menu "Multifunction device drivers"
config MISC
bool "Enable Driver Model for Misc drivers"
depends on DM
help
Enable driver model for miscellaneous devices. This class is
used only for those do not fit other more general classes. A
set of generic read, write and ioctl methods may be used to
access the device.
config ALTERA_SYSID
bool "Altera Sysid support"
depends on MISC
help
Select this to enable a sysid for Altera devices. Please find
details on the "Embedded Peripherals IP User Guide" of Altera.
config ATSHA204A
bool "Support for Atmel ATSHA204A module"
depends on MISC
help
Enable support for I2C connected Atmel's ATSHA204A
CryptoAuthentication module found for example on the Turris Omnia
board.
config ROCKCHIP_EFUSE
bool "Rockchip e-fuse support"
depends on MISC
help
Enable (read-only) access for the e-fuse block found in Rockchip
SoCs: accesses can either be made using byte addressing and a length
or through child-nodes that are generated based on the e-fuse map
retrieved from the DTS.
This driver currently supports the RK3399 only, but can easily be
extended (by porting the read function from the Linux kernel sources)
to support other recent Rockchip devices.
config CMD_CROS_EC
bool "Enable crosec command"
depends on CROS_EC
help
Enable command-line access to the Chrome OS EC (Embedded
Controller). This provides the 'crosec' command which has
a number of sub-commands for performing EC tasks such as
updating its flash, accessing a small saved context area
and talking to the I2C bus behind the EC (if there is one).
config CROS_EC
bool "Enable Chrome OS EC"
help
Enable access to the Chrome OS EC. This is a separate
microcontroller typically available on a SPI bus on Chromebooks. It
provides access to the keyboard, some internal storage and may
control access to the battery and main PMIC depending on the
device. You can use the 'crosec' command to access it.
config CROS_EC_I2C
bool "Enable Chrome OS EC I2C driver"
depends on CROS_EC
help
Enable I2C access to the Chrome OS EC. This is used on older
ARM Chromebooks such as snow and spring before the standard bus
changed to SPI. The EC will accept commands across the I2C using
a special message protocol, and provide responses.
config CROS_EC_LPC
bool "Enable Chrome OS EC LPC driver"
depends on CROS_EC
help
Enable I2C access to the Chrome OS EC. This is used on x86
Chromebooks such as link and falco. The keyboard is provided
through a legacy port interface, so on x86 machines the main
function of the EC is power and thermal management.
config CROS_EC_SANDBOX
bool "Enable Chrome OS EC sandbox driver"
depends on CROS_EC && SANDBOX
help
Enable a sandbox emulation of the Chrome OS EC. This supports
keyboard (use the -l flag to enable the LCD), verified boot context,
EC flash read/write/erase support and a few other things. It is
enough to perform a Chrome OS verified boot on sandbox.
config CROS_EC_SPI
bool "Enable Chrome OS EC SPI driver"
depends on CROS_EC
help
Enable SPI access to the Chrome OS EC. This is used on newer
ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
provides a faster and more robust interface than I2C but the bugs
are less interesting.
config DS4510
bool "Enable support for DS4510 CPU supervisor"
help
Enable support for the Maxim DS4510 CPU supervisor. It has an
integrated 64-byte EEPROM, four programmable non-volatile I/O pins
and a configurable timer for the supervisor function. The device is
connected over I2C.
config FSL_SEC_MON
bool "Enable FSL SEC_MON Driver"
help
Freescale Security Monitor block is responsible for monitoring
system states.
Security Monitor can be transitioned on any security failures,
like software violations or hardware security violations.
config MXC_OCOTP
bool "Enable MXC OCOTP Driver"
help
If you say Y here, you will get support for the One Time
Programmable memory pages that are stored on the some
Freescale i.MX processors.
config NUVOTON_NCT6102D
bool "Enable Nuvoton NCT6102D Super I/O driver"
help
If you say Y here, you will get support for the Nuvoton
NCT6102D Super I/O driver. This can be used to enable or
disable the legacy UART, the watchdog or other devices
in the Nuvoton Super IO chips on X86 platforms.
config PWRSEQ
bool "Enable power-sequencing drivers"
depends on DM
help
Power-sequencing drivers provide support for controlling power for
devices. They are typically referenced by a phandle from another
device. When the device is started up, its power sequence can be
initiated.
config SPL_PWRSEQ
bool "Enable power-sequencing drivers for SPL"
depends on PWRSEQ
help
Power-sequencing drivers provide support for controlling power for
devices. They are typically referenced by a phandle from another
device. When the device is started up, its power sequence can be
initiated.
config PCA9551_LED
bool "Enable PCA9551 LED driver"
help
Enable driver for PCA9551 LED controller. This controller
is connected via I2C. So I2C needs to be enabled.
config PCA9551_I2C_ADDR
hex "I2C address of PCA9551 LED controller"
depends on PCA9551_LED
default 0x60
help
The I2C address of the PCA9551 LED controller.
config TEGRA_CAR
bool "Enable support for the Tegra CAR driver"
depends on TEGRA_NO_BPMP
help
The Tegra CAR (Clock and Reset Controller) is a HW module that
controls almost all clocks and resets in a Tegra SoC.
config TEGRA186_BPMP
bool "Enable support for the Tegra186 BPMP driver"
depends on TEGRA186
help
The Tegra BPMP (Boot and Power Management Processor) is a separate
auxiliary CPU embedded into Tegra to perform power management work,
and controls related features such as clocks, resets, power domains,
PMIC I2C bus, etc. This driver provides the core low-level
communication path by which feature-specific drivers (such as clock)
can make requests to the BPMP. This driver is similar to an MFD
driver in the Linux kernel.
config WINBOND_W83627
bool "Enable Winbond Super I/O driver"
help
If you say Y here, you will get support for the Winbond
W83627 Super I/O driver. This can be used to enable the
legacy UART or other devices in the Winbond Super IO chips
on X86 platforms.
config QFW
bool
help
Hidden option to enable QEMU fw_cfg interface. This will be selected by
either CONFIG_CMD_QFW or CONFIG_GENERATE_ACPI_TABLE.
config I2C_EEPROM
bool "Enable driver for generic I2C-attached EEPROMs"
depends on MISC
help
Enable a generic driver for EEPROMs attached via I2C.
