Please add the code name of the specific chip product to the
patch/commit/email title for easy distinguish.
Sophgo has several product series, not just cv18xx, for example, sg2042
etc, and there may be others in the future.
You can refer to this example [1]

This patchset adds initial ADC support for Sophgo SoC. This driver can
work with or without interrupt and in "Active" and "No-Die" domains
depending on if a clock is provided.

Changes in v3:
- Subdivide default cycle configuration into multiple elementary
configurations
- Fix formatting in the driver
- Use devm_mutex_init
- Use devm_clk_get_enabled now because the clock is no more optional
- Remove handling of Saradc in No-Die Domain as RTC isn't implemented yet
- Use cv1800-saradc as default compatible instead of a wildcard
- Link to v2: https://lore.kernel.org/r/20240705-sg2002-adc-v2-0-83428c20a9b2@xxxxxxxxxxx
Changes in v2:
- Drop modifications in MAINTAINERS file
- Rename the ADC from "sophgo-adc" to "sophgo-cv18xx-adc" to avoid
conflict with ADCs available in future Sophgo SoCs.
- Reorder nodes in DT to match DTS coding style
- Switch from including <linux/of.h> to <linux/mod_devicetable.h>
- Use scoped_guard instead of mutex_lock/unlock
- Check IRQ Status in the handler
- Change IIO device name
- Use devm_clk_get_optional_enabled instead of a clock variable
- Init completion before the IRQ request
- Removed unnecessary iio_info structure in the private data of the
driver
- Use SoC specific compatible in the bindings and device trees
- Link to v1: https://lore.kernel.org/r/20240702-sg2002-adc-v1-0-ac66e076a756@xxxxxxxxxxx
