* i2c: rcar: Remove obsolete platform data supportGeert Uytterhoeven2015-10-201-10/+0
| | | | | | | | | | | Since commit 4baadb9e05c68962 ("ARM: shmobile: r8a7778: remove obsolete setup code"), Renesas R-Car SoCs are only supported in generic DT-only ARM multi-platform builds. The driver doesn't need to use platform data anymore, hence remove platform data configuration.

* i2c: add Renesas R-Car I2C driverKuninori Morimoto2012-10-081-0/+10
R-Car I2C is similar with SH7760 I2C. But the SH7760 I2C driver had many workaround operations, since H/W had bugs. Thus, it was pointless to keep compatible between SH7760 and R-Car I2C drivers. This patch creates new Renesas R-Car I2C driver. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>
