Mstar driver uses the ic-type DT property for dynamic detection
support. Driver reads a register from the controller and compares
both the values to check if connected touch controller is of
Mstar or not.
Remove all DBG messages and convert them to dev_dbg/info.
Add a debugfs entry for suspend/resume.
Remove ts_data/pdata global declaration and use dev_get_drvdata()
and input_set_drvdata()/dev_set_drvdata() instead.

WCD audio codecs contain SPI slave hardware module to provide access

slave hardware. This driver uses regmap for SPI internal register
accesses and plugs in to standard SPI framework as child device to

WCD audio codecs have DSP embedded to perform signal processing on
audio data. The codec driver has control over the DSP clock, power etc,
whereas the DSP memory can be accessed through an different bus slave
interface. In such cases, it is required to make sure the hardware
expected sequences are met for the DSP to function properly. The
wcd-dsp manager driver registers as master to component framework
and provides the ability to sequence the operations between the child
drivers. Upon registration of all children, the wcd-dsp manager driver
parses the wcd dsp image, downloads the image and boots up the DSP.
It invokes the component children to perform the tasks in sequence.

A check is needed to ensure the LSB and MSB are coherent
when reading the result registers for the RRADC channels.
The driver performs another round of read request and
compares the result registers to ensure the data read
back is coherent.
Since there are no channel specific properties remove
the dependency to add the channel nodes in the device
tree and instead statically register the channels within
the driver.
Update the scaling functions to report in the units
desired for the final scaled value based on the channel.
The resistance channel reports the units for batt_id
in ohms, the voltage channels such as DCIN, USBIN report
the value in units of microvolts, the current channels
in units of microamps and the temperature channels
such as thermistors are reported in units of millidegC.
