From mboxrd@z Thu Jan 1 00:00:00 1970 From: Linus Walleij Subject: [PATCH 2/5 v2] dma: pl08x: Add Faraday FTDMAC020 to compatible list Date: Sat, 20 May 2017 23:42:51 +0200 Message-ID: <20170520214254.21541-2-linus.walleij@linaro.org> References: <20170520214254.21541-1-linus.walleij@linaro.org> Return-path: In-Reply-To: <20170520214254.21541-1-linus.walleij-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org> Sender: devicetree-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: Vinod Koul , dmaengine-u79uwXL29TY76Z2rM5mHXA@public.gmane.org Cc: Janos Laube , Paulius Zaleckas , linux-arm-kernel-IAPFreCvJWM7uuMidbF8XUB+6BGkLq7r@public.gmane.org, Hans Ulli Kroll , Florian Fainelli , Kuo-Jung Su , Linus Walleij , devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: devicetree@vger.kernel.org This augments the PL08x bindings to include the Faraday Technology FTDMAC020 DMA engine, as it is clearly a derivative of the PL08x PrimeCell. Also specify that it needs the special peripheral ID specified to work properly.
