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").
