ALSA: hda - Move hda_i915.c from sound/pci/hda to sound/hda

2015-05-20T04:16:36+00:00

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.

ALSA: hda - Add the controller helper codes to hda-core module

2015-04-16T05:27:58+00:00

This patch adds the controller helper codes to hda-core library. The I/O access ops are added to the bus ops. The CORB/RIRB, the basic attributes like irq# and iomap address, some locks and the list of streams are added to the bus object, together with the stream object and its helpers. Currently the codes are just copied from the legacy driver, so you can find duplicated codes in both directories. Only constants are removed from the original hda_controller.h. More integration work will follow in the later patches. Signed-off-by: Takashi Iwai
