I don't think this will help. What you need to call in the clk driver is regmap_read/regmap_write but you can call it when syscon/regmap driver is initialized. Steffen: Can you point me to that floading patches? If they are useful we can try them and help with pushing them to the mainline. I don't think that there is any reasonable solution without using these patches. Thanks, Michal --=20 Michal Simek, Ing.
