Are you looking for correlation with the schematics, or something else;
my interpretation is that the names in the patch already appear to describe
what the signals are used for.

In particular, in your example, you wrote "EMMC" rather than "SD2". I'm not
sure where the name "EMMC" comes from, nor why there's no number in the name
"EMMC".

For reference, the schematics for these two boards use the following signal
names:

Harmony:
SDIO2_CD, SDIO2_WP, EN_VDDIO_SD
HSMMC_CD, HSMMC_WP, EN_VDDIO_SDMMC

Seaboard:
SDIO32_CD, SDIO3_WP, EN_VDDIO_SD

Would those be OK?

Thanks.
