Subject: [PATCH v3 3/3] ARM: dts: vf610: add Miscellaneous System Control Module (MSCM)
Add the Miscellaneous System Control Module (MSCM) to the base
device tree for Vybrid SoC's. This module contains the peripheral
interrupt router, which handles the routing of the interrupts
for the two CPU cores. Almost all peripheral interrupts are
handled by the router, hence we make the MSCM module as default
interrupt parent for the SoC.
In a earlier commit the interrupt nodes were moved out of the
peripheral nodes and specified in the CPU specific vf500.dtsi
device tree. This allowed to use the base device tree vfxxx.dtsi
also for a Cortex-M4 specific device tree, which uses different
interrupt nodes due to the NVIC interrupt controller. However,
since the interrupt parent for peripherals is the MSCM module
independently which CPU the device tree is used for, we can move
the interrupt nodes into the base device tree vfxxx.dtsi again.
Depending on which CPU this base device tree will used with, the
correct parent interrupt controller has to be assigned to the
MSCM node (GIC or NVIC). The driver takes care of the parent
interrupt controller specific needs (interrupt-cells).
