PATCH 1/1 ARM: dts: imx6: remove bogus interrupt-parent from CAAM node
The interrupt-parent property is not needed as it is inherited from the parent bus and in the case of the CAAM node actively points to the wrong interrupt controller (GIC instead of GPC). This leads to the CAAM IRQs not getting unmasked at the GPC level, leaving them unable to wake the CPU from wait mode, potentially impacting performance of the CAAM unit when CPUidle is enabled.
