchdog or other devices
136	  in the Nuvoton Super IO chips on X86 platforms.
137
138config PWRSEQ
139	bool "Enable power-sequencing drivers"
140	depends on DM
141	help
142	  Power-sequencing drivers provide support for controlling power for
143	  devices. They are typically referenced by a phandle from another
144	  device. When the device is started up, its power sequence can be
145	  initiated.
146
147config SPL_PWRSEQ
148	bool "Enable power-sequencing drivers for SPL"
149	depends on PWRSEQ
150	help
151	  Power-sequencing drivers provide support for controlling power for
152	  devices. They are typically referenced by a phandle from another
153	  device. When the device is started up, its power sequence can be

171	depends on ARCH_STM32MP && MISC
172	default y if CMD_FUSE
173	help
174	  If you say Y here, you will get support for the fuse API (OTP)
175	  for STM32MP architecture.
176	  This API is needed for CMD_FUSE.
177
178config STM32_RCC
179	bool "Enable RCC driver for the STM32 SoC's family"
180	depends on (STM32 || ARCH_STM32MP) && MISC
181	help
182	  Enable the STM32 RCC driver. The RCC block (Reset and Clock Control
183	  block) is responsible of the management of the clock and reset
184	  generation.
185	  This driver is similar to an MFD driver in the Linux kernel.
186
187config TEGRA_CAR
188	bool "Enable support for the Tegra CAR driver"
189	depends on TEGRA_NO_BPMP
190	help

192	  controls almost all clocks and resets in a Tegra SoC.
193
194config TEGRA186_BPMP
195	bool "Enable support for the Tegra186 BPMP driver"
196	depends on TEGRA186
197	help
198	  The Tegra BPMP (Boot and Power Management Processor) is a separate
199	  auxiliary CPU embedded into Tegra to perform power management work,
200	  and controls related features such as clocks, resets, power domains,
201	  PMIC I2C bus, etc. This driver provides the core low-level
202	  communication path by which feature-specific drivers (such as clock)
203	  can make requests to the BPMP. This driver is similar to an MFD
204	  driver in the Linux kernel.

213	help
214	  If you say Y here, you will get support for the Winbond
215	  W83627 Super I/O driver. This can be used to enable the
216	  legacy UART or other devices in the Winbond Super IO chips
217	  on X86 platforms.
218
219config QFW
220	bool
