The RTL8822BE, an 802.11ac wireless network card, is now appearing in new computers. Its driver is being placed in staging to reduce the time that users of this new card will have access to in-kernel drivers. This commit enables building of the new driver. For this version, all routines are built into a single module r8822be. When this driver is moved to the wireless tree, halmac, phydm, and rtl8822be will become new modules. Signed-off-by:

Its driver is being placed in staging to reduce the time that users of this new card will have access to in-kernel drivers. New Realtek wireless devices have a new method for PHY control and dynamic management. The RTL8822BE is the first of these devices, thus there is additional code required. In the final version, this code will be a separate module; however, it is combined with the r8822be driver to minimize the interference with the drivers in the wireless tree. Signed-off-by:

The RTL8822BE, an 802.11ac wireless network card, is now appearing in new computers. Its driver is being placed in staging to reduce the time that users of this new card will have access to in-kernel drivers. New Realtek devices implement a common sub-driver to control the MAC layer. The RTL8822BE is the first of these devices, thus its introduction involves some extra code. In the wireless tree, this will be a separate module; however, it is compiled into the 8822be driver here.

Its driver is being placed in staging to reduce the time that users of this new card will have access to in-kernel drivers. This commit copies the code that currently constitutes the rtlwifi and rtl_pci mini drivers. This material is copied into staging to prevent any undo interaction between the existing drivers and this new one. The only changes in this code are the removal of all export statements, and the fixing of some checkpatch messages. The latter will be backported into the wireless tree. Signed-off-by:

We want to concatonate join string one, a '/' character, string two and then a NUL terminator. The destination buffer holds ori_gf->gf_pathlen characters. The strlen() function returns the number of characters not counting the NUL terminator. So we should be adding two extra spaces, one for the foward slash and one for the NUL. Signed-off-by:

Merge tag 'iio-for-4.14b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of IIO new device support, features and cleanup for the 4.14 cycle. New device support: * ak8974 - support the AMI306. * st_magnetometer - add support for the LIS2MDL with bindings. * rockchip-saradc - add binding for rv1108 SoC (no driver change). * srf08 - add srf02 (i2c only) and srf10 support. * stm32-timer - support for the STM32H7 to existing driver. Features: * tools - move over to the tools buildsystem rather than hand rolling. - add an install section to the build. * ak8974 - use serial number to add device randomness. - add AMI306 calibration data output. * ccs811 - triggered buffer support. * srf08 - add a device tree table as the old style i2c probing is going away, - add triggered buffer support * st32-adc - add optional st,min-sample-time-nsecs binding to allow control of sampling against analog circuitry. * stm32-timer - add output compare triggers. * ti-ads1015 - add threshold event support. * ti-ads7950 - Allow use on ACPI platforms including providing a default reference voltage as there is no way to obtain this on ACPI currently. Cleanup and fixes: * ad7606 - fix an error return code in probe. * ads1015 - fix incorrect data rate setting update when capture in progress, - fix wrong scale information for the ADS1115, - make conversions work when CONFIG_PM is not set, - make sure we don't get a stale result after a runtime resume by ensuring we wait long enough, - avoid returning a false error form the buffer setup callbacks, - add enough wait time to get the correct conversion, - remove an unnecessary config register update, - add a helper to set conversion mode reducing repeated boilerplate, - use devm_iio_triggered_buffer_setup to simplify error and remove paths, - use iio_device_claim_direct_mode instead of opencoding the same. * ak8974 - mark the INT_CLEAR register as precious to prevent debugfs access. * apds9300 - constify the i2c_device_id. * at91-sama5 adc - add missing Kconfig dependency. * bma180 accel - constify the i2c_device_id. * rockchip_saradc - explicitly request exclusive reset control as part of the reset rework on going throughout the kernel. * st_accel - fix drdy configuration for a load of accelerometers that only have the int1 line. Fix is unimportant as presumably no deviec tree actually used the non existent hardware line. * st_pressure - fix drdy configuration for LPS22HB and LPS25H by dropping int2 support as they don't have this. Fix is unimportant as presumably no device tree actually used the non existent hardware line. * stm32-dac - explicitly request exclusive reset control (part of reset being reworked). * tsl2583 - constify the i2c_device_id. * xadc - coding style fixes.

Commit a53e35db ("reset: Ensure drivers are explicit when requesting reset lines") started to transition the reset control request API calls to explicitly state whether the driver needs exclusive or shared reset control behavior. Convert all drivers requesting exclusive resets to the explicit API call so the temporary transition helpers can be removed. No functional changes.

