Subject: [Patch 5/6] ARM: DRA7: hwmod: Add VPE nodes
Date: Thu, 12 Oct 2017 14:27:18 -0500	[thread overview]
Message-ID: <20171012192719.15193-6-bparrot@ti.com> (raw)
In-Reply-To: <20171012192719.15193-1-bparrot@ti.com>

Add hwmod entries for VPE (Video Processing Engine) hardware block
found in DRA7x family of devices.

DRA75x_DRA74x_ES1.1 Version T Technical Reference Manual
(Literature Number SPRUHI2T) states that VPE only support NO_STANDBY,
FORCE_STANDBY, NO_IDLE, FORCE_IDLE and SMART_IDLE.
The hwmod flags were set to reflect this fact and make sure that
both are software supervised (SWSUSP).
