platform: add chrome platform directory It makes sense to split out the Chromebook/Chromebox hardware platform drivers to a separate subdirectory, since some of it will be shared between ARM and x86. This moves over the existing chromeos_laptop driver without making any other changes, and adds appropriate Kconfig entries for the new directory. It also adds a MAINTAINERS entry for the new subdir.

platform/chrome: Add pstore platform_device Add the ramoops pstore device so that we get logs of panics across reboots. Signed-off-by: Olof Johansson <olof@lixom.net>

platform/chrome: Support reading/writing the vboot context Some EC implementations include a small nvram space used to store verified boot context data. This patch offers a way to expose this data to userspace.

platform/chrome: Create sysfs attributes for the ChromeOS EC This adds the first few sysfs attributes for the Chrome OS EC. These controls are made available under /sys/devices/virtual/chromeos/cros_ec flashinfo - display current flash info reboot - tell the EC to reboot in various ways version - information about the EC software and hardware Future changes will build on this to add additional controls. From a root shell, you should be able to do things like this: cd /sys/devices/virtual/chromeos/cros_ec cat flashinfo cat version echo rw > reboot cat version echo ro > reboot cat version echo rw > reboot cat version echo cold > reboot That last command will reboot the AP too.

obj-$(CONFIG_CROS_EC_CHARDEV) += cros_ec_devs.o
platform/chrome: Add cros_ec_lpc driver for x86 devices Chromebooks have an Embedded Controller (EC) that is used to implement various functions such as keyboard, power and battery. The AP can communicate with the EC through different bus types such as I2C, SPI or LPC. The cros_ec mfd driver is then composed of a core driver that register the sub-devices as mfd cells and provide a high level communication interface that is used by the rest of the kernel and bus specific interfaces modules. Each connection method then has its own driver, which register with the EC driver interface-agnostic interface. Currently, there are drivers to communicate with the EC over I2C and SPI and this driver adds support for LPC.

mfd: cros_ec: Move protocol helpers out of the MFD driver The MFD driver should only have the logic to instantiate its child devices and setup any shared resources that will be used by the subdevices drivers. The cros_ec MFD is more complex than expected since it also has helpers to communicate with the EC. So the driver will only get more bigger as other protocols are supported in the future. So move the communication protocol helpers to its own driver as drivers/platform/chrome/cros_ec_proto.c.
