This set of patches adds support for using the CS35L56 boosted smart amplifier on HDA systems. In these systems the CS35L56 audio is routed through a HDA-to-I2S bridge codec.
This doesn't include the changes to the Realtek driver to actually hook up the CS35L56 driver, because we don't yet have the QUIRK IDs to associate it with. But we want to publish the driver now so that it is available for bringing up hardware with the CS35L56.
The first 9 patches are moving code out of the ASoC driver and into the shared library so that it can be shared with the HDA driver.
Patch #10 fixes missing #includes in the HDA headers so that the CS35L56 driver doesn't have to #include headers that it doesn't use.
CHANGES SINCE V5 The series has been rebased onto commit df4167d658d4 ("ASoC: cs35l56: Patch soft registers to defaults"), which removes cs35l56_reread_firmware_registers() and adds cs35l56_set_patch().
Changes are trivial so I have carried forward Mark's and Takashi's acks.
Patch 01: - Also changes cs35l56_set_patch() argument to new struct cs35l56_base.
Patch 11: - Remove call to cs35l56_reread_firmware_registers() - Add call to cs35l56_set_patch() in cs35l56_hda_common_probe() - Do not add mute_hook to struct hda_component. This was for use with CS8409 as an HDA bridge, but production systems will use Realtek, which has its own mute control. - Use strscpy() instead of strcpy() in cs35l56_hda_mixer_info() - Fix missing word in Kconfig option title
