The list is in the commit description of "[PATCH 19/25] serial: sh-sci: Add support for optional external (H)SCK input": sh7723, sh7724, and r8a7740. Note that the list is probably incomplete, so I don't know if it's that useful to have it in the binding docs. Especially as I haven't verified yet that it actually works ;-) Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@linux-m68k.org In personal conversations with technical people, I call myself a hacker.
