Subject: [PATCH v3 14/30] coresight: platform: Make memory allocation helper generic
Date: Tue, 7 May 2019 11:52:41 +0100 [thread overview]
Message-ID: <1557226378-10131-15-git-send-email-suzuki.poulose@arm.com> (raw)
In-Reply-To: <1557226378-10131-1-git-send-email-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.
