David Collins fcea656ff7 bif: qpnp-bsi: request BSI interrupts with level high triggering ... Request the BSI RX, TX and ERR interrupts using level high triggering instead of rising edge triggering. If an interrupt is edge triggered, then its interrupt handler will be called upon enabling the interrupt if it physically triggered while it was disabled in software. This leads to unexpected interrupt handler calls in the qpnp-bsi driver when the following sequence occurs: BIF transaction using interrupts (IRQs enabled), BIF transaction using polling (IRQs disabled), BIF transaction to enter interrupt mode bus state (IRQs enabled). Switching the interrupts to use level triggering fixes the issue because any interrupt physically triggered during a polling transaction with the BSI interrupts disabled will be ignored by the irq framework.
