From: Wolfram Sang Date: Wed, 5 Aug 2015 13:18:25 +0000 (+0200) Subject: i2c: rcar: add support for r8a7795 (R-Car H3) X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e7db0d34b38d56bbdb3d2d64c6233c53b77a3c6c;p=linux-beck.git i2c: rcar: add support for r8a7795 (R-Car H3) Enable the I2C core for this SoC. I add a new type because this version has new features (e.g. DMA) which will be added somewhen later.
