Hello,

This series adds two IRQ muxes for the Realtek RTD1295 and RTD1195 SoCs.

The implementation is based on register offsets seen in the vendor DT,
split up into two separate nodes, as well as code from QNAP's rtk119x and
Synology's RTD1293/96 GPL code dumps.

v3 does various cleanups, renames variables, reworks unmask vs. enable/disable
and adds an isr/scpu_int_en map as well as full RTD1195 support.

More experimental patches at:
https://github.com/afaerber/linux/commits/rtd1295-next

Have a lot of fun!

Cheers,
Andreas

v2 -> v3:
* Rebased, adding nodes to rtd129x.dtsi instead of rtd1295.dtsi
* Adopted {readl,writel}_relaxed() (Marc)
* Adopted spin_lock_irqsave() (Marc)
* Implemented RTD1195
* Implemented mapping for non-linear bits such as i2c3

v1 -> v2:
* Rebased, avoiding dependency on reset series for DT nodes
* Don't forward set_affinity to GIC (Marc)
* Added more spinlocks (Marc)
* Code cleanups
* Investigated quirk
* Fixed spinlock initialization (Andrew)
