Subject: [PATCH v2 3/3] mailbox: Kconfig: enable ARM SMC mailbox on 64-bit Allwinner SoCs
Date: Mon, 24 Jul 2017 00:23:26 +0100 [thread overview]
Message-ID: <1500852206-28771-4-git-send-email-andre.przywara@arm.com> (raw)
In-Reply-To: <1500852206-28771-1-git-send-email-andre.przywara@arm.com>
For 64-bit Allwinner SoCs there exist firmware implementations which
provide SCPI controlled handlers for DVFS, sensors and power domains.
To allow usage of this features, enable the required SMC mailbox when
Allwinner SoCs are supported by the kernel.
