Hi all, in p3 not too much was left open so i hope this might be the last and might be quick. The two points that have been open where: 1 wish to split wdt driver into two 2 wish to use pinctrl for LEDs/WDT 1 was ignored for now. We can split later when we add more devices. It remains unclear if splitting is the way to go when more devices come. Could also be that it would become too many and spreading code over many files could make maint harder. Plus a split of wdt alone would make things inconsistent with LEDs. And if we did split that we would end up with even more files/drivers. 2 can not be done because pinctrl does not probe on any of the PCs. There are patches floating around but still under review/construction. There is no technical conflict it is more an ordering issue. So i kindly ask to let these drivers in and not have them stuck behind the P2SB patches. I once offered to wait, but its been many months. regards, Henning Am Fri, 26 Nov 2021 15:10:23 +0100 schrieb Henning Schild <henning.schild@xxxxxxxxxxx>: > changes since v3: > > - fix io access width and region reservations > - fix style in p1 > > 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.
