Subject: [PATCH v4 0/8] ARM: Realtek RTD1195/RTD1295/RTD1395 IRQ mux

Hello,

This series adds two IRQ muxes for the Realtek RTD1195, RTD1295 and RTD1395
SoC families.

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

v3 -> v4:
* Drop no-op .irq_set_affinity callback (Thomas)
* Clear all interrupts (James)
* Updated SPDX-License-identifier
* Use tabular formatting (Thomas)
* Adopt different braces style (Thomas)
* Use raw_spinlock_t (Thomas)
* Shortened callback name (Thomas)
* Fixed of_iomap() error handling
* Don't mask unmapped NMIs
* Cache SCPU_INT_EN (Thomas)
* Renamed binding and source files
* Dropped UART1/UART2 TO interrupts
* Expanded commit messages
* Added RTD1395 patches

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)
