platform-drivers-x86 for v4.19-1 

The driver for Silead touchscreen configurations has been renamed
 from silead_dmi to touchscreen_dmi since it starts supporting other
 touchscreens which require some DMI quirks. At the same release cycle
 it gets expanded to cover cases for Chuwi Vi10, ONDA V891W,
 Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets.
 
 Another bunch of changes is related to Mellanox platform code to allow
 user space to communicate with Mellanox for system control and
 monitoring purposes. The driver notifies user on hotplug device signal
 receiving.
 
 ASUS WMI drivers recognize lid flip action on UX360, and correctly
 toggles airplane mode LED. In addition the keyboard backlight toggle
 gets support.
 
 ThinkPad ACPI driver enables support for calculator key (on at least P52).
 It also has been fixed to support three characters model designators,
 which are used for modern laptops. Earlier the battery, marked as BAT1,
 on ThinkPad laptops has not been configured properly, which is fixed.
 On the opposite the multi-battery configurations now probed correctly.
 
 Dell SMBIOS driver starts working on some Dell servers which do not
 support token interface. The regression with backlight detection has
 also been fixed. In order to support dock mode on some laptops,
 Intel virtual button driver has been fixed. The last but not least
 is the fix to Intel HID driver due to changes in Dell systems that
 prevented to use power button.

If both are written 1 - power supplies main power domain will
go down.
When pwr_down is written 1, system's main power domain will go
down.
