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) Cc: Thomas Gleixner Cc: Jason Cooper Cc: Marc Zyngier Cc: devicetree@vger.kernel.org Cc: Andrew Lunn Cc: Aleix Roca Nonell Cc: James Tai Andreas Färber (8): dt-bindings: interrupt-controller: Add Realtek RTD1195/RTD1295 mux irqchip: Add Realtek RTD1295 mux driver arm64: dts: realtek: rtd129x: Add irq muxes and UART interrupts irqchip: rtd1195-mux: Add RTD1195 definitions ARM: dts: rtd1195: Add irq muxes and UART interrupts dt-bindings: interrupt-controller: rtd1195-mux: Add RTD1395 irqchip: rtd1195-mux: Add RTD1395 definitions arm64: dts: realtek: rtd139x: Add irq muxes and UART interrupts .../interrupt-controller/realtek,rtd1195-mux.yaml | 55 +++ arch/arm/boot/dts/rtd1195.dtsi | 20 + arch/arm64/boot/dts/realtek/rtd129x.dtsi | 22 + arch/arm64/boot/dts/realtek/rtd139x.dtsi | 22 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-rtd1195-mux.c | 463 +++++++++++++++++++++ 6 files changed, 583 insertions(+) create mode 100644 Documentation/devicetree/bindings/interrupt-controller/realtek,rtd1195-mux.yaml create mode 100644 drivers/irqchip/irq-rtd1195-mux.c
