From: Guennadi Liakhovetski Date: Thu, 26 Sep 2013 11:06:01 +0000 (+0200) Subject: ARM: shmobile: only enable used I2C interfaces in DT on all Renesas boards X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=eda3a4fa9529341f2ce23374e5f295764d0b5838;p=linux-beck.git ARM: shmobile: only enable used I2C interfaces in DT on all Renesas boards Currently all I2C interfaces in all *.dtsi files for various Renesas SoCs are enabled by default. Switch them all off and only enable populated I2C interfaces in board-specific *.dts files.
