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 + +config OMAP_GPMC + bool + select GPIOLIB + help + This driver is for the General Purpose Memory Controller (GPMC) + present on Texas Instruments SoCs (e.g. OMAP2+).
