This patch adds documentation of device tree bindings for the WVGA panel
Logic PD Type 28 display.

Signed-off-by: Adam Ford <aford173@gmail.com>

V4:  Update per Rob H's suggestions and copy other panel yaml example from 5.4-rc1
V3:  Correct build errors from 'make dt_binding_check'
V2:  Use YAML instead of TXT for binding

The example still fails to build here.

I cannot replicate the build error on 5.4-RC3 at least for this
binding on V4 of the patch.  I get build error on other bindings.

I took out some of the logs to make it less chatty.  I don't know
anything about yaml or what the expectations are, so if there is a
test beyond 'make dt_binding_check' please let me know.

Thank you,

Perhaps 'make -k' is needed because of the other failures. Or try on
top of linux-next which should all be fixed.

Thanks.  I didn't know about the '-k'  I replaced GPIO_ACTIVE_HIGH
with 0 and it seems to have fixed the error.
Sorry about all the noise.  Hopefully I did it right.  There is a V5
patch waiting now starting at [1]
