The initial driver had many textual and structural problems. I have added next patches to modify existing problems. There was concern about the design of keeping separate regmaps for each instance of the amplifier explicitly instead of instantiating two instances of a single, simpler driver. This was major change of this release. Coding style problem like indentation also have been fixed.

Ryan Lee (10): ALSA SoC MAX98927 driver - Initial release Updated max98927_reg table with physical defaults. Replaced max98927.h for better legibility Removed the secondary device initialization from the primary device initialization. Removed manual register configuration from devicetree Modified indentation Replaced pr_err by dev_err. Modified debug message Added mask variable to apply it in one round after the switch Modified initialization code of VI sensing Added DAI Sel Mux and minor updates Added ACPI support. Changed snd_kcontrol_chip to snd_soc_kcontrol_codec Added vendor prefix. Added range information

New subject: [alsa-devel] [PATCH 03/10] Removed the secondary device initialization from the primary device initialization. Removed manual register configuration from devicetree

Signed-off-by: Ryan Lee ryans.lee@maximintegrated.com --- Keeping seperate regmaps for each instance of the amplifier was not good idea. So this part has been removed. Manual register configuration from devicetree was also removed.
