[v2,0/3] Add SARADC support on Sophgo SoC

Message

Thomas Bonnefille July 5, 2024, 1:42 p.m. UTC

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 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/[e-mail]
