From 98d8fc6c5d3652e91c61d78941e0fa6f94771d67 Mon Sep 17 00:00:00 2001 From: Mengdong Lin Date: Tue, 19 May 2015 22:29:30 +0800 Subject: ALSA: hda - Move hda_i915.c from sound/pci/hda to sound/hda The file is moved to hda core and renamed to hdac_i915.c, so can be used by both legacy HDA driver and new Skylake audio driver. - Add snd_hdac_ prefix to the public APIs. - The i915 audio component is moved to core bus and dynamically allocated. - A static pointer hdac_acomp is used to help bind/unbind callbacks to get this component, because the sound card's private_data is used by the azx chip pointer, which is a legacy structure. It could be removed if private _data changes to some core structure which can be extended to find the bus. - snd_hdac_get_display_clk() is added to get the display core clock for HSW/BDW. - haswell_set_bclk() is moved to hda_intel.c because it needs to write the controller registers EM4/EM5, and only legacy HD-A needs it for HSW/BDW. - Move definition of HSW/BDW-specific registers EM4/EM5 to hda_register.h and rename them to HSW_EM4/HSW_EM5, because other HD-A controllers have different layout for the extended mode registers.
