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 ASPEED_AHBC
17	bool "Aspeed AHBC support"
18	depends on ARCH_ASPEED
19	help

49config ROCKCHIP_EFUSE
50        bool "Rockchip e-fuse support"
51	depends on MISC
52	help
53	  Enable (read-only) access for the e-fuse block found in Rockchip
54	  SoCs: accesses can either be made using byte addressing and a length
55	  or through child-nodes that are generated based on the e-fuse map
56	  retrieved from the DTS.
57
58	  This driver currently supports the RK3399 only, but can easily be
59	  extended (by porting the read function from the Linux kernel sources)
60	  to support other recent Rockchip devices.
61
62config VEXPRESS_CONFIG
63	bool "Enable support for Arm Versatile Express config bus"
64	depends on MISC
65	help
66	  If you say Y here, you will get support for accessing the

70config CMD_CROS_EC
71	bool "Enable crosec command"
72	depends on CROS_EC
73	help
74	  Enable command-line access to the Chrome OS EC (Embedded
75	  Controller). This provides the 'crosec' command which has
76	  a number of sub-commands for performing EC tasks such as
77	  updating its flash, accessing a small saved context area
78	  and talking to the I2C bus behind the EC (if there is one).
79
80config CROS_EC
81	bool "Enable Chrome OS EC"
82	help
83	  Enable access to the Chrome OS EC. This is a separate
84	  microcontroller typically available on a SPI bus on Chromebooks. It
85	  provides access to the keyboard, some internal storage and may
86	  control access to the battery and main PMIC depending on the
87	  device. You can use the 'crosec' command to access it.
88
89config CROS_EC_I2C
90	bool "Enable Chrome OS EC I2C driver"
91	depends on CROS_EC
92	help
93	  Enable I2C access to the Chrome OS EC. This is used on older
94	  ARM Chromebooks such as snow and spring before the standard bus
95	  changed to SPI. The EC will accept commands across the I2C using
96	  a special message protocol, and provide responses.
97
98config CROS_EC_LPC
99	bool "Enable Chrome OS EC LPC driver"
100	depends on CROS_EC
101	help
102	  Enable I2C access to the Chrome OS EC. This is used on x86
103	  Chromebooks such as link and falco. The keyboard is provided
104	  through a legacy port interface, so on x86 machines the main
105	  function of the EC is power and thermal management.
106
107config CROS_EC_SANDBOX
108	bool "Enable Chrome OS EC sandbox driver"
109	depends on CROS_EC && SANDBOX
110	help
111	  Enable a sandbox emulation of the Chrome OS EC. This supports
112	  keyboard (use the -l flag to enable the LCD), verified boot context,
113	  EC flash read/write/erase support and a few other things. It is
114	  enough to perform a Chrome OS verified boot on sandbox.
115
116config CROS_EC_SPI
117	bool "Enable Chrome OS EC SPI driver"
118	depends on CROS_EC
119	help
120	  Enable SPI access to the Chrome OS EC. This is used on newer
121	  ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
122	  provides a faster and more robust interface than I2C but the bugs
123	  are less interesting.
124
125config DS4510
126	bool "Enable support for DS4510 CPU supervisor"
127	help
128	  Enable support for the Maxim DS4510 CPU supervisor. It has an
129	  integrated 64-byte EEPROM, four programmable non-volatile I/O pins
130	  and a configurable timer for the supervisor function. The device is
131	  connected over I2C.
132
133config FSL_SEC_MON
134	bool "Enable FSL SEC_MON Driver"
135	help
136	  Freescale Security Monitor block is responsible for monitoring
137	  system states.

156	help
157	  If you say Y here, you will get support for the Nuvoton
158	  NCT6102D Super I/O driver. This can be used to enable or
159	  disable the legacy UART, the watchdog or other devices
160	  in the Nuvoton Super IO chips on X86 platforms.
161
162config PWRSEQ
163	bool "Enable power-sequencing drivers"
164	depends on DM
165	help
166	  Power-sequencing drivers provide support for controlling power for
167	  devices. They are typically referenced by a phandle from another
168	  device. When the device is started up, its power sequence can be

204	depends on (STM32 || ARCH_STM32MP) && MISC
205	help
206	  Enable the STM32 RCC driver. The RCC block (Reset and Clock Control
207	  block) is responsible of the management of the clock and reset
208	  generation.

219	bool "Enable support for the Tegra186 BPMP driver"
220	depends on TEGRA186
221	help
222	  The Tegra BPMP (Boot and Power Management Processor) is a separate
223	  auxiliary CPU embedded into Tegra to perform power management work,
224	  and controls related features such as clocks, resets, power domains,
225	  PMIC I2C bus, etc. This driver provides the core low-level
226	  communication path by which feature-specific drivers (such as clock)
227	  can make requests to the BPMP. This driver is similar to an MFD
228	  driver in the Linux kernel.
