From 392ea5dd0ff265f7557405fcbdf35acd34cf4ab8 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Fri, 22 Dec 2017 11:26:03 +0200 Subject: [PATCH] ARM: OMAP2+: hwmod_core: enable optional clocks before main clock The optional clocks must be enabled before the main clock after the transition to clkctrl controlled clocks is done. Otherwise the module we attempt to enable might be stuck in transition.
