Jose Alberto Meza e2b34b96e3 soc: microchip: mec172x: Add CPU barriers during low power entry/exit ... Follow ARM architecture recommendations: * Use Data Synchronization Barrier (DSB) instruction before WFI, to ensure that pending memory transactions complete before changing state. * To guarantee pend interrupts are recognized before subsequent operation, use ISB after CPSIE (__irq_enable) This prevents sporadicy delayed ISRs due to continous MEC172x entering/exiting deep sleep.
