When using RCCLK instead of MCLK / PLL1 the OVCD status often gets stuck
at its last value, which breaks jack-type detection.
This commit fixes this by force-enabling the platform clock when doing
jack-type detection.

When the mic-gnd contacts are short-circuited by a headphones plug, the
hardware periodically retries if it can apply the bias-current leading to
the OVCD status flip-flopping 1-0-1 with it being 0 about 10% of the time.
This commit enables the sticky bit for the OVCD status to deal with this.
This commit also introduces 2 helper functions to deal with the OVCD
status bit, this may seem a bit overkill now, but these will also be
used in future patches.

OVer-Current-Detection (OVCD) for the micbias current is used to detect if
an inserted jack is a headset or headphones (mic shorted to ground).
The threshold for at which current the OVCD triggers on the rt5651 is not
only controlled by setting the absolute current limit, but also by setting
a scale factor which applies to the limit. Testing has shown that we need
to set both (depending on the board).
This commit adds support for the sofar unused OVCD scale-factor register
and adds support for specifying non-default values for it through the
"realtek,over-current-scale-factor" device-property.

OVer-Current-Detection (OVCD) for the micbias current is used to detect
if an inserted jack is a headset or headphones (mic shorted to ground).
Some boards may need different values for the OVCD current threshold
because of a resistor on the board in serial with or parallel to the
jack mic contact.
This commit adds support for configuring the OCVD current threshold
through the "realtek,over-current-threshold-microamp" device-property.
Note this commit changes the default value from 600uA to 2000uA,
because testing has shown 600uA to be a poor default.

The idea behind exporting rt5651_apply_properties(), was for it to be used
on platforms where the platform code may need to add device-properties,
rather then relying only on properties set by the firmware. The platform
code could then call rt5651_apply_properties() after adding properties to
make sure that the codec driver was aware of the new properties.
But this is not necessary, as long as we do all property parsing from
the codec component-driver's probe function (or later) then the machine
driver can attach properties before calling snd_soc_register_card and
calling rt5651_apply_properties() for ordering reasons is not necessary.
This commit makes rt5651_apply_properties() private and adds 2 comments
documenting that all property parsing must be done from the codec
component-driver's probe function.

To determine if a plugged in jack is a headset (speakers + mic) or
headphones (mic contact shorted to ground) we use the micbias1 OVer Current
Detect (OVCD) functionality.
For this to work we need to have a micbias current to actually cause an
overcurrent condition when headphones are plugged in, so jack-type
detection requires both the LDO and micbias1 supplies to be on.
Before this commit there were 2 issues with the handling of this:
1) The LDO supply was force-enabled twice and never disabled again even
though it only needs to be forced on when doing jack-type detection
2) micbias1 was not force-enabled, and thus may be off when doing jack-type
detection
This commit fixes both by force-enabling the LDO and micbias1 supplies
before checking for an overcurrent condition and disabling them afterwards.
Note that both supplies will still get turned on normally (and OVCD will
protect against overcurrent) when the micbias1 is enabled normally because
the user has activated a sound stream recording from the mic.

Remove the "JD power" dapm supply which gets force-enabled once when
using jack-detect and never gets disabled again.
Since the PWR_JD_M bit simply needs to be always on when using jack-detect
there is no need to have it tracked by dapm, instead we can simply set it
to 1 once when initializing the jack-detection.

The rt5651_set_bias_level() function was turning everything off at
SND_SOC_BIAS_STANDBY, rather then at SND_SOC_BIAS_OFF, requiring the bias-
level to be raised to SND_SOC_BIAS_PREPARE before turning anything on.
This is not how the bias-levels are supposed to work, this commit fixes
this by turning everything off at the SND_SOC_BIAS_OFF level and enabling
the pwr-bits needed for minimum functionality at SND_SOC_BIAS_STANDBY.
This fixes the minimum set of pwr-bits not getting enabled when
force-enabling some dapm-supplies (e.g. for jack type detection),
which raises the bias-level to standby.

is_sys_clk_from_pll() is used as a snd_soc_dapm_route.connected callback,
checking RT5651_GBL_CLK to determine if the sys-clk is PLL1 and thus the
PWR_PLL bit in reg PWR_ANLG2 must be set.
RT5651_GBL_CLK is changed by rt5651_set_dai_sysclk(), which gets called by
the pre_pmu / post_pmd functions of the "Platform Clock" dapm-supply.
This creates an ordering issue, during a dapm transition first all
connected() callbacks are called to build a list of supplies to enable
and then the complete list is walked to enable the supplies. Since the
connected() check happens before enabling any supplies,
is_sys_clk_from_pll() ends up deciding if the PWR_PLL bit should be set
based on the state the "Platform Clock" supply had *before* the transition.
This sometimes results in PWR_PLL being off, even though *after* the
transition PLL1 is configured as sys-clk.
This commit removes is_sys_clk_from_pll() instead simply setting / clearing
PWR_PLL in rt5651_set_dai_sysclk() based on the selected sys-clk, which
fixes this and as a bonus results in a nice cleanup.

Move all jack-detect initialization to rt5651_set_jack_detect. The main
reason to do this is so that platform code can setup jack-detect properties
after the device has been probed, which unfortunately is necessary on some
platforms.
This has 2 additional advantages:
1) Grouping all jack-detect init together makes it easier to follow what
is happening and results in a small reduction in the number of loc.
2) Before we would register the irq handler before rt5651->hp_jack was
assigned, leading to a potential NULL deref if the jack_detect work runs
before the machine driver has called set_jack.

important fixes in here, mainly a fix for I/O on a number of devices
caused by some of the component rework and a fix for a potential issue
if more than one component in a link provides compressed operations.
The I/O fixes are particularly important as the problem causes a power

Commit 3bb0f7c31b ("ASoC: don't use snd_soc_write/read on twl4030")
caused regressions for both twl4030 and twl6040 as it assumes the
ASoC driver is using regmap. As a side effect, this also causes a
considerable increase in idle power consumption omap3 boards using
twl4030 as the PMIC.
This is because the removal of read and write function pointers
causes some of the ASoC IO functions to not do anything. For example,
snd_soc_register_card() calls snd_soc_dapm_new_widgets() that calls
snd_soc_codec_drv_read() that now does nothing.
A long term solution suggested by Mark Brown <broonie@kernel.org>
is to make the twl drivers use regmap by adding a call to
snd_soc_codec_set_regmap(). This however needs more consideration
as currently the driver internal reads do caching and we would have
both regmap access and internal read/write access accessing the same
hardware registers.
So to fix the regression, let's just do a partial revert adding back
the read and write function pointers. Note that other non-regmap
ASoC drivers may need similar patches.

to specify the number of DMIC channels. dmic_codec_probe() uses
of_property_read_u32() to read the DT value, and expects a return

is incorrect, the actual value returned in this case is -EINVAL (see
of_find_property_value_of_size(), which is called under the hood).
Check for -EINVAL instead.
