Finally, I got your point. You want me to drop
"samsung,ufs-shareability-reg-offset" and put the offset like below.
ufs_0: ufs0@17e00000 {
<snip>
samsung,sysreg = <&syscon_fsys2 0x710>;
To be added ufs_1 like below
ufs_1: ufs0@17f00000 {
<snip>
samsung,sysreg = <&syscon_fsys2 0x714>;
I'll resend the patch with your suggestion.
Krzysztof, could you please hold below on? Or Do I need to make an
additional patch?
