Here's what I came up with.


+       struct data {const char *name; int tx_offset;};
+       static const struct data ok_list[] = {
+       /*      {"armada-3700-uart", ?},        */
+               {"exynos4210-uart", 0x20},
+       /*      {"ls1021a-lpuart", ?},          */
+       /*      {"meson-uart", ?},              */
+       /*      {"mt6577-uart", ?},             */
+               {"ns16550", 0},
+               {"ns16550a", 0},
+               {"pl011", 0},
+               {NULL, 0}
+       };
