8 bool "Enable Driver Model for Misc drivers"
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
17 bool "Altera Sysid support"
20 Select this to enable a sysid for Altera devices. Please find
21 details on the "Embedded Peripherals IP User Guide" of Altera.
24 bool "Enable crosec command"
27 Enable command-line access to the Chrome OS EC (Embedded
28 Controller). This provides the 'crosec' command which has
29 a number of sub-commands for performing EC tasks such as
30 updating its flash, accessing a small saved context area
31 and talking to the I2C bus behind the EC (if there is one).
34 bool "Enable Chrome OS EC"
36 Enable access to the Chrome OS EC. This is a separate
37 microcontroller typically available on a SPI bus on Chromebooks. It
38 provides access to the keyboard, some internal storage and may
39 control access to the battery and main PMIC depending on the
40 device. You can use the 'crosec' command to access it.
43 bool "Enable Chrome OS EC I2C driver"
46 Enable I2C access to the Chrome OS EC. This is used on older
47 ARM Chromebooks such as snow and spring before the standard bus
48 changed to SPI. The EC will accept commands across the I2C using
49 a special message protocol, and provide responses.
52 bool "Enable Chrome OS EC LPC driver"
55 Enable I2C access to the Chrome OS EC. This is used on x86
56 Chromebooks such as link and falco. The keyboard is provided
57 through a legacy port interface, so on x86 machines the main
58 function of the EC is power and thermal management.
60 config CROS_EC_SANDBOX
61 bool "Enable Chrome OS EC sandbox driver"
62 depends on CROS_EC && SANDBOX
64 Enable a sandbox emulation of the Chrome OS EC. This supports
65 keyboard (use the -l flag to enable the LCD), verified boot context,
66 EC flash read/write/erase support and a few other things. It is
67 enough to perform a Chrome OS verified boot on sandbox.
70 bool "Enable Chrome OS EC SPI driver"
73 Enable SPI access to the Chrome OS EC. This is used on newer
74 ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
75 provides a faster and more robust interface than I2C but the bugs
79 bool "Enable support for DS4510 CPU supervisor"
81 Enable support for the Maxim DS4510 CPU supervisor. It has an
82 integrated 64-byte EEPROM, four programmable non-volatile I/O pins
83 and a configurable timer for the supervisor function. The device is
87 bool "Enable FSL SEC_MON Driver"
89 Freescale Security Monitor block is responsible for monitoring
91 Security Monitor can be transitioned on any security failures,
92 like software violations or hardware security violations.
95 bool "Enable MXC OCOTP Driver"
97 If you say Y here, you will get support for the One Time
98 Programmable memory pages that are stored on the some
99 Freescale i.MX processors.
101 config NUVOTON_NCT6102D
102 bool "Enable Nuvoton NCT6102D Super I/O driver"
104 If you say Y here, you will get support for the Nuvoton
105 NCT6102D Super I/O driver. This can be used to enable or
106 disable the legacy UART, the watchdog or other devices
107 in the Nuvoton Super IO chips on X86 platforms.
110 bool "Enable power-sequencing drivers"
113 Power-sequencing drivers provide support for controlling power for
114 devices. They are typically referenced by a phandle from another
115 device. When the device is started up, its power sequence can be
119 bool "Enable power-sequencing drivers for SPL"
122 Power-sequencing drivers provide support for controlling power for
123 devices. They are typically referenced by a phandle from another
124 device. When the device is started up, its power sequence can be
128 bool "Enable PCA9551 LED driver"
130 Enable driver for PCA9551 LED controller. This controller
131 is connected via I2C. So I2C needs to be enabled.
133 config PCA9551_I2C_ADDR
134 hex "I2C address of PCA9551 LED controller"
135 depends on PCA9551_LED
138 The I2C address of the PCA9551 LED controller.
141 bool "Enable support for the Tegra CAR driver"
142 depends on TEGRA_NO_BPMP
144 The Tegra CAR (Clock and Reset Controller) is a HW module that
145 controls almost all clocks and resets in a Tegra SoC.
148 bool "Enable support for the Tegra186 BPMP driver"
151 The Tegra BPMP (Boot and Power Management Processor) is a separate
152 auxiliary CPU embedded into Tegra to perform power management work,
153 and controls related features such as clocks, resets, power domains,
154 PMIC I2C bus, etc. This driver provides the core low-level
155 communication path by which feature-specific drivers (such as clock)
156 can make requests to the BPMP. This driver is similar to an MFD
157 driver in the Linux kernel.
159 config WINBOND_W83627
160 bool "Enable Winbond Super I/O driver"
162 If you say Y here, you will get support for the Winbond
163 W83627 Super I/O driver. This can be used to enable the
164 legacy UART or other devices in the Winbond Super IO chips
170 Hidden option to enable QEMU fw_cfg interface. This will be selected by
171 either CONFIG_CMD_QFW or CONFIG_GENERATE_ACPI_TABLE.
174 bool "Enable driver for generic I2C-attached EEPROMs"
177 Enable a generic driver for EEPROMs attached via I2C.
