ALSA: hda - Make snd_hda_bus_type public Define the common hd-audio driver and device types to bind over snd_hda_bus_type publicly. This allows to implement other type of device and driver code over hd-audio bus. Now both struct hda_codec and struct hda_codec_driver inherit these new struct hdac_device and struct hdac_driver, respectively. The bus registration is done in subsys_initcall() to assure it before any other driver registrations. Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Add the controller helper codes to hda-core module 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 <tiwai@suse.de>

ALSA: hda - Move some codes up to hdac_bus struct A few basic codes for communicating over HD-audio bus are moved to struct hdac_bus now. It has only command and get_response ops in addition to the unsolicited event handling. Note that the codec-side tracing support is disabled temporarily during this transition due to the code shuffling. It will be re-enabled later once when all pieces are settled down.

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.

ALSA: hda - Add widget sysfs tree This patch changes the sysfs files assigned to the codec device on the bus which were formerly identical with hwdep sysfs files. Now it shows only a few core parameter, vendor_id, subsystem_id, revision_id, afg, mfg, vendor_name and chip_name. In addition, now a widget tree is added to the bus device sysfs directory for showing the widget topology and attributes. It's just a flat tree consisting of subdirectories named as the widget NID including various attributes like widget capability bits. The AFG (usually NID 0x01) is always found there, and it contains always amp_in_caps, amp_out_caps and power_caps files. Each of these attributes show a single value. The rest are the widget nodes belonging to that AFG. Note that the child node might not start from 0x02 but from another value like 0x0a. Each child node may contain caps, pin_caps, amp_in_caps, amp_out_caps, power_caps and connections files. The caps (representing the widget capability bits) always contain a value. The rest may contain value(s) if the attribute exists on the node. Only connections file show multiple values while other attributes have zero or one single value.

ALSA: hda - Add hduadio support to DEVTABLE For generating modalias entries automatically, move the definition of struct hda_device_id to linux/mod_devicetable.h and add the handling of this record in file2alias helper. The new modalias is represented with combination of vendor id, device id, and api version as "hdaudio:vNrNaN". This patch itself doesn't convert the existing modaliases.

ALSA: hda - Add regmap support This patch adds an infrastructure to support regmap-based verb accesses. Because o the asymmetric nature of HD-audio verbs, especially the amp verbs, we need to translate the verbs as a sort of pseudo registers to be mapped uniquely in regmap. In this patch, a pseudo register is built from the NID, the AC_VERB_GET_* and 8bit parameters, i.e. almost in the form to be sent to HD-audio bus but without codec address field. OTOH, for writing, the same pseudo register is translated to AC_VERB_SET_* automatically. The AC_VERB_SET_AMP_* verb is re-encoded from the corresponding AC_VERB_GET_AMP_* verb and parameter at writing. Some verbs has a single command for read but multiple for writes. A write for such a verb is split automatically to multiple verbs. The patch provides also a few handy helper functions. They are designed to be accessible even without regmap. When no regmap is set up (e.g. before the codec device instantiation), the direct hardware access is used. Also, it tries to avoid the unnecessary power-up. The power up/down sequence is performed only on demand. The codec driver needs to call snd_hdac_regmap_exit() and snd_hdac_regmap_exit() at probe and remove if it wants the regmap access. There is one flag added to hdac_device. When the flag lazy_cache is set, regmap helper ignores a write for a suspended device and returns as if it was actually written. It reduces the hardware access pretty much, e.g. when adjusting the mixer volume while in idle. This assumes that the driver will sync the cache later at resume properly, so use it carefully.

ALSA: hda - Use regmap for parameter caches, too The amp hash table was used for recording the cached reads of some capability values like pin caps or amp caps. Now all these are moved to regmap as well. One addition to the regmap helper is codec->caps_overwriting flag. This is set in snd_hdac_override_parm(), and the regmap helper accepts any register while this flag is set, so that it can overwrite even the read-only verb like AC_VERB_PARAMETERS. The flag is cleared immediately in snd_hdac_override_parm(), as it's a once-off flag. Along with these changes, the no longer needed amp hash and relevant fields are removed from hda_codec struct now. Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Use regmap for parameter caches, too The amp hash table was used for recording the cached reads of some capability values like pin caps or amp caps. Now all these are moved to regmap as well. One addition to the regmap helper is codec->caps_overwriting flag. This is set in snd_hdac_override_parm(), and the regmap helper accepts any register while this flag is set, so that it can overwrite even the read-only verb like AC_VERB_PARAMETERS. The flag is cleared immediately in snd_hdac_override_parm(), as it's a once-off flag. Along with these changes, the no longer needed amp hash and relevant fields are removed from hda_codec struct now. Signed-off-by: Takashi Iwai <tiwai@suse.de>

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 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 <tiwai@suse.de>

ALSA: hdac: Add snd_hdac_get_hdac_stream() Add a helper to find the stream using stream tag and direction. This is useful for drivers to query stream based on stream tag and direction, fox example while downloading FW thru DSP loader code Signed-off-by: Jeeja KP <jeeja.kp@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

ALSA: hda - Make snd_hda_bus_type public Define the common hd-audio driver and device types to bind over snd_hda_bus_type publicly. This allows to implement other type of device and driver code over hd-audio bus. Now both struct hda_codec and struct hda_codec_driver inherit these new struct hdac_device and struct hdac_driver, respectively. The bus registration is done in subsys_initcall() to assure it before any other driver registrations. Signed-off-by: Takashi Iwai <tiwai@suse.de>
