Merge tag 'platform-drivers-x86-v4.21-1' of git://git.infradead.org/linux-platform-drivers-x86

Pull x86 platform driver updates from Andy Shevchenko:

 - 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
