Currently, 0 is written into SWR_PLAY register when disabling SWR play,
it coincidently updates the PLAY_SRC to FIFO mode and disables it. If
there is a FIFO play triggered from SPMI address space, the FIFO play
will be disabled and the FIFO samples will be flushed. To avoid this,
keep in SWR PLAY_SRC when disabling SWR play.

Handle VMAX_CLAMP notification which is notified from charger driver
that hBoost is used by the charger firmware and haptics Vmax need to
be clamped to a specific level for the following vibrations.

After ADSP SSR happened, toggle swr_slave_vdd before play to reset
haptics HW so that it can function properly.

Haptics module is supplied by HBoost regulator by default, it requests
voltage to HBoost regulator through hardware channel. Haptics module
can also be configured to use other regulator device, in this case, it
requires software to request the voltage from the regulator before
enabling the play. Add support for this.

Update the slave-vdd regulator control logic to avoid unbalanced
regulator_enable() regulator_disable() calls. Meanwhile, correct
the jump label when bailing out from soundwire enumeration failure.
This helps to avoid the regulator_put() call in the device remove
process throwing a warning for a dangling regulator enable status.

Remove disable regulator during system suspend to avoid soundwire
interrupt during system suspend. This change will ensure that
device enter into power collapse during VoLTE usecase in LPI mode.

Per HW recommendation, when stopping SWR playing, SWR_PLAY register need
to get deasserted before disconnecting SWR data channel. Hence adjust the
sequence.

The haptics module in some PMICs has SWR slave data port which connects
to Bolero SWR RX port and it can receive PCM data from that port and use
it as the pattern source to play the vibration. Add the driver to
support it.
