Geert Uytterhoeven 77287a2cab ARM: shmobile: sh73a0 legacy: Set .control_parent for all irqpin instances 
commit b0ddb319db3d7a1943445f0de0a45c07a7f3457a upstream.

The sh73a0 INTC can't mask interrupts properly most likely due to a
hardware bug. Set the .control_parent flag to delegate masking to the
parent interrupt controller, like was already done for irqpin1.

Without this, accessing the three-axis digital accelerometer ADXL345
on kzm9g through /dev/input/event1 causes an interrupt storm, which
requires a power-cycle to recover from.

This was inspired by a patch for arch/arm/boot/dts/sh73a0.dtsi from
Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>.
