Subject: [PATCH 1/2] reset: imx7: Add support for i.MX8MM SoC
Date: Mon, 1 Jul 2019 17:39:43 +0800 [thread overview]
Message-ID: <20190701093944.5540-1-Anson.Huang@nxp.com> (raw)
From: Anson Huang <Anson.Huang@nxp.com>
i.MX8MM SoC has a subset of i.MX8MQ IP block variant, it can reuse
the i.MX8MQ reset controller driver and just skip those non-existing
IP blocks, add support for i.MX8MM SoC reset control.
