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

This would give us a WARN_ON() if the pin/unpin calls are unbalanced.

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.

Add omap_gem_unpin_locked() which is a version of omap_gem_unpin() that
expects the caller to hold the omap_obj lock.

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
about that)
- rework the refcount part a bit.

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.

- removed the option to use a regulator. It should be handled by the LED
core
- don't make any change to the LED core (not needed anymore)
Jean-Jacques Hiblot (3):
leds: populate the device's of_node
leds: Add managed API to get a LED from a device driver
dt-bindings: backlight: Add led-backlig
If initialization data is available and its fwnode is actually a of_node,
store this information in the led device's structure. This will allow the
device to use or provide OF-based API such (devm_xxx).
