This driver has fb_pan_display() which I assume works. However, you also
need to set ypanstep and/or xpanstep and/or ywrapstep to a nonzero
value, depending on the hardware/drive capability.
True, this function is here because one of our products can do pan display.
The technique is not used for the moment but will be in a future version
of this driver.

Do you really need to pre-fill pseudo_palette[]? The contents are going
to be overwritten by the console anyway (The pseudo_palette is for
fbcon's use only).
Ok, I have tested it with fbcon and no pre-fill : colors seem ok.
You can also include pseudo_palette[] as part of struct
atmel_lcdfb_info, then in your probe routine:
info->pseudo_palette = par->pseudo_palette;
to reduce the size of the kernel image.
Done.
+static inline u_int chan_to_field(u_int chan, const struct fb_bitfield *bf)
Might as well change u_int to u32 or unsigned int, for consistency.
Ok, changed to unsigned int.

memset_io?
ok, modified.

Wrong goto? Should be goto free_info?
Right. modified to "goto free_info".
+release_intmem:

Unnecessary curly braces
I like curly braces... Anyway, removed.
Thanks you for your comments.
I resend a modified driver now in the following email.
