You could post support for sdio0 and adio1? Also: it's really handy if emmc is 0. See below: I don't think it's great to use the ID to find the sysconfig registers. > So we can get ctrl_id: > ctrl_id = of_alias_get_id(host->dev->of_node, "mshc"); Somehow I hadn't realized that was there. I guess we could use that too. I'd vote to remove that and use the standard "mmc" numbering (and get some momentum to land those patches). If you want I'll repost using the mshc stuff, though. > and can get offset of registers: > offset = 0x200 + ctrl_id * 8 + 4 * drive_or_sample I thought the plan was to actually implement the phase stuff as a clock driver. ...even if we didn't, I'd rather not rely on ID like this to find the right address. It's really non-obvious. -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
