From mboxrd@z Thu Jan 1 00:00:00 1970 From: Milo Kim Subject: [PATCH] ARM: dts: sun8i: Add SPI controller node in H3 Date: Wed, 19 Oct 2016 22:46:08 +0900 Message-ID: <20161019134608.12850-1-woogyom.kim@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: "linux-arm-kernel" Errors-To: linux-arm-kernel-bounces+linux-arm-kernel=m.gmane.org@lists.infradead.org To: Maxime Ripard , Chen-Yu Tsai Cc: Milo Kim , devicetree@vger.kernel.org, linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org List-Id: devicetree@vger.kernel.org H3 supports two SPI controllers. Four pins (MOSI, MISO, SCLK, SS) are configured through the pinctrl subsystem. It is almost same as A31 SPI except buffer size, so those DT properties are reusable.
