I'm now seeing the following error on omap5 during boot:

(NULL device *): Failed to create dummy-scm_conf@0 debugfs directory
This log means failed to init regmap debugfs with device(NULL) and name("scm_conf@0"), which likely to be called from of_syscon_register() with np fullname("scm_conf@0").

So my guess would be there're more than one syscon dts nodes named "scm_conf@0".

For omap5 and scm_conf@0, should be these 2:
scm_conf: scm_conf@0 {
compatible = "syscon";
scm_wkup_pad_conf: scm_conf@0 {
compatible = "syscon", "simple-bus";

Maybe try to rename one of them(for example, rename the second one to "scm_wkup_pad_conf@0").
