This is v3 of the series introduces a ti-emif-sram driver to be used on am335x and am437x, based on v4.13-rc2. This version addresses some comments from Russell King and Johan Hovold in v2 found here [1]. Main changes are to patch two with grouping all the driver data into a single struct and allowing this to be passed to static functions in the driver, making sure all probe failures are handled so that we don't use invalid leftover data in any variables from the exported APIs, fixing a typo in the ASM code that caused botht he EMIF power management register and its shadow register to be saved to the same place, cleanup asm-offset macro definitions, and some general code fixups. This code is required for low-power modes to work on AM335x and AM437x and a forthcoming PM series for those platforms will depend on this series. After both this and the PM series are reviewed I will send the necessary device tree changes for both, but in the meantime all remaining patches for am335x and am437x PM can be found here [2].
