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

[Markus Stockhausen]

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.
