The K3 AM65x and J721E SoCs have the next generation of the PRU-ICSS
IP,
commonly called ICSSG. The PRUSS INTC present within the ICSSG supports
more System Events (160 vs 64), more Interrupt Channels and Host
Interrupts
(20 vs 10) compared to the previous generation PRUSS INTC instances.
The
first 2 and the last 10 of these host interrupt lines are used by the
PRU and other auxiliary cores and sub-modules within the ICSSG, with 8
host interrupts connected to MPU. The host interrupts 5, 6, 7 are also
connected to the other ICSSG instances within the SoC and can be
partitioned as per system integration through the board dts files.
Enhance the PRUSS INTC driver to add support for this ICSSG INTC
instance. This support is added using specific compatible and match
data and updating the code to use this data instead of the current
hard-coded macros. The INTC config structure is updated to use the
higher events and channels on all SoCs, while limiting the actual
processing to only the relevant number of events/channels/interrupts.

v2->v3:
- Change patch order: use it directly after "irqchip/irq-pruss-intc:
Implement irq_{get,set}_irqchip_state ops" and before new
"irqchip/irq-pruss-intc: Add event mapping support" in order to
reduce
diff.
The diff would be even smaller if you introduced a variable number of
inputs the first place, i.e. in patch #2. Most if this patch just
retrofits it. Please squash these changes into that initial patch,
and only add the platform stuff here.
Yeah, all the variables were introduced in this patch based on patch
history. Until this new IP came, we haven't had a need to use variables
in the original driver code. That's also the reason for this being a
separate patch rather than squashed into the original patch.

Sure I will do that.
Thank you,
Grzegorz
