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:
https://elixir.bootlin.com/linux/latest/source/arch/arm/boot/dts/omap5.dtsi#L167
                                scm_conf: scm_conf@0 {
                                        compatible = "syscon";

https://elixir.bootlin.com/linux/latest/source/arch/arm/boot/dts/omap5.dtsi#L313
                                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").
