Subject: [PATCH] overlays: mipi-dbi-spi: width-mm and height-mm are
|
|
mandatory

There was a last minute change to the binding in commit 1ecc0c09f19f
|
|
("dt-bindings: display: panel: mipi-dbi-spi: Make width-mm/height-mm mandatory").
|
|
This was done so userspace can calculate DPI.
|
|
|
|
Update the overlay to ensure it will work with future kernels.
|
|
The driver changes won't be backported to rpi-5.15.
