2021-02-04platform/x86: ideapad-laptop: add "always on USB charging" control supportBarnabás Pőcze1-0/+9
Certain models have a so-called "always on USB charging" feature, which enables USB charging even when the computer is turned off or suspended, and which may be controlled/queried using the SALS/HALS ACPI methods. Expose this functionality via a new device attribute (usb_charging).

2017-05-15platform/x86: ideapad-laptop: Add sysfs interface for touchpad stateRitesh Raj Sarraf1-0/+8
Lenovo Yoga (many variants: Yoga, Yoga2 Pro, Yoga2 13, Yoga3 Pro, Yoga 3 14, etc) has multiple modles that are a hybrid laptop, working in laptop mode as well as tablet mode. Currently, there is no easy interface to determine the touchpad status, which in case of the Yoga family of machines, can also be useful to assume tablet mode status. Note: The ideapad-laptop driver does not provide a SW_TABLET_MODE either. For a detailed discussion on why we want either of the interfaces, please see: https://bugs.launchpad.net/onboard/+bug/1366421/comments/43 This patch adds a sysfs interface for read/write access under: /sys/bus/platform/devices/VPC2004\:00/touchpad_mode Signed-off-by: Ritesh Raj Sarraf <rrs@debian.org> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
2012-08-20ideapad: add Lenovo IdeaPad Z570 support (part 3)Maxim Mikityanskiy1-0/+11
The patch adds support for Lenovo IdeaPad Z570 laptop. It makes all special keys working, adds possibility to control fan like Windows does, controls Touchpad Disabled LED, toggles touchpad state via keyboard controller and corrects touchpad behavior on resume from suspend. It is new, modified version of patch. Now it does not depend on psmouse and does not need patching of input subsystem.
