Subject: [PATCH 3/4] firmware: arm_scmi: Check shmem property for channel availablity
Date: Fri, 27 Mar 2020 16:36:53 +0000	[thread overview]
Message-ID: <20200327163654.13389-4-sudeep.holla@arm.com> (raw)
In-Reply-To: <20200327163654.13389-1-sudeep.holla@arm.com>

Instead of declaring the channel availabilty unconditionally, let us
check for the presence of "shmem" property and return the channel
availablity accordingly.
