Subject: [PATCH 6/6] IPQ40xx: Add PRNG support
Date: Thu, 8 Oct 2020 22:05:14 +0200 [thread overview]
Message-ID: <20201008200514.2256778-7-robert.marko@sartura.hr> (raw)
In-Reply-To: <20201008200514.2256778-1-robert.marko@sartura.hr>
Since we now have the driver for Qualcomm PRNG HW, lets use it and add the necessary clocks and nodes.
