This patch adds a led-backlight driver (led_bl), which is similar to
pwm_bl except the driver uses a LED class driver to adjust the
brightness in the HW. Multiple LEDs can be used for a single backlight.

This patch adds basic support for a kernel driver to get a LED device.
This will be used by the led-backlight driver.
Only OF version is implemented for now, and the

On SoCs with DMM/TILER, we have two ways to allocate buffers: normal
dma_alloc or via DMM (which basically functions as an IOMMU). DMM can
map 128MB at a time, and we only map the DMM buffers when they are used
(i.e. not at alloc time). If DMM is present, omapdrm always uses

OMAP_BO_TILED does not make sense, as OMAP_BO_TILED_* values are not
bitmasks but normal values. As we already have OMAP_BO_TILED_MASK for
the mask, we can remove OMAP_BO_TILED and use OMAP_BO_TILED_MASK
instead.

omap_gem_new() has a comment about OMAP_BO_SCANOUT which does not make
sense. Also, for the TILER case, we drop OMAP_BO_SCANOUT flag for some
reason.
It's not clear what the original purpose of OMAP_BO_SCANOUT is, but
presuming it means "scanout buffer, something that can be
