[PATCH 0/3] RK356x VOP2: Change register space names

[Sascha Hauer]

The VOP2 driver sitting in next uses named register spaces, but the
binding lacks documentation for that. Add the missing documentation
and while at it take the opportunity to rename the register spaces
from too generic "regs" to "vop" and from "gamma_lut" to better looking
"gamma-lut".

[Sascha Hauer]

The VOP2 driver relies on reg-names properties, but these are not
documented. Add the missing documentation, make reg-names mandatory
and increase minItems to 2 as always both register spaces are needed.

"regs" seems to generic when there are multiple register spaces, so
rename that one to "vop". Also change "gamma_lut" to better looking

[PATCH 3/3] arm64: dts: rockchip: rk356x: Change VOP2 register space names

[Sascha Hauer]

"regs" seems to generic when there are multiple register spaces, so
rename to "vop". Also, replace "gamma_lut" with better looking
"gamma-lut". This has been changed in the driver and binding
documentation as well.

I'm not sure how the DT-people work - if they only track the devicetree list
or their x+dt@kernel.org accounts or some mixture, but the patch was
missing the maintainer email addresses - I've added them here now :-) .

The change looks good to me and as I merged the original binding
into drm-misc only some days ago, we also don't have a backwards-
compat issue yet, so hopefully DT-people will think similarly .

You ran the dt checks, right? This should give you a warning. The 
correct thing is drop minItems if there's always 2 entries.

I only see what is in DT PW. Since I'm copied on almost everything that 
goes to the DT list, CC'ing me has almost no effect.

It will fail checks... I can't run them as this doesn't apply, so 
hopefully someone does. Or I can complain when next breaks.
