ee1a4d4b7f ASoC: Tegra: wm8903 machine driver: Drop Ventana support
Board file support for Ventana is not yet mainlined, and probably won't
ever be given the move to Device-Tree. Consequently, the Ventana entry
is being removed from arch/arm/tools/mach-types in the next merge window,
since it was registered over a year ago.

This will also remove function machine_is_ventana(), which is used by
the ASoC Tegra WM8903 machine driver. This will cause compilation
failures. Drop Ventana support to resolve this.

Hopefully, in the not-too-distant future, tegra_wm8903.c will be able to
configure itself from Device-Tree, and hence we'll be able to re-instate
Ventana support just by creating a .dts file for the board.

Also note that Aebl support is in a similar boat. However, that board
isn't scheduled for deprecation for at least another 5 months, and
perhaps we will have completely removed non-Device-Tree support from
tegra_wm8903.c by then and/or adjusted mach-types policy.

29591ed4ac ASoC: Tegra: wm8903 machine driver: Allow re-insertion of module
Two issues were preventing module snd-soc-tegra-wm8903.ko from being
removed and re-inserted:

a) The speaker-enable GPIO is hosted by the WM8903 chip. This GPIO must
   be freed before snd_soc_unregister_card() is called, because that
   triggers wm8903.c:wm8903_remove(), which calls gpiochip_remove(), which
   then fails if any of the GPIOs are in use. To solve this, free all GPIOs
   first, so the code doesn't care where they come from.

b) We need to call snd_soc_jack_free_gpios() to match the call to
   snd_soc_jack_add_gpios() during initialization. Without this, the
   call to snd_soc_jack_add_gpios() fails during any subsequent modprobe
   and initialization, since the GPIO and IRQ are already registered. In
   turn, this causes the headphone state not to be monitored, so the
   headphone is assumed not to be plugged in, and the audio path to it is
   never enabled.

a5fe6be42e ASoC: Tegra: Enable Kaen HP_MUTE at boot
We want the default state of the HP_MUTE signal to be asserted, so that
the headphones are muted before the first audio playback. Without this,
the headphones are left unmuted until shortly after the first audio
playback completes.

dea8b6eef0 ASoC: Tegra: wm8903: s/code/data/ for control/widget/maps
Replace calls to a variety of registration functions by updating
struct snd_soc_card snd_soc_tegra_wm8903 to directly point at the
various control/widget/map tables instead. The ASoC core now
performs any required registration based on these data fields.

a32955dba2 ASoC: Tegra: Retrieve card from DAPM context not codec
Card widgets are created in the card's DAPM context, not any codec's DAPM
context. Hence, w->codec==NULL. Instead, find the card from the widget
through the DAPM context of the widget, not the codec of the widget.

075413966a ASoC: Tegra: Don't return mclk_changed from utils_set_rate
Only the clock programming code needs to know whether the clocks changed,
and that is encapsulated within tegra_asoc_utils_set_rate(). The machine
driver's call to snd_soc_dai_set_sysclk(codec_dai, ...) is safe
irrespective of whether the clocks changed.

acb8303f15 ASoC: Tegra: wm8903: Remove redundant drvdata clears
When the driver is not initialized/registered, nothing should be touching
these fields anyway, so there's no point clearing them out.

d9e3c4cc68 ASoC: Tegra: wm8903 probe: Don't call machine_is_*()
This machine driver is a platform driver, and hence will only be
instantiated on the correct machines. Hence, there is no need to
check the current machine during probe.

773b1d3d31 ASoC: Tegra: Support more boards
* Ventana is identical to Harmony.
* Seaboard, Kaen, and Aebl are all pretty similar, mainly with slightly
  different sets of GPIOs, and slightly different WM8903 pin connectivity.

3eb25f998d ASoC: Tegra: Don't store snd_soc_jack_gpio in an array
Storing the struct in an array makes the assignments to the GPIO member a
little non-obvious, and is pointless when there's only a single GPIO.

(I thought I fixed this during the review cycle when first submitting this
driver, but I guess I overlooked that)

dc0a50afa6 ASoC: Tegra: Rename harmony.c to tegra_wm8903.c
Soon, this machine driver will be updated to handle a number of Tegra boards
using the WM8903 codec. Rename the file in advance to reflect this.

Fix the content of tegra_wm8903.c to match the rename; replace references
to Harmony board with something more generic.

* s/struct tegra_harmony/struct tegra_wm8903/
* s/harmony/machine/ # variable name
* Similar rename for some functions
* Similar comment fix
* Similar MODULE_DESCRIPTION fix
