Currently, there is no way to specify a recommended bpp for a generic dpi display. This patch adds a mechanism for doing so. If no recommended bpp is specified by the driver, we fall back to the default recommended bpp function Signed-off-by: Daniel Morsing <redacted> --- drivers/video/omap2/displays/panel-generic-dpi.c | 15 +++++++++++++++ 1 files changed, 15 insertions(+), 0 deletions(-)
