2021-03-25Input: move to use request_irq by IRQF_NO_AUTOEN flagBarry Song11-28/+18
disable_irq() after request_irq() still has a time gap in which interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable because of requesting. On the other hand, request_irq() after setting IRQ_NOAUTOEN as below irq_set_status_flags(irq, IRQ_NOAUTOEN); request_irq(dev, irq...); can also be replaced by request_irq() with IRQF_NO_AUTOEN flag.

Setup TC before the i40e_setup_pf_switch() call. Memory must be initialized for all the queues before using its resources. Previously it could be possible that a call: xdp_rxq_info_reg(&rx_ring->xdp_rxq, rx_ring->netdev, rx_ring->queue_index, rx_ring->q_vector->napi.napi_id); was made with q_vector being null.

Fix the reason of kernel oops when i40e driver removed VFs. Added new __I40E_VFS_RELEASING state to signalize releasing process by PF, that it makes possible to exit of reset VF procedure. Without this patch, it is possible to suspend the VFs reset by releasing VFs resources procedure. Retrying the reset after the timeout works on the freed VF memory causing a kernel oops.

2021-03-25iio: cros: unify hw fifo attributes without API changesGwendal Grignou6-25/+13
Commit 2e2366c2d141 ("iio: cros_ec: unify hw fifo attributes into the core file") should be reverted as it set buffer extended attributes at the wrong place. However, to revert it will requires to revert more commits: commit 165aea80e2e2 ("iio: cros_ec: use devm_iio_triggered_buffer_setup_ext()") commit 21232b4456ba ("iio: buffer: remove iio_buffer_set_attrs() helper")). and we would still have conflict with more recent development. commit ee708e6baacd ("iio: buffer: introduce support for attaching more IIO buffers") Instead, this commit reverts the first 2 commits without re-adding iio_buffer_set_attrs() and set the buffer extended attributes at the right place: 1. Instead of adding has_fw_fifo, deduct it from the configuration: - EC must support FIFO (EC_FEATURE_MOTION_SENSE_FIFO) set. - sensors send data a regular interval (accelerometer, gyro, magnetomer, barometer, light sensor). - "Legacy accelerometer" is only present on EC without FIFO, so we don't need to set buffer attributes. 2. devm_iio_triggered_buffer_setup_ext() does not need to be called when EC does not support FIFO, as there is no FIFO to manage. 3. Use devm_iio_triggered_buffer_setup_ext() when EC has a FIFO to specify the buffer extended attributes.

2021-03-25iio: kfifo: add devm_iio_triggered_buffer_setup_ext variantAlexandru Ardelean1-6/+10
This is similar to the {devm_}iio_triggered_buffer_setup_ext variants added via commit 5164c7889857 ("iio: triggered-buffer: add {devm_}iio_triggered_buffer_setup_ext variants"). These can be used to pass extra buffer attributes to the buffer object. This is a bit of temporary mechanism (hopefully) so that drivers that want to allocate a kfifo buffer with extra buffer attributes, don't need to include 'buffer_impl.h' directly. This can also become an API function (in it's own right, unfortunately), but it may be a little less bad vs drivers having to include 'buffer_impl.h'. So, far the drivers that want to pass buffer attributes, all have to do with some HW FIFO attributes, so there may be a chance of unifying them into IIO core somehow (as some standard API). But, until that happens, we just need to let them register their HW FIFO attributes directly (without having to let them include 'buffer_impl.h' directly).

2021-03-25iio: buffer: fix use-after-free for attached_buffers arrayAlexandru Ardelean3-7/+8
Thanks to Lars for finding this. The free of the 'attached_buffers' array should be done as late as possible. This change moves it to iio_buffers_put(), which looks like the best place for it, since it takes place right before the IIO device data is free'd. The free of this array will be handled by calling iio_device_free(). The iio_buffers_put() function is renamed to iio_device_detach_buffers() since the role of this function changes a bit. It looks like this issue was ocurring on the error path of iio_buffers_alloc_sysfs_and_mask() and in iio_buffers_free_sysfs_and_mask() Added a comment in the doc-header of iio_device_attach_buffer() to mention how this will be free'd in case anyone is reading the code and becoming confused about it.

2021-03-25hwmon: (ntc_thermistor): try reading processedLinus Walleij1-9/+18
Before trying the custom method of reading the sensor as raw and then converting, we want to use iio_read_channel_processed_scale() which first tries to see if the ADC can provide a processed value directly, else reads raw and applies scaling inside of IIO using the scale attributes of the ADC. We need to multiply the scaled value with 1000 to get to microvolts from millivolts which is what processed IIO channels returns. Keep the code that assumes 12bit ADC around as a fallback. This gives correct readings on the AB8500 thermistor inputs used in the Ux500 HREFP520 platform for reading battery and board temperature.

2021-03-25iio: chemical: atlas: Remove code to set trigger parentGwendal Grignou1-1/+0
iio_trigger_set_drvdata() sets the trigger device parent to first argument of viio_trigger_alloc(), no need to do it again in the driver code. Given we call devm_iio_trigger_alloc() and devm_iio_device_alloc() with &client->dev as parent, we do not have to set data->trig->dev.parent to indio_dev->dev.parent anymore.

2021-03-25iio: set default trig->dev.parentGwendal Grignou11-29/+37
When allocated with [devm_]iio_trigger_alloc(), set trig device parent to the device the trigger is allocated for by default. It can always be reassigned in the probe routine. Change iio_trigger_alloc() API to add the device pointer to be coherent with devm_iio_trigger_alloc, using similar interface to iio_device_alloc().

2021-03-25iio: adc: ad7124: allow more than 8 channelsAlexandru Tachici1-158/+301
Currently AD7124-8 driver cannot use more than 8 IIO channels because it was assigning the channel configurations bijectively to channels specified in the device-tree. This is not possible to do when using more than 8 channels as AD7124-8 has only 8 configuration registers. To allow the user to use all channels at once the driver will keep in memory configurations for all channels but will program only 8 of them at a time on the device. If multiple channels have the same configuration, only one configuration register will be used. If there are more configurations than available registers only the last 8 used configurations will be allowed to exist on the device in a LRU fashion.

2021-03-25iio: proximity: Add a ChromeOS EC MKBP proximity driverStephen Boyd3-0/+283
Add support for a ChromeOS EC proximity driver that exposes a "front" proximity sensor via the IIO subsystem. The EC decides when front proximity is near and sets an MKBP switch 'EC_MKBP_FRONT_PROXIMITY' to notify the kernel of proximity. Similarly, when proximity detects something far away it sets the switch bit to 0. For now this driver exposes a single sensor, but it could be expanded in the future via more MKBP bits if desired.
