The change is mostly stylistic. The table should be indented with tabs instead of spaces. Signed-off-by:

The driver pretty much uses device managed functions. The only left-over is the iio_device_register() function, which also requires an action-or-reset hook to disable the regulator on the remove and error path. Signed-off-by:

Add support for the Atlas EZO O2 chemical sensor which required some refactoring of the driver and parsing of i2c transfer. Sensor data is converted by the scaling value from percent to IIO_CONCENTRATION. Signed-off-by:

The regulator driver needs it, as otherwise it will produce errors when creating vmlinux. Reported-by:

Currently the module can only be test built on ARM, although it seems to build fine on x86. Change this to allow for broader test coverage. Signed-off-by:

Add documentation for the properties needed by the HiSilicon 6421v600 driver, and by the SPMI controller used to access the chipset. Signed-off-by:

It is clear that this driver is for PMIC. So, get rid of it at the compatible. Signed-off-by:

Mauro Carvalho Chehab authored
Add the chipset name at the compatible string, as other HiSilicon chipsets with SPMI bus might require something different. Signed-off-by:

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:

Currently, an array is used to store both vsel and enable settings, mixing registers, masks and bit settings. Change it in order to have one separate property for each. This makes easier to understand the contents of the DT file, and to describe it at the Documentation/. Signed-off-by:

Without that, the regulator's core complains with: ldo17: ramp_delay not set For now, use the enable time, as we don't have any datasheets from this device. Signed-off-by: -

Using dev_dbg() is not too nice, as, instead of printing the name of the regulator, it prints "regulator.<number>", making harder to associate what is happening with each ldo line. So, add a debug-specific macro, which will print the rdev's name, just like the regulator core. Signed-off-by:

Instead of implementing a custom set of properties, set valid_modes_mask based on having or not a mask for enabling the eco_mode. This makes the code clearer, and remove some uneeded props from DT. Signed-off-by:

There are several fields on this struct that can be removed, as they already exists at struct regulator_desc. Remove them, cleaning up the code in the process. While here, rename it to hi6421v600_regulator_info, in order to better match the driver's name. Signed-off-by:

The driver was originally written for Kernel 4.9. It needs to be ported to upstream: - Got rid of timeval; - Removed a bogus dependency; - Did cleanups at the header file. Signed-off-by:

There are several OF properties that aren't used by Hikey 970, and some are not even used inside the driver. So, drop them, as as this makes easier to document what's actually used. If latter needed, those could be re-added later. Signed-off-by:
