Thierry Escande ea01a31b90 cros_ec: Split cros_ec_devs module
This patch splits the cros_ec_devs module in two parts with a
cros_ec_dev module responsible for handling MFD devices registration and
a cros_ec_ctl module responsible for handling the various user-space
interfaces.

For consistency purpose, the driver name for the cros_ec_dev module is
now cros-ec-dev instead of cros-ec-ctl.

In the next commit, the new cros_ec_dev module will be moved to the MFD
subtree so mfd_add_devices() calls are not done from outside MFD.

menuconfig CHROME_PLATFORMS
bool "Platform support for Chrome hardware"
depends on X86 || ARM || ARM64 || COMPILE_TEST
---help---
Say Y here to get to see options for platform support for
various Chromebooks and Chromeboxes. This option alone does
not add any kernel code.
If you say N, all options in this submenu will be skipped and disabled.
if CHROME_PLATFORMS
config CHROMEOS_LAPTOP
tristate "Chrome OS Laptop"
depends on I2C && DMI && X86
---help---
This driver instantiates i2c and smbus devices such as
light sensors and touchpads.
If you have a supported Chromebook, choose Y or M here.
The module will be called chromeos_laptop.
config CHROMEOS_PSTORE
tristate "Chrome OS pstore support"
depends on X86
---help---
This module instantiates the persistent storage on x86 ChromeOS
devices. It can be used to store away console logs and crash
information across reboots.
The range of memory used is 0xf00000-0x1000000, traditionally
the memory used to back VGA controller memory.
If you have a supported Chromebook, choose Y or M here.
The module will be called chromeos_pstore.
config CROS_EC_CHARDEV
tristate "Chrome OS Embedded Controller userspace device interface"
depends on MFD_CROS_EC
select CROS_EC_CTL
---help---
This driver adds support to talk with the ChromeOS EC from userspace.
If you have a supported Chromebook, choose Y or M here.
The module will be called cros_ec_dev.

tristate "ChromeOS Embedded Controller (LPC)"

help
If you say Y here, you get support for talking to the ChromeOS EC
over an LPC bus. This uses a simple byte-level protocol with a
checksum. This is used for userspace access only. The kernel
typically has its own communication methods.
To compile this driver as a module, choose M here: the
module will be called cros_ec_lpc.

bool "ChromeOS Embedded Controller LPC Microchip EC (MEC) variant"
depends on CROS_EC_LPC
default n
help
If you say Y here, a variant LPC protocol for the Microchip EC
will be used. Note that this variant is not backward compatible
with non-Microchip ECs.
If you have a ChromeOS Embedded Controller Microchip EC variant
choose Y here.

This option enables support for the keyboard backlight LEDs on
