Subject: ARM: dts: AM33xx: Add ti,mbox-send-noirq to wkup_m3 mailbox
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2800971f731e4491b71f44bf311452ab0f94a062;p=linux-beck.git

ARM: dts: AM33xx: Add ti,mbox-send-noirq to wkup_m3 mailbox

Add ti,mbox-send-noirq to wkup_m3 mailbox so that messages using
wkup_m3 mailbox are sent without triggering any further interrupts.
This is needed to achieve lower power numbers during CPU idle on
AM33xx.
