Dave Airlie 0c6287ec12 drm/panel: Changes for v3.17-rc1
Panels can now be more finely controlled via .prepare() and .unprepare()
 callbacks in addition to .enable() and .disable(). New kerneldoc details
 what they are supposed to do and when they should be called.
 
 The simple panel driver gained support for a couple of new panels and it
 is now possible to specify additional delays during power up and power
 down sequences if panels require it.
 
 DSI devices can now advertise that they support non-continuous clock
 mode which will allow DSI host controllers to disable the high speed
 clock after transmissions to save power.

drm/panel: Changes for v3.17-rc1

Panels can now be more finely controlled via .prepare() and .unprepare()
callbacks in addition to .enable() and .disable(). New kerneldoc details
what they are supposed to do and when they should be called.

The simple panel driver gained support for a couple of new panels and it
is now possible to specify additional delays during power up and power
down sequences if panels require it.

DSI devices can now advertise that they support non-continuous clock
mode which will allow DSI host controllers to disable the high speed
clock after transmissions to save power.

Sjoerd Simons bd024b86f1 Subject: Revert "drm/exynos: remove MODULE_DEVICE_TABLE definitions"
This reverts commit d089621896 was
original to prevent multiple MODULE_DEVICE_TABLE in one module.
Which, as a side-effect broke autoloading of the module.

Since 21bdd17b21 it is possible to have
multiple calls to MODULE_DEVICE_TABLE, so the patch can be
reverted to restore support for autoloading

Inki Dae df5225bc9a drm/exynos: consider deferred probe case
This patch makes sure that exynos drm framework handles deferred
probe case correctly.

Sub drivers could be probed before resources, clock, regulator,
phy or panel, are ready for them so we should make sure that exynos
drm core waits until all resources are ready and sub drivers are
probed correctly.

Chagelog v2:
- Make sure that exynos drm core tries to bind sub drivers only in case that
  they have a pair: crtc and encoder/connector components should be a pair.
- Remove unnecessary patch:
  drm/exynos: mipi-dsi: consider panel driver-deferred probe
- Return error type correctly.

Andrew Bresticker b8b52471e8 drm/exynos: dp: support hotplug detection via GPIO
Certain bridge chips use a GPIO to indicate the cable status instead
of the I_DP_HPD pin.  This adds an optional device-tree property,
"samsung,hpd-gpio", to the exynos-dp controller which indicates that
the specified GPIO should be used for hotplug detection.
The GPIO is then set up as an edge-triggered interrupt where the
rising edge indicates hotplug-in and the falling edge indicates hotplug-out.

Many drm connectors do not need mode validation.

- imx move to a shared (but still dummy) ->mode_valid implementation.
- probe helpers have been extracted to drm_probe_helper.c
