package/panel-mipi-dbi-firmware: new package

Browse Source 
This package supports building and installing initialization command
firmware files for use with the panel-mipi-dbi DRM driver. To use the
package, initialization commands for the specific display(s) must be
provided in text form.

Build and install firmware files for the panel-mipi-dbi DRM
driver. The driver requires firmware file(s) to provide
initialization commands for the specific display(s) in
use. The initialization commands are written in text form
and converted to the binary format during the build.
If you select this package you will be prompted for the
initialization command file(s) to build firmware from.

help
Space separated list of initialization command files for
displays used with the panel-mipi-dbi driver. The files will
be converted to binary format and installed to /lib/firmware
in the rootfs. The binary files will use the basenames of
the input files, plus a .bin ending. The basename of each
file must match the first element of the "compatible" device
tree property of the display the file is for.
