platform-drivers-x86 for v4.21-1

The USB Power Delivery discrete components now can be enumerated by
 i2c-multi-instantiate driver via several resources under single ACPI
 device node (ACPI ID is INT3515).
 
 Touchscreen support is added for the Mediacom Flexbook Edge 11.
 
 Mellanox driver got fixed due to updates in their firmware.
 
 The power management stub driver for AtomISP v2 is fixed in order to support
 Intel Baytrail SoCs where same quirk is needed for S0ix to work.
 
 Special key handling has been fixed for Favorites hotkey on Thinkpad, and
 Screen LOCK on ASUS.
 
 Ideapad Yoga 2 13 has no HW rfkill switch, thus, driver has been updated
 to support this.
 
 Few cleanups related to debugfs have been made in Intel IPS and
 Intel PMC drivers. Besides that Intel PMC has been extended
 to show more detailed information about Latency Tolerance.
 
 The following is an automated git shortlog grouped by driver:
 
 ACPI / scan:
  -  Create platform device for INT3515 ACPI nodes
 
 Add the VLV ISP PCI ID to atomisp2_pm:
