The ChromeOS EC LPC and chardev drivers depend on CROS_EC_PROTO but MFD_CROS_EC select CROS_EC_PROTO instead. Mixing select and depends on is bad practice as it may lead to circular Kconfig dependencies. Since the platform devices that are matched with these drivers are registered by the ChromeOS EC mfd driver, they really depend on MFD_CROS_EC. And because this config option selects CROS_EC_PROTO, that dependency is met as well. So make the drivers to depend on MFD_CROS_EC instead of CROS_EC_PROTO.

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.
