A total of 134 pins can be spied on, which is the sum of: - 22 pins on bank GPIOX - 17 pins on bank GPIOY - 30 pins on bank GPIODV - 10 pins on bank GPIOH - 15 pins on bank GPIOZ - 7 pins on bank CARD - 19 pins on bank BOOT - 14 pins in the AO domain Acked-by: Kevin Hilman Acked-by: Rob Herring Signed-off-by: Martin Blumenstingl Signed-off-by: Marc Zyngier --- diff --git a/Documentation/devicetree/bindings/interrupt-controller/amlogic,meson-gpio-intc.txt b/Documentation/devicetree/bindings/interrupt-controller/amlogic,meson-gpio-intc.txt index 633e21c..a83f9a5 100644 --- a/Documentation/devicetree/bindings/interrupt-controller/amlogic,meson-gpio-intc.txt +++ b/Documentation/devicetree/bindings/interrupt-controller/amlogic,meson-gpio-intc.txt @@ -10,6 +10,7 @@ number of interrupt exposed depends on the SoC.
