Subject: [PATCH 00/11] Modular Broadcom irqchip drivers

Hi Thomas, Marc,

This patch series aims at allowing the 3 interrupt controller drivers
used on Broadcom STB platforms to be built as modules in order for those
to be shipped in a GKI enabled system (Android).

The irq-bcm7038-l1 requires us to export a number of symbols, which is
not great, but there are not obvious solutions other than adding
accessor functions to get the same information.

Assuming you are happy with the changes though, please do take the last
two changes as well through your tree.

Thanks!

Florian Fainelli (11):
  arch: Export cpu_logical_map to modules
  genirq: Export irq_to_desc() again to modules
  genirq: Export irq_set_affinity_locked()
  irqchip/irq-bcm7038-l1: Switch to IRQCHIP_PLATFORM_DRIVER
  irqchip/irq-brcmstb-l2: Switch to IRQCHIP_PLATFORM_DRIVER
  genirq: Export irq_gc_{unmask_enable,mask_disable}_reg
  of/irq: Export of_irq_count to drivers
  genirq: Export irq_gc_noop()
  irqchip/irq-bcm7120-l2: Switch to IRQCHIP_PLATFORM_DRIVER
  arm64: broadcom: Removed forced select of interrupt controllers
  ARM: bcm: Removed forced select of interrupt controllers
