[PATCH v4 0/4] iio: proximity: Add interrupt support for RFD77402
From: Shrikant Raskar via B4 Relay
Date: Thu Jan 01 2026 - 11:19:04 EST
This patch series adds:
- Add RF Digital vendor prefix
- YAML binding for RFD77402
- Add OF device ID for enumeration via DT
- Use kernel helper for result polling
- Interrupt handling support
These changes enable DT-based configuration and event-driven
operation for the RFD77402 Time-of-Flight sensor.
Changelog:
- Resend the patch series as v4 since not all patches were delivered
in v3 due to SMTP daily sending limits.
- Add 'Reviewed-by' tag to dt-binding patch.
- Update commit message in OF device ID patch.
- Update commit message in the third patch.
- Replace rfd77402_result_polling() with read_poll_timeout().
- Add 'struct rfd77402_data' details in kernel-doc format.
- Arrange includes in order.
- Add comment for completion timeout value.
- Remove blank lines.
- Indent the comments to code.
- Convert mutex_init() to devm_mutex_init().
- Remove 'IRQF_TRIGGER_FALLING' flag from devm_request_threaded_irq().
- Drop the duplicate message.
- Replace 'dev_info' with 'dev_dbg()'.
- Update 'dev_id' to 'pdata' in rfd77402_interrupt_handler().
- Drop 'interrupt mode' comment
- Use 'if(ret)' instead of 'if(ret < 0) for consistency.
- Use 'return i2c_smbus_write_byte_data()' in 'rfd77402_config_irq'.
