Hi,

Starting from Intel Cannon Lake PCH the NO_REBOOT bit which is required by
the iTCO driver was moved from private register space to be part of the
TCO1_CNT register. This series introduces a new iTCO version (6) that gets
set for Cannon Lake, Cedar Fork, Comet Lake, Elkhart Lake and Ice Lake
which are affected by this move.

The previous version of the series can be found here:

  https://lore.kernel.org/linux-watchdog/20190809124553.67012-1-mika.westerberg@linux.intel.com/

Changes from v1:

  * Include <linux/bits.h> for BIT()
  * Re-organize code so that v4 support is before v6
  * Move check for acpi_has_watchdog() to i801_add_tco()
  * Added tags from Jean and Guenter.
