Subject: [PATCH] ARM: dts: BCM2711 AON_INTR2 generates IRQ edges
|
|
|
|
THe AON_INTR2 controller manages the HDMI interrupts, combining them
|
|
into a single interrupt passed to the GIC. bcm2711.dtsi declares the
|
|
interrupt as being IRQ_TYPE_LEVEL_HIGH, but it should be
|
|
IRQ_TYPE_EDGE_RISING. Most of the time the distinction shouldn't
|
|
matter, but there is a small possibility of losing interrupts unless
|
|
it is corrected.
