This patch is removing the buffer allocation at each buffer enable. We just allocate enough memory in the main structure during probe to cover maximum size needed (that anyway is pretty small) [16bytes].

Martin Kepplinger authored
in_accel_x_scale, in_accel_y_scale and in_accel_z_scale are always the same. The scale is still defined to be in "info_mask_separate". Userspace (iio-sensor-proxy and others) is not used to that and only looks for "in_accel_scale" for the scaling factor to apply. Change IIO_CHAN_INFO_SCALE from being separate in all channel to be shared by type. This removes in_accel_x_scale, in_accel_y_scale and in_accel_z_scale and makes available in_accel_scale. This is an ABI change, but hopefully in the 'no one will notice' category. The cleanup in interface is worth the small risk that there is a custom script out there somewhere that this will break.

Use devm_add_action_or_reset to call tsl2772_chip_off when the device is removed. This also fixes the issue that the chip is turned off before the device is unregistered. Not marked for stable as fairly hard to hit the bug and this is in the middle of a set making other cleanups to the driver. Hence will probably need explicit backporting.

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

This patch is trying to cleanup for good the buffers operation functions. There is no need of using preenable, all can be done into postenable. Let's also use logical sequence of operations as already done in accel driver. Finally also rename the goto label using operation to perform and not where it fails. Not stable material as not fixing a 'bug' but rather bringing the driver in line with general 'patterns' to allow a subsystem wide cleanup.

Support for ad7616 running in software was added. In order to activate the software mode, HW_RNGSEL pins must be pulled low. Oversampling and input ranges are now configured in corresponding registers. Ad7616 has multiple scale options when it is configured in software mode. Also, in order to support multiple devices in software mode, the spi calculation of registers address must be generic. Because the length of address and bit which specifies the read/write operation is different for every device, calculation of address was made generic.

Because software mode and register access are only available in spi, they were moved in spi file and are accessbile via bops structure. The write_os/scale will be overwritten by sw_mode_config function. This patch was made in order to support devices in software mode without making the driver dependent to spi and increase the abstraction of the core.

Linus Walleij authored
The mounting matrix for sensors was introduced in commit dfc57732 ("iio:core: mounting matrix support") However the device tree bindings are very terse and since this is a widely applicable property, we need a proper binding for it that the other bindings can reference. This will also be useful for other operating systems and sensor engineering at large. I think all 3D sensors should support it, the current situation is probably that the mounting information is confined in magic userspace components rather than using the mounting matrix, which is not good for portability and reuse.

Embedded controller return minimum and maximum frequencies, unfortunately we have no way to know the step for all available frequencies. Even if not complete, we can return a list of known values using the standard read_avail callback (IIO_CHAN_INFO_SAMP_FREQ) to provide them to userland. Now cros_ec_* sensors provides frequencies values in sysfs like this: "0 min max". 0 is always true to disable the sensor. Default frequencies are provided for earlier protocol.
