Errors-To:

With the current range specified for the CPU interface there is an
error message at boot:
GIC: GICv2 detected, but range too small and irqchip.gicv2_force_probe not set
Setting irqchip.gicv2_force_probe=1 in bootargs results in:
GIC: Aliased GICv2 at 0x0000000010320000, trying to find the canonical range over 128kB
GIC: Adjusting CPU interface base to 0x000000001032f000
GIC: Using split EOI/Deactivate mode
Using the adjusted CPU interface base and 8K size results in only the
final line remaining and fully working system as well as /proc/interrupts
showing additional IPI3,4,5,6:
IPI3: 0 0 CPU stop (for crash dump) interrupts
IPI4: 0 0 Timer broadcast interrupts
IPI5: 0 0 IRQ work interrupts
IPI6: 0 0 CPU wake-up interrupts

On an MT7622 system, the kernel complains of not being able to detect the cache
hierarchy of CPU 0. Specify the shared L2 cache node in the device tree, in
order to fix this.

The MT7622 device tree never bothered to specify the number of virtual DMA
channels for the HSDMA controller, always falling back to the default value of
3. Make this value explicit, in order to avoid the following dmesg notification:
