<pre>I already tested that in April and reported about it. Is there anything new
that I should test?
<a href="http://www.spinics.net/lists/intel-gfx/msg91730.html">http://www.spinics.net/lists/intel-gfx/msg91730.html</a>
The PWM devices are present and drivers loaded, as shown in:
<a href="http://www.spinics.net/lists/intel-gfx/msg92110.html">http://www.spinics.net/lists/intel-gfx/msg92110.html</a>
but they are not detected by i915. None of them is named "pwm-backlight", so I
guess that I miss something that would map the existing PWM to the name
"pwm-backligth", maybe like this line does for crystalcove:
<a href="http://lxr.free-electrons.com/source/drivers/mfd/intel_soc_pmic_core.c#L43">http://lxr.free-electrons.com/source/drivers/mfd/intel_soc_pmic_core.c#L43</a>
Is there anything that can map LPSS pwm to "pwm-backlight"? That's the piece I
could not find anywhere.</pre>
