This part of bias settings are essential for WM8962 to power up. Without it
"wm8962 0-001a: DC servo timed out" might be prompted due to power-up failure
that happens to FLL if being used.
The driver's also bringing the bias down in the suspend path so it needs to be
powered up in the resume path for symmetry.
According to dapm_pre_sequence_async(), DAPM would call pm_runtime_get_sync()
to let driver finish the bias settings in pm_runtime_resume() before the bias
level being set to STANDBY. So no need to worry about disordered settings for
VMID of WM8962.

Modify the RT5640 driver to parse platform data from device tree. Write
a DT binding document to describe those properties.
Slight re-ordering of rt5640_i2c_probe() to better fit the DT parsing.
Since ldo1_en is optional, guard usage of it with gpio_is_valid(), rather
than open-coding an if (gpio) check.

This driver is useless if both SPI and I2C are not configured.
Thus don't build this driver if both SPI and I2C are not configured.

Some runtime-determined constraints might need to be satisfied prior to
firmware loading, so the actual download and releasing the device from
reset has to be postponed. Factor it out first, so we have everything at
one place.
This also changes the behaviour in a way that adau1701_i2c_probe() will
assert the reset line, and wait for the codec probe to release it.

On a mx6qsabrelite board the following error happens on probe:
sgtl5000: probe of 0-000a failed with error -5
imx-sgtl5000 sound.13: ASoC: CODEC (null) not registered
imx-sgtl5000 sound.13: snd_soc_register_card failed (-517)
platform sound.13: Driver imx-sgtl5000 requests probe defer
Prior to reading the codec ID we need to turn the SYS_MCLK clock, so let's
enable the codec clock inside sgtl5000_i2c_probe().
Also remove the codec clock enable/disable functions from the machine driver.

When calling snd_soc_dapm_sync(), it eventually tries to lock the same mutex
already locked in snd_soc_dapm_put_volsw_aic3x() and a deadlock occurs. By
moving the mutex unlock to just before snd_soc_dapm_sync(), this deadlock is
prevented. This problem was introduced in Linux 3.5

to support HDMI on CSR SiRFprimaII and atlasVI, we need one more HDMI pseudo
codec, rather than add a new driver, we can make omap HDMI codec common for
other SoCs as well. then the omap-hdmi codec becomes a generic HDMI pseudo-
codec as HDMI audio features depend on HDMI specification not on SoCs.

The VAG_POWER must be enabled after all other bits in CHIP_ANA_POWER
and disabled before any other bit in CHIP_ANA_POWER. See the SGTL5000
datasheet (Table 31, BIT 7, page 42-43). Failing to follow this order
will result in ugly loud "POP" noise at the end of playback.
To achieve such order, use the _PRE and _POST DAPM widgets to trigger
the power_vag_event, where the event type check has to be fixed
accordingly as well.
