platform/x86: thinkpad_acpi: Fix warning about deprecated hwmon_device_register

2017-08-18T22:57:24+00:00

Use hwmon_device_register_with_groups instead of deprecated
hwmon_device_register and fix a dmesg warning.

This patch however changes the userspace API.
hwmon_device_register_with_groups takes `hwmon' name as an argument and
creates a name file in the `hwmon' device, not in the `platform_device'.
This allows us to remove custom `name' device attribute, but in order to
make lm-sensors happy we also have to move fans and thermal attributes
to the `hwmon' device.

Even though this patch changes userspace API, it's still compatible with
the lm-sensors. Starting with lm-sensors 3.0 (circa 2007), it looks at
both hwmon and the backing device for the name and other attributes.

platform/x86: thinkpad_acpi: Add support for X1 Yoga (2016) Tablet Mode

2016-12-13T17:29:06+00:00

For whatever reason, the X1 Yoga doesn't support the normal method of
querying for tablet mode. Instead of providing the MHKG method under the
hotkey handle, we're instead given the CMMD method under the EC handle.
Values on this handle are either 0x1, laptop mode, or 0x6, tablet mode.

mode. This could be used by desktop environments to change the keyboard
mode depending on the application focused, as the Windows application
does.

Change the Documentation makefiles from obj-m to subdir-y
to avoid generating unnecessary built-in.o files since nothing
