Subject: [PATCH v3 17/24] ARM: at91: pm: add sama7g5 ddr controller
Date: Thu, 15 Apr 2021 13:50:03 +0300 [thread overview]
Message-ID: <20210415105010.569620-18-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <20210415105010.569620-1-claudiu.beznea@microchip.com>
Add SAMA7G5 DDR controller to the list of DDR controller compatibles.
At the moment there is no standby support. Adapt the code for this.
