Changes in v5: - Add precursor patch to reorder includes before functional changes. - Use devm_mutex_init() for proper lifetime management. - Address maintainer feedback on polling helper usage. - Remove dead code from interrupt_handler. - Add blank line in rfd77402_wait_for_irq. - Update measurement timeout comment. - Add helper function for result polling. - Fix comment format in rfd77402_init. - Remove 'data->irq_en = false', as it already initialized by kzalloc. - Improve documentation of private driver data. Signed-off-by: Shrikant Raskar --- Changelog: v3 to v4: - No code change. Link to v3: https://lore.kernel.org/all/20251221083902.134098-1-raskar.shree97@gmail.com/ v2 to v3: - 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'.
