I added the patch that is planned to fix the problem I reported on top of: 76b069b1cb20 spmi: spmi-pmic-arb: enable the SPMI interrupt as a wakeup source which is the last patch in the series that included the patch that I reported a problem with. My board boots fine at that point, so I am fairly confident that my further boot issues have yet another cause, and that the fix on its way upstream should fix the specific problem that I reported. -Frank
