changes since v1:

- fixed lots of style issues found in v1
- (debug) printing
- header ordering
- fixed license issues GPLv2 and SPDX in all files
- module_platform_driver instead of __init __exit
- wdt simplifications cleanup
- lots of fixes in wdt driver, all that was found in v1
- fixed dmi length in dmi helper
- changed LED names to allowed ones
- move led driver to simple/
- switched pmc_atom to dmi callback with global variable

This series adds support for watchdogs and leds of several x86 devices
from Siemens.

It is structured with a platform driver that mainly does identification
of the machines. It might trigger loading of the actual device drivers
by attaching devices to the platform bus.

The identification is vendor specific, parsing a special binary DMI
entry. The implementation of that platform identification is applied on
pmc_atom clock quirks in the final patch.

It is all structured in a way that we can easily add more devices and
more platform drivers later. Internally we have some more code for
hardware monitoring, more leds, watchdogs etc. This will follow some
day.

Henning Schild (4):
platform/x86: simatic-ipc: add main driver for Siemens devices
leds: simatic-ipc-leds: add new driver for Siemens Industial PCs
watchdog: simatic-ipc-wdt: add new driver for Siemens Industrial PCs
platform/x86: pmc_atom: improve critclk_systems matching for Siemens
PCs
