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 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 33config 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 42config 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 51config 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 60config 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 69config 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 78config DS4510 79 bool "Enable support for DS4510 CPU supervisor" 80 help 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 84 connected over I2C. 85 86config FSL_SEC_MON 87 bool "Enable FSL SEC_MON Driver" 88 help 89 Freescale Security Monitor block is responsible for monitoring 90 system states. 91 Security Monitor can be transitioned on any security failures, 92 like software violations or hardware security violations. 93 94config MXC_OCOTP 95 bool "Enable MXC OCOTP Driver" 96 help 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. 100 101config NUVOTON_NCT6102D 102 bool "Enable Nuvoton NCT6102D Super I/O driver" 103 help 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. 108 109config PWRSEQ 110 bool "Enable power-sequencing drivers" 111 depends on DM 112 help 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 116 initiated. 117 118config SPL_PWRSEQ 119 bool "Enable power-sequencing drivers for SPL" 120 depends on PWRSEQ 121 help 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 125 initiated. 126 127config PCA9551_LED 128 bool "Enable PCA9551 LED driver" 129 help 130 Enable driver for PCA9551 LED controller. This controller 131 is connected via I2C. So I2C needs to be enabled. 132 133config PCA9551_I2C_ADDR 134 hex "I2C address of PCA9551 LED controller" 135 depends on PCA9551_LED 136 default 0x60 137 help 138 The I2C address of the PCA9551 LED controller. 139 140config TEGRA_CAR 141 bool "Enable support for the Tegra CAR driver" 142 depends on TEGRA_NO_BPMP 143 help 144 The Tegra CAR (Clock and Reset Controller) is a HW module that 145 controls almost all clocks and resets in a Tegra SoC. 146 147config TEGRA186_BPMP 148 bool "Enable support for the Tegra186 BPMP driver" 149 depends on TEGRA186 150 help 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. 158 159config WINBOND_W83627 160 bool "Enable Winbond Super I/O driver" 161 help 162 If you say Y here, you will get support for the Winbond 163 W83627 Super I/O driver.
