Before activating a buffer make sure that at least one channel is enabled. Activating a buffer with 0 channels enabled doesn't make too much sense and disallowing this case makes sure that individual driver don't have to add special case code to handle it. Currently, without this patch enabling a buffer is possible and no error is produced. With this patch -EINVAL is returned. An example of execution with this patch and some instrumented print-code: root@analog:~# cd /sys/bus/iio/devices/iio\:device3/buffer root@analog:/sys/bus/iio/devices/iio:device3/buffer# echo 1 > enable 0: iio_verify_update 748 indio_dev->masklength 2 *insert_buffer->scan_mask 00000000 1: iio_verify_update 753 2:__iio_update_buffers 1115 ret -22 3: iio_buffer_store_enable 1241 ret -22 -bash: echo: write error: Invalid argument 1, 2 & 3 are exit-error paths. 0 the first print in iio_verify_update() rergardless of error path. Without this patch (and same instrumented print-code): root@analog:~# cd /sys/bus/iio/devices/iio\:device3/buffer root@analog:/sys/bus/iio/devices/iio:device3/buffer# echo 1 > enable 0: iio_verify_update 748 indio_dev->masklength 2 *insert_buffer->scan_mask 00000000 root@analog:/sys/bus/iio/devices/iio:device3/buffer# Buffer is enabled with no error. Note from Jonathan: Probably not suitable for automatic application to stable. This has been there from the very start. It tidies up an odd corner case but won't effect any 'real' users.

snprintf() is a hard-to-use function, it's especially difficult to use it for concatenating substrings in a buffer with a limited size. Since snprintf() returns the would-be-output size, not the actual size, the subsequent use of snprintf() may go beyond the given limit easily. Although the current code doesn't actually overflow the buffer, it's an incorrect usage. This patch replaces such snprintf() calls with a safer version, scnprintf(). Also this fixes the incorrect argument of the buffer limit size passed to snprintf(), too. The size has to be decremented for the remaining length. Signed-off-by:

The BMI088 is pin-compatible with the BMI055, and provides both gyro and accel functions. The gyro part is similar to the BMI055 and this adds the chip to the list of supported devices for the gyro part. The accel part of the chip is not compatible with anything existing already. Signed-off-by:

Commit 3862828a ("iio: buffer: Switch to bitmap_zalloc()") introduced bitmap_alloc(), but commit 20ea39ef ("iio: Fix scan mask selection") reverted it. This change adds it back. The only difference is that it's adding bitmap_zalloc(). There might be some changes later that would require initializing it to zero. In any case, now it's already zero-ing the trialmask. Appears to have been the result of merge conflict resolution rather than an intentional revert. Reviewed-by:

This driver seems to use most of the AD_SD_*_CHANNEL. This change will move them in the driver. The intent is that if a new part comes along which would require tweaks per IIO channel, these should be doable in the driver. Signed-off-by:

Alexandru Ardelean authored
This change gets rid of the AD_SD_*_CHANNEL macros in favor of defining it's own. The ad7780 is quite simpler than it's other Sigma-Delta brothers. It turned out that centralizing the AD_SD_*_CHANNEL macros doesn't scale too well, especially with some more complicated drivers. Some of the variations in the more complicated drivers require new macros, and that way things can become harder to maintain. Signed-off-by:

AD7091R is already supported by this driver. While AD7091R allows the choice of an internal or an external voltage reference, for AD7091 the reference is only provided by VDD. Since this information is anyway obtained through the "vcc" regulator, no other driver changes are required for adding AD7091 support as well. Signed-off-by:

Dragos Bogdan authored
Compared to the other supported parts, AD7091R are dependent of a CONVST signal that initiates the conversion. At this moment, only sampling in buffered mode is supported for AD7091R and the only option until now was to generate this signal externally using an IIO trigger. This patch adds the option of generating it internally, more compatible triggers being available in this case. Also, it is an intermediate step of adding support more devices. Signed-off-by:

There is no need to call unaligned helpers on stack placed variables because compiler will align them correctly, accordingly to architectural ABI. Moreover, using bitwise type makes it explicit to see what we are reading in bulk transfer. On top of that, use sizeof() instead of magic value. Signed-off-by:

Function 'devm_gpiod_get_index_optional' returns NULL if the descriptor is invalid and the error associated for the error pointer is ENOENT. Sometimes if the pin is just assigned the error associated for the pointer might not be ENOENT but other. In order to avoid weirds behaviours if this happen set descriptor to NULL in the driver port structure. Signed-off-by:

This soc has two phy's for the pcie one of them using just a different register for settig it up but sharing all the rest of the config. Until now we was presenting this schema as three different phy's in the device tree using the 'phy-cells' node property to discriminate an index and setting up a complete phy for the dual port index. This sometimes worked properly but reconfiguring the same registers twice presents sometimes some unstable pcie links and the ports was not properly being detected. The problems only appears on hard resets and soft resets was properly working. Instead of having this schema just set two phy's in the device ree and use the 'phy-cells' property to say if the port has or not a dual port. Doing this configuration and set up becomes easier, LOC is decreased and the behaviour also gets deterministic with properly and stable pcie links in both hard and soft resets. Signed-off-by:
