Subject: [PATCH 02/28] coresight: platform: Make memory allocation helper generic
Date: Wed, 19 Jun 2019 13:52:52 -0600 [thread overview]
Message-ID: <20190619195318.19254-3-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20190619195318.19254-1-mathieu.poirier@linaro.org>
From: Suzuki K Poulose <suzuki.poulose@arm.com>
Rename the of_coresight_alloc_memory() => coresight_alloc_conns()
as it is independent of the underlying firmware type. This is in
preparation for the ACPI support.
