Andre Guedes 7c956d2ece drivers: Replace DEV_FAIL by -EIO
This patch replaces all occurences of the macro DEV_FAIL by -EIO
at the driver level. So this patch touch the files under drivers/,
include/ and samples/drivers/ when applicable.

This patch is part of the effort to transition from DEV_* codes to
errno.h codes.

Dan Kalowsky e97507a034 adc: dw: there is only one ADC
The ADC for DesignWare is currently setup to handle multiple dev entries,
but there only ever exists one.  No reason to add to complexity for multiple
if there is only going to be one.

Juan Manuel Cruz 21b5da27ff adc: fixes unexpected error with interrupt handler
Interrupt handler needs to finish all the handler work before
returning to the sync call.
Before this fix, a call to the API read() method could unexpectedly
fail because a second read() call could start before the previous
read() call had not completely finished.

Juan Manuel Cruz ff8138595e adc: adjustments to dummy read
Per Curie documentation, the first sample from the Quark SE ADC
hardware after reset needs to be dropped.
This commits changes the location and the trigger event to do
a dummy read that drops the first sample.
Originally the driver did the dummy read on the API call enable()
and it was triggered if the ADC had awakened from suspend mode.
Because the SoC is not in suspend mode on power on and the API
enable() call has no information on the channels to be read the
dummy read could be missed.
Now the dummy read is done on the API call to read()
and triggered if it is the first time read() is called
since power on.

Juan Manuel Cruz 41771e5b1c adc: Repetitive buffer management
This commit changes the behavior of the driver when it reports
buffer results back through the callback.

Originally, the driver reported a callback after each sequence
table round signaled by an interrupt. If in repetitive mode,
each reported result was put in the next buffer element,
which was considered circular, and reported back with callback.

Now the behavior changes. If in repetitive mode, each sequence table
round reported by an interruption puts the data  in next element of
the reception buffer. The callback reports back once the buffer is
fulled and stops the sampling process.

Curie specs states that the ADC_PWR_MODE_STS bit in the
IO_CREG_SLV0_OBSR register must be polled to check if
the requested power mode equals the current power mode.
The bit is set to 1 when requested and current modes match
and the bit is located as the bit 0.

Andrew Boie d9cfbd5a61 interrupts: new static IRQ API
The interrupt API has been redesigned:

- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
  It will be used in situations where the new static irq_connect()
  won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
  exactly the same way as its dynamic counterpart. The old static irq
  macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
  generated inline with irq_connect()

ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.

Juan Manuel Cruz 42696ca14f adc: simplifies buffer management on adc dw driver.
Buffer management on dw driver was too complex.
New buffer management follows the following behavior.
- Each sequence entry have one sample at a time.
- Each sequence entry have a buffer to store that sample.
- If ADC have repetitive sampling configuration, the buffer value
  is overwritten with the new value.

New buffer management allow us to remove Synposys'
files and license headers as well.
