Support for AMS AS73211 JENCOLOR(R) Digital XYZ Sensor. This driver has no built-in trigger. In order for making triggered measurements, an external (software) trigger driver like iio-trig-hrtimer or iio-trig-sysfs is required. The sensor supports single and continuous measurement modes. The latter is not used by design as this would require tight timing synchronization between hardware and driver without much benefit.

ADXRS290 is a high performance MEMS pitch and roll (dual-axis in-plane) angular rate sensor (gyroscope) designed for use in stabilization applications. It also features an internal temperature sensor and programmable high-pass and low-pass filters. Add support for ADXRS290 in direct-access mode for now.

Both irqnum and irqarray properties reflect the same thing: the number of bits and bytes for interrupts at this chipset. E. g.: irqnum = 8 x irqarray This can be seen by the way pending interrupts are handled: /* During probe time */ pmic->irqs = devm_kzalloc(dev, pmic->irqnum * sizeof(int), GFP_KERNEL); /* While handling IRQs */ for (i = 0; i < pmic->irqarray; i++) { pending = hi6421_spmi_pmic_read(pmic, (i + pmic->irq_addr)); pending &= 0xff; for_each_set_bit(offset, &pending, 8) generic_handle_irq(pmic->irqs[offset + i * 8]); } Going further, there are some logic at the driver which assumes that irqarray is 2: /* solve powerkey order */ if ((i == HISI_IRQ_KEY_NUM) && ((pending & HISI_IRQ_KEY_VALUE) == HISI_IRQ_KEY_VALUE)) { generic_handle_irq(pmic->irqs[HISI_IRQ_KEY_DOWN]); generic_handle_irq(pmic->irqs[HISI_IRQ_KEY_UP]); pending &= (~HISI_IRQ_KEY_VALUE); } As HISI_IRQ_KEY_DOWN and HISI_IRQ_KEY_UP are fixed values and don't depend on irqnum/irqarray. The IRQ addr and mask addr seem to be also fixed, based on some comments at the OF parsing code. So, get rid of them too, removing the of parsing function completely. Signed-off-by: -

Both the SPMI controller and the SPMI PMIC driver depends on the SPMI bus support. The dependency for the regulator is also wrong: it should depends on the SPMI version of the HiSilicon 6421, and not on the normal one. Signed-off-by:
