   9          Say Y here to get to see options for platform support for
  10          various Chromebooks and Chromeboxes. This option alone does
  11          not add any kernel code.

  13          If you say N, all options in this submenu will be skipped and disabled.

  21          This driver instantiates i2c and smbus devices such as
  22          light sensors and touchpads.
  23
  24          If you have a supported Chromebook, choose Y or M here.
  25          The module will be called chromeos_laptop.

  30        ---help---
  31          This module instantiates the persistent storage on x86 ChromeOS
  32          devices. It can be used to store away console logs and crash
  33          information across reboots.

  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.

  45          This driver adds support to talk with the ChromeOS EC from userspace.

  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.

  66        help
  67          If you say Y here, a variant LPC protocol for the Microchip EC
  68          will be used. Note that this variant is not backward compatible
  69          with non-Microchip ECs.
  70
  71          If you have a ChromeOS Embedded Controller Microchip EC variant
  72          choose Y here.

  83          This option enables support for the keyboard backlight LEDs on
  84          select Chrome OS systems.
  85
  86          To compile this driver as a module, choose M here: the
  87          module will be called cros_kbd_led_backlight.
