Guys, sorry for the delay. This one did in fact not change too much after all. The biggest points that are still kind of open are the naming of the LEDs. If what is proposed here is acceptable it is not open from my side. The other big point was "using a generic gpio" driver as a basis. My current understanding of that point is, that such a driver does not yet exist. Meaning an introduction of the abstractions can and probably should wait for a second user. Without the second user it is just hard to test and find the right abstraction, plus we will end up with more code meaning more work for everyone. regards, Henning Am Mon, 29 Mar 2021 19:49:24 +0200 schrieb Henning Schild <henning.schild@xxxxxxxxxxx>: > changes since v2: > > - remove "simatic-ipc" prefix from LED names > - fix style issues found in v2, mainly LED driver > - fix OEM specific dmi code, and remove magic numbers > - more "simatic_ipc" name prefixing > - improved pmc quirk code using callbacks > > 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.
