-Subject: [PATCH] mcp2515: Use DT-supplied interrupt flags
-
-The MCP2515 datasheet clearly describes a level-triggered interrupt
-pin. Therefore the receiving interrupt controller must also be
-configured for level-triggered operation otherwise there is a danger
-of a missed interrupt condition blocking all subsequent interrupts.
-The ONESHOT flag ensures that the interrupt is masked until the
-threaded interrupt handler exits.
-
-Rather than change the flags globally (they must have worked for at
-least one user), allow the flags to be overridden from Device Tree
-in the event that the device has a DT node.
-
-See: https://github.com/raspberrypi/linux/issues/2175
