It can be used to store away console logs and crash 33 information across reboots. 34 35 The range of memory used is 0xf00000-0x1000000, traditionally 36 the memory used to back VGA controller memory. 37 38 If you have a supported Chromebook, choose Y or M here. 39 The module will be called chromeos_pstore. 40 41config CROS_EC_CHARDEV 42 tristate "Chrome OS Embedded Controller userspace device interface" 43 depends on MFD_CROS_EC 44 ---help--- 45 This driver adds support to talk with the ChromeOS EC from userspace. 46 47 If you have a supported Chromebook, choose Y or M here. 48 The module will be called cros_ec_dev. 49 50config CROS_EC_LPC 51 tristate "ChromeOS Embedded Controller (LPC)" 52 depends on MFD_CROS_EC && (X86 || COMPILE_TEST) 53 help 54 If you say Y here, you get support for talking to the ChromeOS EC 55 over an LPC bus. This uses a simple byte-level protocol with a 56 checksum. This is used for userspace access only. The kernel 57 typically has its own communication methods. 58 59 To compile this driver as a module, choose M here: the 60 module will be called cros_ec_lpc. 61 62config CROS_EC_PROTO 63 bool 64 help 65 ChromeOS EC communication protocol helpers. 66 67config CROS_KBD_LED_BACKLIGHT 68 tristate "Backlight LED support for Chrome OS keyboards" 69 depends on LEDS_CLASS && ACPI 70 help 71 This option enables support for the keyboard backlight LEDs on 72 select Chrome OS systems. 73 74 To compile this driver as a module, choose M here: the 75 module will be called cros_kbd_led_backlight. 76 77endif # CHROMEOS_PLATFORMS 78