The ADS1015 device provides programmable comparator that can issue an interrupt on the ALERT pin. This change adds the iio threshold event support for that feature. The ADS1015 device only have a single config register which contains an input multiplexer selection, comparator settings, and etc. So only a single event channel can be enabled at a time. Also enabling both buffer and event are prohibited for simplicity. Cc: Daniel Baluta <daniel.baluta@gmail.com> Cc: Jonathan Cameron <jic23@kernel.org> Signed-off-by:

While the iio buffer for the ti-ads1015 driver is enabled, reading the raw ADC channel data is restricted. We usually use the iio_device_claim_direct_mode()/iio_device_release_direct_mode() pair for that. This change consequently reverses the locking order for the driver's private lock and indio_dev->mlock which acquired by iio_device_claim_direct_mode() internally. But it's safe because there is no other dependency between these locks. Cc: Daniel Baluta <daniel.baluta@gmail.com> Cc: Jonathan Cameron <jic23@kernel.org> Signed-off-by:

Use devm_iio_triggered_buffer_setup to simplify the error path in the probe() and remove() function. This changes the remove order, but the end result of remove function actually does the reverse of probe.

The ti-ads1015 driver has eight iio voltage channels and each iio channel can hold own scale information. The ADS1015 device only have a single config register which contains an input multiplexer selection, PGA and data rate settings. So the driver should load the correct settings when the input multiplexer selection is changed. However, regardless of which channlel is currently selected, changing any iio channel's scale information immediately overwrites the current PGA setting in the config register. It is harmless because the correct PGA settings are reloaded just before getting adc result anyway. But it is unnecessary register update and should be removed.

This driver assumes that the device is operating in the continuous conversion mode which performs the conversion continuously. So this driver inserts a wait time before reading the conversion register if the configuration is changed from a previous request. Currently, the wait time is only the period required for a single conversion that is calculated as the reciprocal of the sampling frequency. However we also need to wait for the the previous conversion to complete. Otherwise we probably get the conversion result for the previous configuration when the sampling frequency is lower.

pm_runtime_get_sync() and pm_runtime_put_autosuspend() return 0 on success, 1 if the device's runtime PM status was already requested status or error code on failure. So a positive return value doesn't indicate an error condition. However, any non-zero return values from buffer preenable and postdisable callbacks are recognized as an error and this driver reuses the return value from pm_runtime_get_sync() and pm_runtime_put_autosuspend() in these callbacks. This change fixes the false error detections. Cc: Daniel Baluta <daniel.baluta@gmail.com> Signed-off-by:

This driver assumes that the device is operating in the continuous conversion mode which performs the conversion continuously. So this driver doesn't insert a wait time before reading the conversion register if the configuration is not changed from a previous request. This assumption is broken if the device is runtime suspended and entered a power-down state. The forthcoming request causes reading a stale result from the conversion register as the device is runtime resumed just before. Fix it by adding a flag to detect that condition and insert a necessary wait time. Cc: Daniel Baluta <daniel.baluta@gmail.com> Signed-off-by:

The ADS1015 device have two operating modes, continuous conversion mode and single-shot mode. This driver assumes that the continuous conversion mode is selected by runtime resume callback when the ADC result is requested. If CONFIG_PM is disabled, the device is always in the default single-shot mode and no one begins a single conversion. So the conversion register doesn't contain valid ADC result. Fix it by changing the continuous mode in probe function. Cc: Daniel Baluta <daniel.baluta@gmail.com> Signed-off-by:

The ti-ads1015 driver supports ADS1015 and ADS1115 devices. The same scale information is used for both devices in this driver, however they have actually different values and the ADS1115's one is not correct. These devices have the same full-scale input voltage range for each PGA selection. So instead of adding another hardcoded scale information, compute a correct scale on demand from each device's resolution. Cc: Daniel Baluta <daniel.baluta@gmail.com> Signed-off-by:

So the driver should load the correct settings when the input multiplexer selection is changed. However, regardless of which channlel is currently selected, changing any iio channel's sampling frequency information immediately overwrites the current data rate setting in the config register. It breaks the current data rate setting if the different channel's sampling frequency information is changed because the data rate setting is not reloaded when the input multiplexer is switched. This removes the unexpected config register update and correctly load the data rate setting before getting adc result. Cc: Daniel Baluta <daniel.baluta@gmail.com> Signed-off-by:

The config_log_add() function first calls config_log_put() with the variable 'cld' and then jumps to label 'out_cld', which will call the same function with the same 'cld' variable. However, at this point, 'cld' might have been already freed by the first invocation of config_log_put(). Even if we remove the invocation at that point, we will still get into trouble. This is because, in the error path, just below the label 'out_cld', we try to put 'params_cls' and 'sptlrpc_cld', which might also have been freed by config_log_put(). The point is that, config_llog_data::cld_sptlrpc and config_llog_data::cld_params members are assigned at the beginning of this function. To avoid this, do not call config_log_put() inside the else block, immediately jump to 'out_cld' instead. Moreover, remove assignments to config_llog_data::cld_sptlrpc and config_llog_data::cld_params at the beginning, since we already assign them below in the function with 'cld_lock' held. As an additional benefit, code size gets smaller. before: text data bss dec hex filename 26188 2256 4208 32652 7f8c drivers/staging/lustre/lustre/mgc/mgc_request.o after: text data bss dec hex filename 26092 2256 4208 32556 7f2c drivers/staging/lustre/lustre/mgc/mgc_request.o Signed-off-by:
