Add i2c_device_id table for the vcnl4035 driver, enabling device instantiation using i2c_new_client_device() or from userspace in cases where device-tree based description is not possible now, like device(s) on a gbphy i2c adapter created by greybus. Signed-off-by:

The only usage of mma8452_event_attribute_group is to assign its address to the event_attrs field in the iio_info struct, which is a const pointer. Make it const to allow the compiler to put it in read-only memory. This was the only non-const static struct in drivers/iio. Signed-off-by:

This change removes the old platform data for ad7298. It is only used to provide whether to use an external regulator as a reference. So, the logic is inverted a bit. The driver now tries to obtain a regulator. If one is provided, then the external ref is used. The rest of the logic should work as before. Signed-off-by:

Fixes IIO_VAL_FRACTIONAL for case when the result is negative and exponent is 0. example: if the result is -0.75, tmp0 will be 0 and tmp1 = 75 This causes the output to lose sign because of %d in snprintf which works for tmp0 <= -1.

The order in which 'users' counter is decremented vs calling drivers' close() method is implementation specific, and we should not rely on it. Let's introduce driver private flag and use it to signal ISR to exit when device is being closed. This has a side-effect of fixing issue of accessing inut->users outside of input->mutex protection.

Add support for setting the hysteresis as a shifted value of a channel's proximity threshold. Each channel can have a different threshold, but the hysteresis applies to all channels as a right shift factor. Therefore, duplicate the hysteresis value across all channels and make it depend on the channel's proximity threshold. This is sort of odd but seems to work in practice as most of the time only one channel is used. Signed-off-by:

This change inverts/reworks the logic to use an external reference via a provided regulator. Now the driver tries to obtain a regulator. If one is found, then it is used. The rest of the driver logic already checks if there is a non-NULL reference to a regulator, so it should be fine. Signed-off-by:

The AT91 ADC driver no longer uses the 'at91_add_device_adc' platform data type. This is no longer used (at least in mainline boards). This change removes the platform-data initialization from the driver, since it is mostly dead code now. Some definitions [from the platform data at91_adc.h include] have been moved in the driver, since they are needed in the driver. Signed-off-by:

This tries to solve a warning reported by the lkp bot: >> drivers/iio/adc/at91_adc.c:1439:34: warning: unused variable >> 'at91_adc_dt_ids' [-Wunused-const-variable] static const struct of_device_id at91_adc_dt_ids[] = { ^ 1 warning generated. This warning has appeared after the AT91_ADC driver compilation has been enabled via the COMPILE_TEST symbol dependency. The warning is caused by the 'of_match_ptr()' helper which returns NULL if OF is undefined. This driver should build only for device-tree context, so a dependency on the OF Kconfig symbol has been added. Also, the usage of of_match_ptr() helper has been removed since it shouldn't ever return NULL (because the driver should not be built for the non-OF context).

The main intent is to get rid of the cast for the void-pointer returned by of_device_get_match_data(). This requires const-ifying the 'caps' and 'registers' references on the at91_adc_state struct. The caps can be obtained also from the old platform_data (in the at91_adc_probe_pdata() function), but that cast is not touched in this patch, since the old platform_data should be removed/cleaned-away. Also, that cast deals with converting a kernel_ulong_t type to a pointer. So, updating that cast doesn't yield any benefit. Signed-off-by:

The device can be connected on SPI or on SDIO. The original file described the two options separately. So, most of the file had to be rewritten in order to match with the Yaml requirements. Some device requirements are still written in the comments since they cannot been expressed with the current scheme (e.g. reg must be set to 1 with SDIO, interrupt is mandatory with SPI, reset-gpio in SPI is replaced by mmc-pwrseq in SDIO, etc...). The examples provided have also been reworked in order to make dt_binding_check happy. Finally, also fix typo in the name of the file (siliabs instead of silabs) Signed-off-by:

The device is in charge of respecting the QoS constraints. The driver have to ensure that all the queues contain data and the device choose the right queue to send. The things starts to be more difficult when the bandwidth of the bus is lower than the bandwidth of the WiFi. The device quickly sends the frames of the highest priority queue. Then, it starts to send frames from a lower priority queue. Though, there are still some high priority frames waiting in the driver. To work around this problem, this patch add some priorities to each queue. The weigh of the queue was (roughly) calculated experimentally by checking the speed ratio of each queue when the bus does not limit the traffic: - Be/Bk -> 20Mbps/10Mbps - Vi/Be -> 36Mbps/180Kbps - Vo/Be -> 35Mbps/600Kbps - Vi/Vo -> 24Mbps/12Mbps So, if we fix the weigh of the Background to 1, the weight of Best Effort should be 2. The weight of Video should be 116. However, since there is only 32 queues, it make no sense to use a value greater than 64[1]. And finally, the weight of the Voice is set to 128. [1] Because of this approximation, with very slow bus, we can still observe frame starvation when we measure the speed ratio of Vi/Be. It is around 35Mbps/1Mbps (instead of 36Mbps/180Kbps). However, it is still in accepted error range. Signed-off-by: -

Firmwares with API < 3.6 do not forward DELBA requests. Thus, when a Block Ack session is restarted, the reordering buffer is not flushed and the received sequence number is not contiguous. Therefore, mac80211 starts to wait some missing frames that it will never receive. This patch disables the reordering buffer for old firmware. It is harmless when the network is unencrypted. When the network is encrypted, the non-contiguous frames will be thrown away by the TKIP/CCMP replay protection. So, the user will observe some packet loss with UDP and performance drop with TCP.

As expected, when the device detect a MMIC error, it returns a specific status. However, it also strip IV from the frame (don't ask me why). So, with the current code, mac80211 detects a corrupted frame and it drops it before it handle the MMIC error. The expected behavior would be to detect MMIC error then to renegotiate the EAP session. So, this patch correctly informs mac80211 that IV is not available. So, mac80211 correctly takes into account the MMIC error. Signed-off-by:
