From eef57324d926f0d8c7a40069e7d26e0cb0651b47 Mon Sep 17 00:00:00 2001 From: Jerome Anand Date: Wed, 25 Jan 2017 04:27:49 +0530 Subject: drm/i915: setup bridge for HDMI LPE audio driver Enable support for HDMI LPE audio mode on Baytrail and Cherrytrail when HDaudio controller is not detected Setup minimum required resources during i915_driver_load: 1. Create a platform device to share MMIO/IRQ resources 2. Make the platform device child of i915 device for runtime PM. 3. Create IRQ chip to forward HDMI LPE audio irqs. HDMI LPE audio driver (a standalone sound driver) probes the LPE audio device and creates a new sound card.

Also, while we're at it, tidy up the section title from all lower letters.
