This misunderstanding led to the 0 being used as vIRQ which is no-no and platform APIs unveil this after the commit a85a6c86c25b ("driver core: platform: Clarify that IRQ 0 is invalid"). With this the Intel Broxton Whiskey Cove PMIC driver has to be fixed all over the places. In this series two immediate fixes as reported recently and we have drivers for (patches 1 & 2) followed by the patch that prepares the same fix for the devices that have no in-tree drivers yet. At the end it is a fix for IRQ domain debugging (when enabled), but it requires quite recent patches in IRQ domain and regmap IRQ subsystems, which is reflected in the Depends-on tag (I can't use Fixes, as this doesn't fix anything related to that). The series touches a couple of subsystems as the respective drivers has to be fixed simultaneously. The idea is to proceed the series via MFD tree to where the main driver belongs. I have tested this on Intel Joule SoM (Apollo Lake SoC).
