[PATCH 0/8] i2c: img-scb: fixes to support i2c on pistachio

[Sifan Naeem <sifan.naeem@imgtec.com>]

Following patches are required to fix the existing driver to
support i2c on pistachio.

Tested on Pistachio bub using an Adafruit I2C Non-Volatile FRAM Breakout
(256Kbit / 32KByte) eeprom.

Used i2c buildroot tools to test the eeprom and the other i2c blocks.
Also used dd commands to copy data to and then to dump data from the
eeprom. i2ctransfer was used to test repeated starts and verified
using a scope.

Cc: Stable kernel (v3.19+) <stable@vger.kernel.org>
