This include is only needed to get GPMI_NFC_DRIVER_MX23? Then I suggest
to hardcode the clock name.

Doesn't the driver handle enabling the clock?

maybe use a macro to define this and res_imx28?

You can save these cpu_is_mx23 calls by letting mxs23_add_gpmi pass
res_imx23 (with a better name) to mxs_add_gpmi as is done by the other
functions. (Or alternatively implement mxs23_add_gpmi as function.)

I'd prefer "imx23-gpmi" et al here. Is the 8 in "gpmi-nfc-mx508"
intended?

IMHO adding the device to machines should be a seperate patch.
