The current devfreq_update_status() has the following bugs:
- If previous frequency doesn't have a valid level, it does an out of bounds

- When the new frequency doesn't have a valid level, the time spent in the

phy-core: phy_get: Leave error logging to the caller
In various cases errors may be expected, ie probe-deferral or a call to
phy_get from a driver where the use of a phy is optional.
Rather then adding all sort of complicated checks for this, and/or adding
special functions like devm_phy_get_optional, simply don't log an error,
and let deciding if get_phy returning an error really should result in a
dev_err up to the caller.

The common clock framework considers NULL a valid clock

optional clock is not available, a NULL reference can be used in the

Extend this concept to the phy consumer API. A NULL can be passed to

drm/panel: Add simple panel support
Add a driver for simple panels. Such panels can have a regulator that
provides the supply voltage and a separate GPIO to enable the panel.
Optionally the panels can have a backlight associated with them so it
can be enabled or disabled according to the panel's power management
mode.
Support is added for two panels: An AU Optronics 10.1" WSVGA and a
Chunghwa Picture Tubes 10.1" WXGA panel.

drm: Add panel support
Add a very simple framework to register and lookup panels. Panel drivers
can initialize a DRM panel and register it with the framework, allowing
them to be retrieved and used by display drivers. Currently only support
for DPMS and obtaining panel modes is provided. However it should be
sufficient to enable a large number of panels. The framework should also
be easily extensible to support more sophisticated kinds of panels such
as DSI.
The framework hasn't been tied into the DRM core, even though it should
be easily possible to do so if that's what we want. In the current
implementation, display drivers can simple make use of it to retrieve a
panel, obtain its modes and control its DPMS mode.
Note that this is currently only tested on systems that boot from a
device tree. No glue code has been written yet for systems that use
platform data, but it should be easy to add.
