regulator: tps65023 : Adding support for DT

I started to add support for DT in this regulator, but I can't get a

have used tps6507x as an example until know...

Well, the best thing to do would be to backport the changes to add
support for DT parsing in the core and use that.  See "regulator: of:
Provide simplified DT parsing method" and preceeding commits in
mainline.  Otherwise what you've got looks basically OK from a quick
scan through.

I don't know for instance if a tps_board is needed (it would contain
only a struct regulator_init_data * so probably not very useful) ?

Probably not, no.

Below is my current status (I also have created a tps65023.dtsi in
arch/arm/boot/dts which is only a copy of tps6507x.dtsi so didn't copy
it here).

If you need to create a .dsti file for a regulator that's a warning sign
- it should be empty.  You'll want things in the particular board but
that ought to be board specific things rather than something that
applies to all boards using the regulator.
