This combines the ad2s1210_update_frequency_control_word() and
ad2s1210_soft_reset() functions into a single function since they
both have to be called together. (The software reset does not reset
any configuration registers, it only updates the excitation output

- move AD2S1210_DEF_EXCIT macro with similar macros

staging: iio: resolver: ad2s1210: use regmap for config registers
This makes use of the regmap API to read and write the configuration
registers. This simplifies code quite a bit and makes it safer
(previously, it was easy to write a bad value to the config registers
which causes the chip to lock up and need to be reset).
This chip has multiple modes of operation. In normal mode, we do not use
regmap since there is no addressing - data is just bitshifted out during
the SPI read. In config mode, we use regmap since it requires writing
the address (with read/write flag) before reading and writing.
We don't use the lock provided by the regmap because we need to also
synchronize with the normal mode SPI reads and with the various GPIOs.
There is also a quirk when reading registers (other than the fault
register). If the address/data bit is set in the value read, then it
indicates there is a configuration parity error and the data is not
valid. Previously, this was checked in a few places, but not
consistently. Now, we always check it in the regmap read function.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

To improve here there is a quest to make the remove callback return

iio: addac: ad74413r: update channel function set
According to the datasheet switching to a new channel function implies
multiple steps.
All functions must be selected for a minimum of 130 μs before changing
to another function.
The DAC_CODEx registers are not reset by changing channel functions.
Prior to changing channel functions, it is recommended to set the DAC
code to 0x0000 via the DAC_CODEx registers. Set the channel function
to high impedance via the CH_FUNC_SETUPx registers before transitioning
to the new channel function. After the new channel function is configured,
it is recommended to wait 150 μs before updating the DAC code.
Even though the channel switch is done at only at probe, where a device
reset is performed, that does not guarantee that the steps prior
changing to new channel function should be neglected.
