Please keep these sections (and the OF match data) sorted numerically.

My local patch had a few more entries. Feel free to add them:

+       { "i2c0",       4 },    /* PB10-PB11 */

> +	{ "mmc0",	2 },	/* PF0-PF5 */

Should be PC2-PC7. Everything else looks correct.

+       { "uart1",      2 },    /* PG6-PG7 */
+       { "uart2",      7 },    /* PB0-PB1 */
