[PATCH] video: move Versatile CLCD helpers
Linus Walleij
linus.walleij at linaro.org
Wed May 28 06:16:57 PDT 2014
This moves the Versatile-specific helper code and panel database
down into the drivers/video folder next to the CLCD driver
itself, preserving the config symbol but also moving the header
to platform data.
This is necessary to rid the Integrator of this final <plat/*>
inclusion dependency and get us one less user of the
plat-versatile folder.
