Subject: [PATCH 0/2] drm/i915: initialize backlight pwm frequency from vbt if needed
Date: Tue, 7 Jan 2014 18:01:32 +0200 [thread overview]
Message-ID: <cover.1389109881.git.jani.nikula@intel.com> (raw)
Per inquiries from Vathsala et al, here's some early code for
initializing the backlight PWM from VBT if it hasn't been initialized by
the BIOS. I didn't have the chance to test this at all yet, just wanted
to unblock others. Testing and comments welcome. Particularly the
frequency in Hz to PWM register value conversions need eyeballs.
BR,
Jani.
