   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.

  16 config 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.

  23 config CMD_CROS_EC
  24         bool "Enable crosec command"
  25         depends on CROS_EC
  26         help
  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).
  32
  33 config CROS_EC
  34         bool "Enable Chrome OS EC"
  35         help
  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.
  41
  42 config CROS_EC_I2C
  43         bool "Enable Chrome OS EC I2C driver"
  44         depends on CROS_EC
  45         help
  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.
  50
  51 config CROS_EC_LPC
  52         bool "Enable Chrome OS EC LPC driver"
  53         depends on CROS_EC
  54         help
  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.
  59
  60 config CROS_EC_SANDBOX
  61         bool "Enable Chrome OS EC sandbox driver"
  62         depends on CROS_EC && SANDBOX
  63         help
  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.
  68
  69 config CROS_EC_SPI
  70         bool "Enable Chrome OS EC SPI driver"
  71         depends on CROS_EC
  72         help
  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
  76           are less interesting.
  77
  78 config FSL_SEC_MON
  79         bool "Enable FSL SEC_MON Driver"
  80         help
  81           Freescale Security Monitor block is responsible for monitoring
  82           system states.
  83           Security Monitor can be transitioned on any security failures,
  84           like software violations or hardware security violations.
  85
  86 config MXC_OCOTP
  87         bool "Enable MXC OCOTP Driver"
  88         help
  89           If you say Y here, you will get support for the One Time
  90           Programmable memory pages that are stored on the some
  91           Freescale i.MX processors.
  92
  93 config PWRSEQ
  94         bool "Enable power-sequencing drivers"
  95         depends on DM
  96         help
  97           Power-sequencing drivers provide support for controlling power for
  98           devices. They are typically referenced by a phandle from another
  99           device. When the device is started up, its power sequence can be
 100           initiated.
 101
 102 config SPL_PWRSEQ
 103         bool "Enable power-sequencing drivers for SPL"
 104         depends on PWRSEQ
 105         help
 106           Power-sequencing drivers provide support for controlling power for
 107           devices. They are typically referenced by a phandle from another
 108           device. When the device is started up, its power sequence can be
 109           initiated.

 113         help
 114           Enable driver for PCA9551 LED controller. This controller
 115           is connected via I2C. So I2C needs to be enabled.
 116
 117 config PCA9551_I2C_ADDR
 118         hex "I2C address of PCA9551 LED controller"
 119         depends on PCA9551_LED
 120         default 0x60
 121         help
 122           The I2C address of the PCA9551 LED controller.

 124 config WINBOND_W83627
 125         bool "Enable Winbond Super I/O driver"
 126         help
 127           If you say Y here, you will get support for the Winbond
 128           W83627 Super I/O driver. This can be used to enable the
 129           legacy UART or other devices in the Winbond Super IO chips
 130           on X86 platforms.
 131
 132 config QFW
 133         bool
 134         help
 135           Hidden option to enable QEMU fw_cfg interface. This will be selected by
 136           either CONFIG_CMD_QFW or CONFIG_GENERATE_ACPI_TABLE.
 137
 138 config I2C_EEPROM
 139         bool "Enable driver for generic I2C-attached EEPROMs"
 140         depends on MISC
 141         help
 142           Enable a generic driver for EEPROMs attached via I2C.
