irqchip/irq-bcm2712-mip: Add ARCH_BCM2835 arch option

[PATCH] irqchip/irq-bcm2712-mip: Add ARCH_BCM2835 arch option

Posted by Peter Robinson 8 months, 1 week ago

The ARCH_BCM2835 is used widely for platforms enabling
the Raspberry Pi and some drivers that make use of this
driver are enabled using this or the BRCMSTB option so
add this too so the users that want RPi5 without all the
other STB devices end up with the driver as well.

irqchip/irq-bcm2712-mip: Enable driver when ARCH_BCM2835 is enabled

The BCM2712 MIP driver is required for Raspberry PI5, but it's not
automatically enabled when ARCH_BCM2835 is enabled and depends on
ARCH_BRCMSTB.

ARCH_BCM2835 shares drivers with ARCH_BRCMSTB platforms, but Raspberry PI5
does not require the BRCMSTB specific drivers, which are selected via
ARCH_BRCMSTB.

Enable the interrupt controller for both ARCH_BRCMSTB and ARCH_BCM2835.
