| * | SMDK5250: Initialise and Enable DWMMC, support FDT and non-FDTAmar2013-06-13-169/+493

Supports both FDT and non-FDT. This patch creates a new file 'exynos5-dt.c' meant for FDT support. exynos5-dt.c: This file shall contain all code which supports FDT. Any addition of FDT support for any module needs to be added in this file. smdk5250.c: This file shall contain the code which supports non-FDT. version. Any addition of non-FDT support for any module needs to be added in this file. May be, the file smdk5250.c can be removed in near future when non-FDT is not required. The Makefile is updated to compile only one of the files exynos5-dt.c / smdk5250.c based on FDT configuration. NOTE: Please note that all additions corresponding to FDT need to be added into the file exynos5-dt.c. At same time if non-FDT support is required then add the corresponding updations into smdk5250.c. Signed-off-by: Amar <amarendra.xt@samsung.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

The old probe could hang the system under certain conditions (e.g. unconfigured pads). - The read/write/probe functions try to identify unconfigured bus. - Status functions now read irqstatus_raw as per TRM guidelines (except for OMAP243X and OMAP34XX). - Driver now supports up to I2C5 (OMAP5).

Adaptive Body-Bias ldos are present for some voltage domains starting with OMAP3630. There are three modes of operation: * Bypass - the default, it just follows the vdd voltage * Foward Body-Bias - applies voltage bias to increase transistor performance at the cost of power. Used to operate safely at high OPPs. * Reverse Body-Bias - applies voltage bias to decrease leakage and save power. Used to save power at lower OPPs.
