Date: Wed, 17 Jul 2019 15:58:01 +0530	[thread overview]
Message-ID: <20190717102804.27202-7-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20190717102804.27202-1-anshuman.gupta@intel.com>

Added POWER_DOMAIN_VIDEO power domain and added its helper stuff.
POWER_DOMAIN_VIDEO is a hook to "DC5 Off" power well.
which can disallow DC5/6 in order to allow dc3co.
