I do not think it is practically possible. Please see timing calculations in arch/arm/mach-omap2/gpmc-*, the way it is done for different peripherals are different, and we cannot expect gpmc driver to do those as that would require gpmc driver being aware of type of peripheral connected. And all those gpmc-* timing calculation needs to be done before driver is ready, they rely on functions like gpmc_get_fclk_rate(), which in turn requires the clk rate to be available before driver is probed.
