10 There was a last minute change to the binding in commit 1ecc0c09f19f
11 ("dt-bindings: display: panel: mipi-dbi-spi: Make width-mm/height-mm mandatory").
12 This was done so userspace can calculate DPI.
13
14 Update the overlay to ensure it will work with future kernels.
15 The driver changes won't be backported to rpi-5.15.
