Hi, all
In Linux gpmi nand driver for imx28evk, I can not find the code to setup timing parameters into hardware registers. For example, in gpmi-nfc-hal-v1.c, the funtion set_timing(...) doesn't really write nfc's hardware registers, the function is as follows:
/**
* set_timing() - Configures the NFC timing.
*
* @this: Per-device data.
* @timing: The timing of interest.
*/
static int set_timing(struct gpmi_nfc_data *this,
const struct gpmi_nfc_timing *timing)
{
struct nfc_hal *nfc = this->nfc;
/* Accept the new timing. */
nfc->timing = *timing;
/* Return success. */
return 0;
}
Some helps are needed for me to figure this problem out. Thanks very much.

yes.
But if the EDO mode is enabled with the ONFI nand.
The timing setting will be changed.
You can read the latest Linus's kernel for reference.
