From: Rob Herring Date: Mon, 21 Sep 2015 15:50:52 +0000 (-0500) Subject: dt-bindings: move backlight bindings under leds X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7755313e69aac99800c617ea835d86cd06f7f54c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git dt-bindings: move backlight bindings under leds Backlights are generally a subtype of LEDs at least from a software point of view if not always electrically. Move the bindings from the video directory to underneath the leds dir.
