Subject: [PATCH v4 0/2] Add JH8100 external interrupt controller support
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@starfivetech.com/
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@starfivetech.com/
