[v1] irqchip/irq-realtek-rtl: Add multicore support

[PATCH 0/2] irqchip/irq-realtek-rtl: Add multicore support

Posted by Markus Stockhausen 1 month ago

The Realtek Otto switch series consists of multiple devices.

- RTL838x: single core (Realtek proprietary IRQ controller)
- RTL839x: multi core (Realtek proprietary IRQ controller)
- RTL930x: multi core (Realtek proprietary IRQ controller)
- RTL931x: multi core (MIPS GIC controller)

The first three devices are supported by the irq-realtek-rtl
driver. Until now it only supports single core operation. So
the multi core devices cannot be driven in SMP mode.

Add multi core support to the driver.

Maybe you can give feedback on this series?

Thanks in advance.
