2022-06-19iio: adc: rzg2l_adc: add missing fwnode_handle_put() in ↵Jialin Zhang1-2/+6
rzg2l_adc_parse_properties() fwnode_handle_put() should be used when terminating device_for_each_child_node() iteration with break or return to prevent stale device node references from being left behind.

2022-06-19iio: adc: stm32-adc: Use generic_handle_domain_irq()Sebastian Andrzej Siewior1-1/+1
The call chain generic_handle_irq(irq_find_mapping(domain, x)); could be replaced with generic_handle_domain_irq(domain, x); which looks up the struct irq_desc for the interrupt and handles it with handle_irq_desc(). This is a slight optimisation given that the driver invokes only one function and the struct irq_desc is used directly instead being looked up via irq_to_desc(). Use generic_handle_domain_irq().

2022-06-18iio: adc: qcom-spmi-rradc: introduce round robin adcCaleb Connolly3-0/+1035
The Round Robin ADC is responsible for reading data about the rate of charge from the USB or DC input ports, it can also read the battery ID (resistence), skin temperature and the die temperature of the pmic. It is found on the PMI8998 and PM660 Qualcomm PMICs.
