From 4f2122473363b569db652dc09029715ad808e1a6 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 10 Dec 2018 14:11:10 -0800 Subject: ARM: OMAP2+: Check also the first dts child for hwmod flags Until the board specific dts files are updated to have hwmod flags at the interconnect target module level, we want to keep things working both for old and new dts files. So let's also check the first child for hwmod flags. The module flags are for the whole module, so only the first child should ever have them.
