This patchset adds external interrupt controller driver for the StarFive JH81000 SoC. It can be used to handle high-level input interrupt signals. It also send the output interrupt signal to RISC-V PLIC. changes since v3: - Replaced "raw_spin_lock_irqsave" with "raw_spin_lock" - Replaced "raw_spin_unlock_irqsave" with "raw_spin_unlock" - Replaced "clear_bit" with "__clear_bit" v3: https://lore.kernel.org/all/20240221022647.5297-1-changhuang.liang@xxxxxxxxxxxxxxxx/ changes since v2: - Rebased on tag v6.8-rc4. - Added raw_spinlock_t - Added irq_domain_remove free domain - Updated struct declarations and initializers - Updated variable declarations - Dropped store clk in struct starfive_irq_chip - Replaced "starfive_intc_mod" with "starfive_intc_bit_set&starfive_intc_bit_clear" - Replaced "struct irq_domain *root_domain" with "struct irq_domain *domain" - Added reset_control_assert&clk_disable_unprepare helper functions to error recover v2: https://lore.kernel.org/all/20240130055843.216342-1-changhuang.liang@xxxxxxxxxxxxxxxx/ changes since v1: - Rebased on tag v6.8-rc1. - Dropped store reset_contorl. - Replaced "of_reset_control_get_by_index" with of_reset_control_get_exclusive - Printed the error code via %pe v1: https://lore.kernel.org/all/20240111023201.6187-1-changhuang.liang@xxxxxxxxxxxxxxxx/ Changhuang Liang (2): dt-bindings: interrupt-controller: Add starfive,jh8100-intc irqchip: Add StarFive external interrupt controller .../starfive,jh8100-intc.yaml | 61 ++++++ MAINTAINERS | 6 + drivers/irqchip/Kconfig | 11 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-starfive-jh8100-intc.c | 207 ++++++++++++++++++ 5 files changed, 286 insertions(+) create mode 100644 Documentation/devicetree/bindings/interrupt-controller/starfive,jh8100-intc.yaml create mode 100644 drivers/irqchip/irq-starfive-jh8100-intc.c -- 2.25.1
