I don't have an Exynos4 to actually test this, so please let me know if I'm missing something here... but in order to hit the right HOST PHY register in the current upstream code, the Exynos4 code would need to have a hostphy_reg_offset of 4 somewhere in its samsung_usbphy_drvdata. In my latest checkout of Linus' tree (6c2580c) it does not (only Exynos5 sets that attribute), so it would default to 0 (thereby actually hitting the DEVICE register). If you want I can gladly provide another change on top of my patchset to fix that in the future... but it looks to me like it had been broken anyway for now. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
