Subject: [PATCH v9 21/23] arch: arm64: dts: meson: s4: add crypto node
Date: Tue, 20 Aug 2024 17:56:21 +0300	[thread overview]
Message-ID: <20240820145623.3500864-22-avromanov@salutedevices.com> (raw)
In-Reply-To: <20240820145623.3500864-1-avromanov@salutedevices.com>

This patch adds a crypto node declaration for Amlogic S4-series.
With the Amlogic crypto driver we can use HW implementation
of SHA1/224/256 and AES algo.
