arm: tegra: tegratab: disable prism in kernel side
Min-wuk Lee [Thu, 13 Jun 2013 05:03:53 +0000 (14:03 +0900)]
Set prism enable node to 0 in kernel side. Brightness change
and color saturation can be visible during kernel dc probe
depending on screen image since splash screen drawn in bootloader
didn't enable prism. Prism on / off will be handled
by power mode selection in user land.
