Bongsu Jeon b783ff46ef dt-bindings: net: nfc: s3fwrn5: Change I2C interrupt trigger type ... Change interrupt trigger from IRQ_TYPE_LEVEL_HIGH to IRQ_TYPE_EDGE_RISING for stable NFC I2C interrupt handling. Samsung's NFC Firmware sends an i2c frame as below. 1. NFC Firmware sets the GPIO(interrupt pin) high when there is an i2c frame to send. 2. If the CPU's I2C master has received the i2c frame, NFC F/W sets the GPIO low. NFC driver's i2c interrupt handler would be called in the abnormal case as the NFC FW task of number 2 is delayed because of other high priority tasks. In that case, NFC driver will try to receive the i2c frame but there isn't any i2c frame to send in NFC. It would cause an I2C communication problem. This case would hardly happen. But, I changed the interrupt as a defense code. If Driver uses the TRIGGER_RISING instead of the LEVEL trigger, there would be no problem even if the NFC FW task is delayed.
