Liu Ying 8c16f3303c backlight: update backlight status when necessary
We don't have to update a backlight status every time a blanking or
unblanking event comes because the backlight status may have already
been what we want.  Another thought is that one backlight device may be
shared by multiple framebuffers.  We don't hope blanking one of the
framebuffers may turn the backlight off for all the other framebuffers,
since they are likely being active to display something.

This patch makes the backlight status be updated only when the relevant
backlight device's use count changes from zero to one or from one to
zero.

Liu Ying a55944ca82 backlight: update bd state & fb_blank properties when necessary
We don't have to update the state and fb_blank properties of a backlight
device every time a blanking or unblanking event comes because they may
have already been what we want.  Another thought is that one backlight
device may be shared by multiple framebuffers.  The backlight driver
should take the backlight device as a resource shared by all the
associated framebuffers.

This patch adds some logic to record each framebuffer's backlight usage
to determine the backlight device use count and whether the two
properties should be updated or not.  To be more specific, only one
unblank operation on a certain blanked framebuffer may increase the
backlight device's use count by one, while one blank operation on a
certain unblanked framebuffer may decrease the use count by one, because
the userspace is likely to unblank an unblanked framebuffer or blank a
blanked framebuffer.

Sean Paul 2e4e678aa8 drm/exynos: Move dp driver from video/ to drm/
This patch moves the code from video/ to drm/. This is required the DP
driver needs to power on/off in the correct order in relation to fimd.
This will also allow the DP driver to participate in drm modeset as well
as provide accurate connection detection and edid.

Jean Delvare f167a64e9d video / output: Drop display output class support
It was only ever used by the ACPI video driver, and that only use case
vanished over 3 years ago (see commit 677bd810, "ACPI video: remove
output switching control".) So this is dead code and I guess we can
remove it now.

Tomi Valkeinen 6274a61978 OMAPDSS: Add DT support to DSI
Add the code to make the DSI driver work with device tree on OMAP3 and
OMAP4.

A minor hack is needed at the moment in the DSI driver: the DSS driver
needs to know the ID number of a DSI device, as clocks are routed in
different ways to the DSI devices. At the moment we don't have any
proper way to manage this, so this patchs adds a simple lookup table
that is used to deduce the ID from the DSI device's base address.

Tomi Valkeinen 2ecef24630 OMAPDSS: Add DT support to DSS
Add DT support for DSS. Contrary to the non-DT version, the DSS in DT
mode contains DPI and SDI outputs, which better reflects the hardware.
The non-DT code will be removed after all boards have been converted to
DT, so there's no need to change the non-DT code to act the same way.

The code for DPI and SDI needs to be refined later to make it possible
to add multiple DPI ports. For now, handling just a single DPI port is
enough for all the boards.

Tomi Valkeinen e6fa68ba82 OMAPDSS: Improve regulator names for DT
The regulator names used for DSS components are somewhat ugly for DT
use. As we're just adding DT support, it's simple to change the
regulator names.

This patch makes the DSS driver get the regulators with somewhat cleaner
names when bootin with DT. For example, this allows us to define HDMI's
VDDA regulator in the DT data as:

vdda-supply = <...>;

instead of

vdda_hdmi_dac-supply = <...>;

This is a temporary solution until we get generic code to parse the

Tomi Valkeinen 3e22b35534 OMAPDSS: get dssdev->alias from DT alias
We currently create a "displayX" style alias name for all displays,
using a number that is incremented for each registered display. With the
new DSS device model there is no clear order in which the displays are
registered, and thus the numbering is somewhat random.

This patch improves the behavior for DT case so that if the displays
have been assigned DT aliases, those aliases will be used as DSS
aliases.

This means that "display0" is always the one specified in the DT alias,
and thus display0 can be used as default display in case the user didn't
specify a default display.
