[PATCH v4 0/2] Move i2c sys_cfg register configuration to i2c driver

[Pankaj Dubey]

This patch series is moving i2c sys_cfg register configuration settings from
mach-exynos to i2c driver. It will help in removing soc_is_exynos kind of
macro usage from mach-exynos also it will help in removing static mapping of
SYS registers.

This series is based on latest kgene/for-next and on top of following
Exynos-PMU patches

[1]: ARM: Exynos: Convert PMU implementation into a platform driver
https://lkml.org/lkml/2014/10/6/89

Revision V3 of these patches was posted along with Exynos Chipid driver
support patch [2]. 

[2]: https://lkml.org/lkml/2014/5/10/31

Change since v3:
 - Rebased on latest kgene/for-next (SHA-ID: 2b5fa1d5dabb9af8f2da4f380bea8684f9b96f59)
 - This series consist of only two patches from v3 [1] (v3[1/6] and v3[2/6]).
 - Addressed Tomasz Figa and Wolfram Sang's comments.
 - Updated i2c DT binding information.

Changes since v2:
 - Reorganized patches as suggested by Tomasz Figa.
 - Addressed review comments of Tomasz Figa in i2c-s3c2410.c file.

Changes since v1:
 - Added patch to move i2c interrupt re-configuration code from exynos.c
   to i2c driver, as suggested by Arnd.
 - After above patch only user of SYS_I2C_CFG register is pm.c so moving
   save/restore of this register also into i2c driver.
 - Spiltted up exynos4 and exynos5 machine descriptors to get rid from
   soc_is_exynos4/exynos5 kind of macros, as suggested by Arnd.
 - Changed location of chipid driver to "drivers/soc".
 - Added drivers/base/soc.c provided infrastructure to make SoC specific 
   information avaible to user space via sysfs entry, as suggested by Arnd.
