platform/chrome: Move cros-ec transport drivers to drivers/platform.

2018-07-03T19:40:06+00:00

There are some cros-ec transport drivers (I2C, SPI) living in MFD, while others (LPC) living in drivers/platform. The transport drivers are more platform specific. So, move the I2C and SPI transport drivers to the platform/chrome directory. The patch also removes the MFD_ prefix of their Kconfig symbols.

platform: chrome: Add input dependency for tablet switch driver

2018-05-29T05:51:27+00:00

Without CONFIG_INPUT, or with a modular input layer and built-in tablet driver, we get a link error: ERROR: "input_event" [drivers/platform/chrome/chromeos_tbmc.ko] undefined!

platform: chrome: Add Tablet Switch ACPI driver

2018-05-23T18:56:45+00:00

Add a kernel driver for GOOG0006, an ACPI driver reporting an event when the tablet switch status changes. On an ACPI based convertible chromebook check evtest display tablet mode switch changes: Available devices: .. /dev/input/event3: Tablet Mode Switch .. Testing ...

cros_ec: Move cros_ec_dev module to drivers/mfd

2017-12-15T10:46:06+00:00

The cros_ec_dev module is responsible for registering the MFD devices attached to the ChromeOS EC. This patch moves this module to drivers/mfd so calls to mfd_add_devices() are not done from outside the MFD subtree anymore.

cros_ec: Split cros_ec_devs module

2017-12-15T10:45:11+00:00

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.

platform/chrome: Make depends on MFD_CROS_EC instead CROS_EC_PROTO

2015-10-07T21:34:26+00:00

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.
