kernel drivers drm/i915 turn off backlight.
I use Atom board that use drm/i915 driver to handle framebuffer.
I would like to use a function into this driver to turn off backlight but I nor sure how to make it.
For example, inside of intel_lvds.c, in drivers/gpu/drm/i915/ folder, there is a function to handle backlight:
static void intel_lvds_set_power(struct drm_device *dev, bool on)
static void intel_lvds_dpms(struct drm_encoder *encoder, int mode)
Could somebody help how to do it?
