Subject: atheros: pass UART IRQ number via function argument
X-Git-Tag: reboot~6492
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5c030111a9d57ce38efab652a24f8d242521ba99;p=openwrt%2Fstaging%2Flynxis.git

atheros: pass UART IRQ number via function argument

UART IRQ number could be different for different SoCs, so make them
configurable.
