HAB driver can parse its relevant entries from device
tree, and get necessary info, like its local vmid,
physical channel groups, and etc.

Changes to vote for camera clocks so as to maintain clock vote
when early camera transitions from LK to kernel.
Changes to vote off also included once early camera shuts down.

This new driver is meant to be a cross-platform abstraction
layer for utilizing the underlying hypervisor system.
This API can be accessed from both user and kernel sides.
The intended users of this are the multimedia drivers who want
to communicate with the host OS to use the multimedia hardware.

Based on the duration of the pattern, haptics mode and other
parameters needs to be configured dynamically for a better
performance and ease of use. Add support for this through device
tree property "qcom,lra-auto-mode".
Add support to configure some parameters like auto resonance
mode, LRA high-Z period, calibration period, vmax along with an
option to override the settings done by auto_mode configuration.

Currently MISC_TRIM_ERROR_RC19P2_CLK register is hardcoded to
read the trim error in 19.2 MHz RC clock. However, this can be
located differently in some PMICs. Add support to read it from
misc device as this register cannot be directly accessed from
haptics driver.
Specify the MISC peripheral and the clock trim error register in
haptics for pmi8998 and pm660 so that haptics initial drive code
can be adjusted based on error code properly.

While calculating the +/-30% variation from the resonant frequency for auto
resonance search algorithm, division by zero is happening causing device
crash. Add additional checks to avoid such crashes. Also, RATE_CFG1 and
RATE_CFG2 registers should be updated with values from AUTO_RES_LO and
AUTO_RES_HI registers respectively only if the frequency variation is
+/-25% of the resonant freqeuncy. Add code change for the same.

For auto resonance detection to work properly, sufficient
back-emf has to be generated. In general, back-emf takes
some time to build up. When the auto resonance mode is chosen
as QWD, high-z will be applied for every LRA cycle and hence
there won't be enough back-emf at the start-up. Hence, the
motor needs to vibrate for few LRA cycles after the PLAY bit
is asserted. So disable the auto resonance and enable it back
after some delay. Add DT property to configure this delay value.

DCC (Data Capture and Compare) is a DMA engine which is used to save
configuration data or system memory contents during catastrophic failure
or SW trigger.
It can also perform CRC over the same configuration or memory space.
