Change log level of few error messages to debug

:Release Notes:
Change the log level for few msgs to debug since they are not real errors.

:Detailed Notes:
The message reporting error for not finding nyx device led controller made
sense for devices like tablet, phones which require to suspend but is
not valid for TV since it doesnt use led controllers, so for now changing
the message level to debug. Later on this part of code needs to be changed
to make it generic enough to support TVs as well as other devices.
Similarly the message reporting error while initializing clock is misleading
since it takes a while for TV to update the system clock, so first time it
always fails, but eventually it gets it right.

:Testing Performed:
Verified these two messages are now logged at debug level.

:Issues Addressed:
[ANG-2] Error messages from Sleepd

sleepd

Summary

Open webOS component to manage device suspend-resume cycles.

Description

Sleepd is one of the important daemons started when webOS boots. It is responsible for scheduling platform sleeps as soon as it is idle, so that we see optimum battery performance. To achieve this it keeps polling on the system to see if any of the other services or processes need the platform running, and if not it sends the suspend message to all these components (so that they can finish whatever they are doing ASAP and suspend). Sleepd then lets the kernel know that the platform is ready to sleep. Once an interrupt (such as key press) has woken the platform up, sleepd lets the entire system know that the platform is up and running so that all the activities can resume.

Sleepd also manages the RTC alarms on the system by maintaining a SQlite database for all the requested alarms.

How to Build on Linux

Dependencies

Below are the tools and libraries (and their minimum versions) required to build sleepd:

  • cmake (version required by openwebos/cmake-modules-webos)
  • gcc 4.6.3
  • glib-2.0 2.32.1
  • libxml2 2.7.2
  • make (any version)
  • openwebos/cjson 1.8.0
  • openwebos/cmake-modules-webos 1.0.0 RC4
  • openwebos/luna-service2 3.0.0
  • openwebos/nyx-lib 2.0.0
  • openwebos/powerd 4.0.0
  • pkg-config 0.26
  • sqlite3 3.6.20

Building

Once you have downloaded the source, enter the following to build it (after changing into the directory under which it was downloaded):

$ mkdir BUILD
$ cd BUILD
$ cmake ..
$ make
$ sudo make install

The directory under which the files are installed defaults to /usr/local/webos. You can install them elsewhere by supplying a value for WEBOS_INSTALL_ROOT when invoking cmake. For example:

$ cmake -D WEBOS_INSTALL_ROOT:PATH=$HOME/projects/openwebos ..
$ make
$ make install

will install the files in subdirectories of $HOME/projects/openwebos.

Specifying WEBOS_INSTALL_ROOT also causes pkg-config to look in that tree first before searching the standard locations. You can specify additional directories to be searched prior to this one by setting the PKG_CONFIG_PATH environment variable.

If not specified, WEBOS_INSTALL_ROOT defaults to /usr/local/webos.

To configure for a debug build, enter:

$ cmake -D CMAKE_BUILD_TYPE:STRING=Debug ..

To see a list of the make targets that cmake has generated, enter:

$ make help

Uninstalling

From the directory where you originally ran make install, enter:

$ [sudo] make uninstall

You will need to use sudo if you did not specify WEBOS_INSTALL_ROOT.
