Merge branch 'nfc-s3fwrn5-Change-I2C-interrupt-trigger-to-EDGE_RISING'
Bongsu Jeon says:
====================
nfc: s3fwrn5: Change I2C interrupt trigger to EDGE_RISING
For stable Samsung's I2C interrupt handling, I changed the interrupt
trigger from IRQ_TYPE_LEVEL_HIGH to IRQ_TYPE_EDGE_RISING and removed
the hard coded interrupt trigger type in the i2c module for the flexible
control.
1/2 is the changed dt binding for the edge rising trigger.
2/2 is to remove the hard coded interrupt trigger type in the i2c module.
ChangeLog:
v2:
2/2
- remove the hard coded interrupt trigger type.
