2 # Platform support for Chrome OS hardware (Chromebooks and Chromeboxes)
5 menuconfig CHROME_PLATFORMS
6 bool "Platform support for Chrome hardware"
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.
17 config CHROMEOS_LAPTOP
18 tristate "Chrome OS Laptop"
19 depends on I2C && DMI && X86
21 This driver instantiates i2c and smbus devices such as
22 light sensors and touchpads.
24 If you have a supported Chromebook, choose Y or M here.
25 The module will be called chromeos_laptop.
27 config CHROMEOS_PSTORE
28 tristate "Chrome OS pstore support"
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.
38 If you have a supported Chromebook, choose Y or M here.
39 The module will be called chromeos_pstore.
41 config CROS_EC_CHARDEV
42 tristate "Chrome OS Embedded Controller userspace device interface"
43 depends on MFD_CROS_EC
45 This driver adds support to talk with the ChromeOS EC from userspace.
47 If you have a supported Chromebook, choose Y or M here.
48 The module will be called cros_ec_dev.
51 tristate "ChromeOS Embedded Controller (LPC)"
52 depends on MFD_CROS_EC && (X86 || COMPILE_TEST)
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.
59 To compile this driver as a module, choose M here: the
60 module will be called cros_ec_lpc.
