Internal clock of AD719X devices can be made available on MCLK2 pin. Add
clock provider to support this functionality when clock cells property
is present.
The clock source can be either provided externally or the internal clock
is used. Pair of clocks and clock-names property is mutally exclusive
with #clock-cells property.
Modify second example to showcase the mode where internal clock is used.

There are actually 4 configuration modes of clock source for AD719X
devices. Either a crystal can be attached externally between MCLK1 and
MCLK2 pins, or an external CMOS-compatible clock can drive the MCLK2
pin. The other 2 modes make use of the 4.92MHz internal clock.
Undocumented properties adi,int-clock-output-enable and adi,clock-xtal
still supported for backward compatibility, but their use is highly
discouraged. Use cleaner alternative of configuring external clock by
using clock names mclk and xtal.
Functionality of AD7192_CLK_INT_CO will be implemented in complementary
patch by adding clock provider.

pin. The other 2 modes make use of the 4.92MHz internal clock.
To configure external clock as either a crystal or a CMOS-compatible
clock, changing the register settings is necessary. Therefore, add clock
name xtal alongside mclk. By selecting one or the other, the register is
configured.
The presence of an external clock source is optional, not required. When
both clocks and clock-names properties are present, an external clock
source is used. If the intention is to use the internal clock, both
properties should be absent. Modify required properties accordingly.

This makes use of the new devm_regulator_get_enable_read_voltage()
helper function to reduce boilerplate code in the MCP3911 ADC driver.
The error message is slightly changed since there are fewer error
return paths.
An extra parameter is added to the config callback to avoid adding
state that is not used outside of the probe() function.

According to the datasheet, both pressure and temperature can go up to
oversampling x32. With this option, the maximum measurement time is not
80ms (this is for press x32 and temp x2), but it is 130ms nominal
(calculated from table 3.9.2) and since most of the maximum values
are around +15%, it is configured to 150ms.

This is a new driver for Analog Devices Inc. AD4695 and similar ADCs.
The initial driver supports initializing the chip including configuring
all possible LDO and reference voltage sources as well as any possible
voltage input channel wiring configuration.
Only the 4-wire SPI wiring mode where the CNV pin is tied to the CS pin
is supported at this time. And reading sample data from the ADC can only
be done in direct mode for now.
