3e1c0b9501 iio: frequency: adf4377: use dev_err_probe()
Use dev_err_probe() consistently in the probe path to simplify error
handling and ensure deferred probes are logged correctly.

b2d2a6ea12 iio: frequency: adf4377: add dev variable
Introduce a local struct device pointer in functions that reference
&spi->dev for device-managed resource calls and device property reads,
improving code readability.

6c8bf4b604 iio: frequency: adf4377: Fix duplicated soft reset mask
The regmap_read_poll_timeout() uses ADF4377_0000_SOFT_RESET_R_MSK
twice instead of checking both SOFT_RESET_MSK (bit 0) and
SOFT_RESET_R_MSK (bit 7). This causes an incomplete reset status check.

The code first sets both SOFT_RESET and SOFT_RESET_R bits to 1 via
regmap_update_bits(), then polls for them to be cleared. Since we set
both bits before polling, we should be waiting for both to clear.

Fix by using both masks as done in regmap_update_bits() above.

60e5448ddb iio: frequency: adf4377: add clk provider support
Add clk provider feature for the adf4377.

Even though the driver was sent as an IIO driver in most cases the
device is actually seen as a clock provider.

This patch aims to cover actual usecases requested by users in order to
completely control the output frequencies from userspace.

70788d26ae iio: normalize array sentinel style
Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace
the array sentinel in all IIO drivers to the same style.

For some time, we've been trying to consistently use `{ }` (no trailing
comma, no comment, one space between braces) for array sentinels in the
IIO subsystem. Still nearly 50% of existing code uses a different style.
To save reviewers from having to request this trivial change as
frequently, let's normalize the style in all existing IIO drivers.
At least when code is copy/pasted to new drivers, the style will be
consistent.

5f60d5f6bb move asm/unaligned.h to linux/unaligned.h
asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

auto-generated by the following:

for i in `git grep -l -w asm/unaligned.h`; do
	sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i

6140a92cd0 iio: frequency: adf4377: add adf4378 support
Add separate handling for adf4378 within the driver.

The main difference between adf4377 and adf4378 is that adf4378 has only
one output which is handled by only one gpio.

eda549e2e5 iio: frequency: adf4377: add support for ADF4377
The ADF4377 is a high performance, ultralow jitter, dual output integer-N
phased locked loop (PLL) with integrated voltage controlled oscillator
(VCO) ideally suited for data converter and mixed signal front end (MxFE)
clock applications.
