Subject: mfd: palmas: Add rtc irq number as irq resource for palmas-rtc
X-Git-Tag: v3.9-rc1~92^2~64
X-Git-Url: http://git.cascardo.eti.br/?a=commitdiff_plain;h=a36516b016f52f0f6e5284025e3487f63b4be33b;p=cascardo%2Flinux.git

mfd: palmas: Add rtc irq number as irq resource for palmas-rtc

Palma RTC is capable of generating alarm interrupt. Pass the alarm interrupt
as IRQ_RESOURCE for palmas-rtc sub device driver so that rtc driver can get
irq as platform_get_irq().

Also pass the irq domain in mfd_add_devices() to properly offset the irqs for
sub devices. This is needed when adding device through DT.
