* Add RTC with LSI for BP, GP, WP * disable jenkins temporarily, REVERT! * experiments * cleanup is still needed * cppcheck unused suppress * raise deepsleep limit timeout to 120sec * more experiments on usb_enumerated * continue * soft_disconnect * almost done * not enough * no ignition * still don't like it.. * rename to has_rtc_battery * clock_source on the way!? * delay 3 sec * works on C3, needs test on C2 * And this is for C2 * disable bootkick * misra 10.4 * .. * .. * set power state the right way * change that * seems don't need that? check on C2/C3 * partially works on RP... * comments (will work after rebase) * change fault name * switch to manual activation mode * Revert "disable jenkins temporarily, REVERT!" This reverts commit 578d425fa7ba256f513c1c6ca54a00d69d78f53e. * my dear pedal!
