[PATCH v2 0/2] ath79 misc irq controller

[Alexander Couzens]

v3:
 remove log line when setup ar7100 misc irq controller
 doc: write out {ar7100,ar7240} into two seperate lines

v2:
 move new IRQ_DECLARE just behind the new init for ar7100
 don't remove newline
 add log line when setup ar7100 misc irq controller
 improve commit message for missing irq ack handler

[PATCH v2 1/2] MIPS: ath79: set missing irq ack handler for ar7100-misc-intc irq chip

[Alexander Couzens]

The irq ack handler was forgotten while introducing OF support.
Only ar71xx and ar933x based devices require it.

[PATCH v2 2/2] MIPS: ath79: add irq chip ar7240-misc-intc

[Alexander Couzens]

The ar7240 misc irq chip use ack handler
instead of ack_mask handler. All new ath79 chips use
the ar7240 misc irq chip
