This is what I understood from > past iterations of discussing this approach. Just FYI and to have the pointer in some archive: Had a look at recent threads because it appears that several pending changes have similar needs to adjust the kind of hardware access, while sharing common code to handle the actual clock item logic would be desirable. Please check "[PATCHv12 00/49] ARM: TI SoC clock DT conversion" from Tero Kristo as of 2013-12-20, which "in bypassing" introduces low level ops for register access (patches 06 and following). I suggested to separate this hardware access aspect out of the "TI SoC clock" series (almost missed the fact that it changes behaviour in common code), and to add regmap support or at least allow to do regmap on top of the ll_ops infrastructure. With the proposed generic approach all of us should be happy. The vast amount of ARM code should not experience any change, the queued PowerPC support can keep working, new TI SoC clocks can get implemented, Steven you can get regmap access, and more platforms may use the common code even if readl()/writel() won't fit them. Let's followup in Tero's v12 feedback thread to make that happen. virtually yours Gerhard Sittig -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr. 5, D-82194 Groebenzell, Germany Phone: +49-8142-66989-0 Fax: +49-8142-66989-80 Email: office@xxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
