Are you sure this is Innolux? Quick grep on Internet finds only BOE
panel with this TV123WAM[1].

The panel used here is innolux, which is a 2k panel. Where the BOE one
is a 1080p panel.
My doubts comes from the fact that Innolux uses different convention
for
panel naming, see for example [1].
According to this convention your panel should have name starting with:
N123ZDG-
TV123WAM follows BOE's convention.
Do you have datasheet, physical panel or something to ensure the name
is
correct?

The data sheet i have does not mention any version info/id of innolux
panel, so i took the
version name from a down stream patch we had earlier used to bring up
this panel.
Unfortunately i can not share the data sheet also as it is water marked
as confidential.
This panel patches are already merged in drm-misc, will upload a new
patch to remove tv123* name
and put some generic innolux panel name like innolux,2k

Changes in v1:
- Make use of simple panel driver instead of creating
a new driver for this panel (Sean Paul).
- Combine dt-binding and driver changes into one patch
as done by other existing panel support changes.
Changes in v2:
- Separate driver change from dt-binding documentation (Rob
Herring).
- Add the properties from simple-panel binding that are applicable
to
this panel (Rob Herring).
