| * | irqchip/wpcm450: Fix memory leak in wpcm450_aic_of_init() | Wei Yongjun | 2022-11-26 | 1 | -0/+1 |
| | | | | | | | | | | | | If of_iomap() failed, 'aic' should be freed before return. Otherwise there is a memory leak.

| * | irq: remove handle_domain_{irq,nmi}() | Mark Rutland | 2021-10-26 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | | | Now that entry code handles IRQ entry (including setting the IRQ regs) before calling irqchip code, irqchip code can safely call generic_handle_domain_irq(), and there's no functional reason for it to call handle_domain_irq(). Let's cement this split of responsibility and remove handle_domain_irq() entirely, updating irqchip drivers to call generic_handle_domain_irq(). For consistency, handle_domain_nmi() is similarly removed and replaced with a generic_handle_domain_nmi() function which also does not perform any entry logic. Previously handle_domain_{irq,nmi}() had a WARN_ON() which would fire when they were called in an inappropriate context. So that we can identify similar issues going forward, similar WARN_ON_ONCE() logic is added to the generic_handle_*() functions, and comments are updated for clarity and consistency.

| * | irqchip: Add driver for WPCM450 interrupt controller | Jonathan Neuschäfer | 2021-04-07 | 1 | -0/+161 |
| The WPCM450 AIC ("Advanced Interrupt Controller") is the interrupt controller found in the Nuvoton WPCM450 SoC and other Winbond/Nuvoton SoCs. The list of registers if based on the AMI vendor kernel and the Nuvoton W90N745 datasheet. Although the hardware supports other interrupt modes, the driver only supports high-level interrupts at the moment, because other modes could not be tested so far.
