From 8ff42da411474893ae373d4280ea88954fa97fcc Mon Sep 17 00:00:00 2001 From: Roger Quadros Date: Fri, 17 Mar 2017 10:58:18 +0200 Subject: ARM: OMAP2+ hwmod: Allow modules to disable HW_AUTO Introduce HWMOD_CLKDM_NOAUTO flag that allows the hwmod's clockdomain to be prevented from HW_AUTO while the hwmod is active. This is needed to workaround some modules which don't function correctly with HW_AUTO. e.g. DCAN on DRA7.
