13248d66ae treewide: use linux/time.h for time conversion defines
Now that we have time conversion defines from in time.h there is no need
for each driver to define their own version.

846dcae733 video: tegra20: dsi: use regulator_set_enable_if_allowed
With the commit 4fcba5d556 ("regulator: implement basic reference
counter") the return value of regulator_set_enable may be EALREADY or
EBUSY for fixed/gpio regulators and may be further expanded on all
regulators.

Change to use the more relaxed regulator_set_enable_if_allowed to
continue if regulator already was enabled or disabled.

d8cca91380 video: tegra: add DC based PWM backlight driver
DC based PWM backlight is found on some T20 and T30 devices

is adjustable by the DC PM0 or PM1 signal.

acbb871af5 video: tegra20: add DSI controller driver
Adds support for both DSI outputs found on Tegra. Only very
minimal functionality is implemented, so advanced features
like ganged mode won't work. Driver is heavily based on
mainline Tegra DSI and re-uses much of its features.

Only T30 is supported for now but T20 support can be added
if any supported devices will be found.

Driver is wrapped as panel driver since Tegra DC driver supports
only panel drivers calls.

a8f4f9f815 video: tegra-dc: pass DC regmap to internal devices
Internal video devices like DSI and HDMI controllers
require sending commands into DC register field.
To make this available, lets create platform data,
which is restricted to pass DC regmap only to
pre-defined devices.

b450c6c7e3 video: tegra-dc: add panel_set_backlight call
Tegra DC driver does not call panel_set_backlight, which can
result in absence of backlight on device. Fix this by calling
panel_set_backlight with BACKLIGHT_DEFAULT just after
panel_enable_backlight.

8076cc51fb video: tegra-dc: add 180 degree panel rotation
Unlike 90 and 270 degree rotation, 180 degree rotation is more
common and does not require scaling. Implement it for correct
grouper support.

Check if panel driver has display timings and get those.
If panel driver does not pass timing, try to find timing
under rgb node for backwards compatibility.
