memory: emif: add basic infrastructure for EMIF driver
EMIF is an SDRAM controller used in various Texas Instruments SoCs. EMIF supports, based on its revision, one or more of LPDDR2/DDR2/DDR3 protocols. Add the basic infrastructure for EMIF driver that includes driver registration, probe, parsing of platform data etc. Signed-off-by: Aneesh V <aneesh@ti.com> Reviewed-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Reviewed-by: Benoit Cousson <b-cousson@ti.com> [santosh.shilimkar@ti.com: Moved to drivers/memory from drivers/misc] Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Tested-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

+ This driver is for the EMIF module available in Texas Instruments
+ SoCs. EMIF is an SDRAM controller that, based on its revision,
+ supports one or more of DDR2, DDR3, and LPDDR2 SDRAM protocols.
+ This driver takes care of only LPDDR2 memories presently. The
+ functions of the driver includes re-configuring AC timing
+ parameters and other settings during frequency, voltage and
+ temperature changes
