From: Stefan Roese Date: Fri, 23 Oct 2015 10:56:12 +0000 (+0200) Subject: arm: sun7i: Add sun7i-a20-icnova-swac.dts X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=329f25b343c5fdd74da7a4c0520b24a732993ba8;p=linux-beck.git arm: sun7i: Add sun7i-a20-icnova-swac.dts This baseboard from SWAC is equipped with the ICnova-A20 SoM from Incircuit. This board is equipped with the following interfaces / devices: - 512 MiB SDRAM - 4 GiB MLC NAND (Micron MT29F32G08CBACAWP or Hynix H27UBG8T2BTR) - USB host - LCD 800x480 - HDMI - CAN Note that the NAND support is still missing. As its currently not supported in mainline for sunxi and especially for these MLC devices. The original plan was to also provide a dtsi for the ICnova SoM, to put all the SoM internal nodes / properties there. But as I don't have a clear overview of the SoM specific and baseboard specific differences, I'm putting all in one dts for now. Once somebody pushed support for some other baseboard using the A20 SoM from Incircuit (e.g. the ADB4006 reference design), this should be separated.
