From 4eb0f25fa6538c8214e78ac31cdc070f20f78175 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 2 Jun 2015 18:04:03 +0800 Subject: [PATCH] ARM: dts: sun8i-a33: Add dts for Sinlinx SinA33 development board. The SinA33 is a core/SDK development board by Sinlinx. The core board does not have any connectors or pads, other than the pads used to connect it to the SDK board. The core board only has the A33 SoC, 2 RAM chips, an eMMC flash chip, the AXP223 PMIC, and supporting discrete components. eMMC is optional. The SDK board has a USB host, USB OTG, volume control and home buttons, audio input/output jacks, a micro-SD slot, camera and SDIO expansion headers, an LCD connector, and a GPIO expansion header, which has UARTs, MIPI DSI and I2C available. Only UART0 is enabled though.
