769 * <1> Firstly, we should know what's the GPMI-clock means.
770 * The GPMI-clock is the internal clock in the gpmi nand controller.
771 * If you set 100MHz to gpmi nand controller, the GPMI-clock's period
772 * is 10ns. Mark the GPMI-clock's period as GPMI-clock-period.
775 * The frequency on the nand chip pins is derived from the GPMI-clock.
781 * G : the GPMI clock, such as 100MHz.
787 * The GPMI implements a feedback read strobe to sample the read data.
821 * tRP = (GPMI-clock-period) * DATA_SETUP
823 * 4.2) From the aspect of the GPMI nand controller:
827 * if (GPMI-clock-period > DLL_THRETHOLD)
828 * RP = GPMI-clock-period / 2;
830 * RP = GPMI-clock-period;
832 * Set the HW_GPMI_CTRL1:HALF_PERIOD if GPMI-clock-period
964 /* Wait 64 clock cycles before using the GPMI after enabling the DLL */ in gpmi_nfc_apply_timings()
987 /* Only MX28/MX6 GPMI controller can reach EDO timings */ in gpmi_setup_interface()
1803 * The tricky part in the GPMI/BCH controller is that it stores ECC bits
1810 * of the layout used by the GPMI controller.
1888 * The tricky part in the GPMI/BCH controller is that it stores ECC bits
1895 * of the layout used by the GPMI controller.
