Introduce an interrupt controller driver for Realtek DHC (Digital Home Center) SoCs. Change log: v3 -> v4: - Adjusted the allOf block to add constraints on the interrupts per variant - Adjusted the error path and label - Added the 'irq_domain_remove' to the error path - Removed the 'devm_kfree' from the error path - Replaced the 'irq_of_parse_and_map' with 'of_irq_get' - Replaced the 'raw_spin_lock' with 'raw_spin_lock_irqsave' - Adjusted the return value of the 'realtek_intc_subset' - Replaced the '~1' with macro 'CLEAN_INTC_STATUS' - Improved code comments and description - Fixed coding style issues - Fixed the incorrect control register in mask and unmask functions - Changed the 'EXPORT_SYMBOL' to the 'EXPORT_SYMBOL_GPL' - Renamed the 'realtek_intc_subset_cfg' to 'realtek_intc_mask' - Removed unused and unnecessary code - Removed 'irq_enable' and 'irq_disable' callback - Replaced the 'core_initcall' with 'module_init' - Removed redundant header files - Moved the function of suspend and resume to common code - Improved the description of config v2 -> v3: - Retested the bindings using the new version of the dtschema - Fixed the order of property items - Removed redundant files and replaced them with 'realtek,intc.yaml' - Replaced 'interrupts-extended' with 'interrupts' - Added a description for 'interrupts' - Reduced the example code - Resolved kernel test robot build warnings v1 -> v2: - Tested the bindings using 'make dt_binding_check' - Fixed code style issues - Resolved kernel test robot build warnings - Replaced spin_lock_irqsave with raw_spin_lock - Replaced magic number with macro - Removed the realtek_intc_set_affinity function James Tai (6): dt-bindings: interrupt-controller: Add support for Realtek DHC SoCs irqchip: Add interrupt controller support for Realtek DHC SoCs irqchip: Introduce RTD1319 support using the Realtek common interrupt controller driver irqchip: Introduce RTD1319D support using the Realtek common interrupt controller driver irqchip: Introduce RTD1325 support using the Realtek common interrupt controller driver irqchip: Introduce RTD1619B support using the Realtek common interrupt controller driver .../interrupt-controller/realtek,intc.yaml | 131 +++++++++++ drivers/irqchip/Kconfig | 44 ++++ drivers/irqchip/Makefile | 5 + drivers/irqchip/irq-realtek-intc-common.c | 211 ++++++++++++++++++ drivers/irqchip/irq-realtek-intc-common.h | 76 +++++++ drivers/irqchip/irq-realtek-rtd1319.c | 187 ++++++++++++++++ drivers/irqchip/irq-realtek-rtd1319d.c | 196 ++++++++++++++++ drivers/irqchip/irq-realtek-rtd1325.c | 196 ++++++++++++++++ drivers/irqchip/irq-realtek-rtd1619b.c | 186 +++++++++++++++ 9 files changed, 1232 insertions(+) create mode 100644 Documentation/devicetree/bindings/interrupt-controller/realtek,intc.yaml create mode 100644 drivers/irqchip/irq-realtek-intc-common.c create mode 100644 drivers/irqchip/irq-realtek-intc-common.h create mode 100644 drivers/irqchip/irq-realtek-rtd1319.c create mode 100644 drivers/irqchip/irq-realtek-rtd1319d.c create mode 100644 drivers/irqchip/irq-realtek-rtd1325.c create mode 100644 drivers/irqchip/irq-realtek-rtd1619b.c -- 2.25.1
