From b0e6ef46405353270595ffa35c21f4334c541189 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 10 Dec 2014 08:55:57 -0700 Subject: dm: i2c: tegra: Convert to driver model This converts all Tegra boards over to use driver model for I2C. The driver is adjusted to use driver model and the following obsolete CONFIGs are removed: - CONFIG_SYS_I2C_INIT_BOARD - CONFIG_I2C_MULTI_BUS - CONFIG_SYS_MAX_I2C_BUS - CONFIG_SYS_I2C_SPEED - CONFIG_SYS_I2C This has been tested on: - trimslice (no I2C) - beaver - Jetson-TK1 It has not been tested on Tegra 114 as I don't have that board.
