   4 Subject: [PATCH 1/5] dt-bindings: gpio: altera: Fix altr,interrupt-type
   5  property
   6
   7 The altr,interrupt-trigger property is not used by the driver.
   8 Instead, altr,interrupt-type is used by the driver and the driver
   9 does not probe if this property is not specified. Therefore, it
  10 is expected that there are no users of the -trigger property in
  11 the wild and that this is a typo in the documentation for the
  12 altera-pio controller. This patch fixes the typo.
