From: Felix Fietkau Date: Thu, 17 Jul 2014 16:36:33 +0000 (+0000) Subject: atheros: simplify AR2315 misc IRQ (un)masking X-Git-Tag: reboot~6489 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0a785ebb7d6e86c0d91c5baff1b021294004bd8d;p=openwrt%2Fstaging%2Fblogic.git atheros: simplify AR2315 misc IRQ (un)masking Currently AR5312 misc IRQ numbers are used for AR2315+ chips, what cause us to use switch-case to map IRQ number to ISR bit. Introduce AR2315 specific misc IRQs set and simplify interrupt (un)mask operation.
