2019-03-06ec/lenovo/h8: Implement ACPI methods to set battery thresholdsAlexey Kharlamov
There are two known reverse-engineered ways to manage battery thresholds. This patch implements them and adds a way to enable them for different mainboards. Tested on W530 with 4.18.3-gentoo kernel and X220 with 4.20.11. Works fine with new Linux userspace API for controlling battery thresholds, available since 4.17. (/sys/class/power_supply/BAT0/charge_(start|stop)_threshold). The new API is supported by TLP (you might need to set NATACPI_ENABLE=1 in /etc/tlp.conf). tpacpi-bat works fine too.

2018-10-17mb/lenovo/*/acpi: Store the requested state wake state for bluetooth and WWANPatrick Rudolph
L520 and T420 should also use it - platforms are very similar to t420s and t530. Z61t is based on T60/X60, X131e is based on X230 so commit with Change-Id I13c08b8c6b1bf0f3deb25a464b26880d8469c005 should be applied as well. All four platforms are using ec/lenovo/h8 embedded controller.

2017-02-28mainboard/lenovo: Power off USB and mute audio before entering S3Nicola Corna
Currently, the USB ports are still powered during S3, so turning them off may reduce the power consumption. Note that, when the USB Always on feature is enabled, the USB ports are always powered, regardless of the USBP state. This patch also disables the audio, as it might consume some power or generate some noise. Both the USB power and the audio are reenabled by coreboot during the poweron.

Reorder drivers to fit src/drivers/[X]/[Y]/ scheme to make them pluggable. Also, fix up the following driver subdirectories by switching to the src/drivers/[X]/[Y]/ scheme as these are hard requirements for the main change: * drivers/intel * drivers/pc80 * drivers/dec Change-Id: I455d3089a317181d5b99bf658df759ec728a5f6b Signed-off-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Reviewed-on: https://review.coreboot.org/14047 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.com>
