Subject: [PATCH 0/5] iTCO_wdt: Add support for Intel Sunrisepoint

From: Matt Fleming <matt.fleming@...el.com>

Starting with Intel Sunrisepoint (Skylake PCH) the TCO watchdog device
is now on the SMBUS, whereas for previous ICH/PCH it was on the LPC bus.

Because iTCO_wdt devices may now appear on either the LPC bus or the
SMBUS we need to abstract the bus information into an agnostic structure
instead of the existing 'lpc_ich_info' which tightly integrates both the
lpc_ich and iTCO_wdt drivers.

The first patch introduces a platform data structure to handle this and
shuffles the existing code around. The other patches add the
device-specific information to the i2c-i801 and iTCO_wdt drivers.

Patches based against v4.2-rc4, if there's some other tree I should base
this on, please let me know.

Comments welcome!
