The rtl8723bs is found on quite a few systems used by Linux users, such as on Atom systems (Intel Computestick and various other Atom based devices) and on many (budget) ARM boards such as the CHIP. The plan moving forward with this is for the new clean, written from scratch, rtl8xxxu driver to eventually gain support for sdio devices. But there is no clear timeline for that, so lets add this driver included in staging for now.

Despite the user payload may not be bigger than (2**16 - 1) bytes, the final packet size may be bigger because of the gap space needed for the controller. This patch removes the temporary variables of the type u16 that are used to hold the offsets that may be bigger than 2**16 bytes. Signed-off-by:

The final size of the buffer used for the streaming transfer consists of the size for the user payload (buffer_size) and the size for the gaps needed by the controller (extra_len). The current implementation of the hdm_configure_channel() corrects the buffer size down to the next appropriate for the hardware value, that is the whole number of frames, but uses the old unaligned value to calculate the extra_len. Current patch fixes the described problem. Signed-off-by:

When a channel is being removed while an application holds the corresponding character device, this device is going to be destroyed only after the application closes the file descriptor and releases character device. In case the channel appears again before the application closes the file descriptor it holds, the channel cannot be linked. This patch changes the described behavior and destroys the character device at the time the channel get disconnected from the AIM. Signed-off-by:

Currently an AIM has the following properties available to manage links: - write-only "remove_link" used to remove a link from a list - read/write "add_link" used to add a link to a list and display them This patch transfers the read functionality of "add_link" to the new read-only property "links" to build consistent set of properties to control the list of links.

Technically, calling dma_buf_map_attachment should return a buffer properly dma_mapped. Add calls to dma_map_sg to begin_cpu_access to ensure this happens. As a side effect, this lets Ion buffers take advantage of the dma_buf sync ioctls. Signed-off-by:

Merge tag 'iio-for-4.12c' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Third set of new device support, cleanups and features for IIO in the 4.12 cycle Somewhat dominated in patch numbers of last of the outreachy application window related patches (they are still coming, despite window being closed which is good to see!) Good set of new drivers as well. New device support * ASPEED ADC - new driver * cpcap PMIC ADC - new driver * hid-humidity - driver for HID compatible humidity sensors. * ltc2497 ADC - new driver * mpu6050 - bring bindings up to date and add trivial support for 9250 * rockchip-saradc - update bindings to cover rk3328 * vl6180 light, proximity and time of flight sensor. - new driver Features * meson-saradc - add calibration Cleanup and minor fixes * ad5504 - constify attribute_group structure - drop casting of void * * ad7150 - replace some shifts of 1 by BIT macro usage * ad7152 - blank lines between function definitions * ad7280a - octal permissions. * ad7606 - replace use of core mlock mutex with a local lock * ad7746 - replace some shifts of 1 by BIT macro usage - function parameter alignment - drop some excessive brackets (introduced in last pull request) * ad7753 - white space cleanup * ad7754 - includes in alphabetical order and groupped appropriately. - change from missuse of internal mlock mutex to using the buffer lock to also protect values during frequency update. * ad779x - constify attribute_group structures * ad9832 - octal permissions * adis16060 - remove use of core mlock mutex in favour of adding a local _spi_write_then_read which can use the local buffer protection lock. - fix naming of above function. * adis16203 - remove locking during reads of calibbias that doesn't protect anything not protected elsewhere. * adis16209 - remove unnecessary braces in single statement if * adis16240 - remove unnecessary braces in single statement if * adt7136 - drop excess blank lines and put some in between functions. * ams-iaq - replace comma with semi colon. Not actual bug, just unusual syntax. * apds9960 - constify attribute group structure * as3935 - constify attribute group structure * bm1750 - constify attribute group structure * cros_ec - devm version of triggered buffer setup to simplify code. * exynos - drop casting of void * * hdc100x - constify attribute_group structure * hid-accel - fix wrong scale for newly introduced gravity sensor. * hts221 - drop casting of void * * hx711 - constify attribute_group structure * imx7d_adc - drop casting of void * * lm35333 - constify attribute_group structure * lsm6dsx - drop casting of void * - hold ODR configuration until enabling to avoid a race condition. * max1027 - drop casting of void * * max11100 - fix a comma where semicolon was intended (no actual bug, just odd) * max1363 - constify attribute_group structure * ms sensors - drop casting of void * * rockchip_saradc - drop casting of void * * sun4i-gpadc - fix missing dependency on THERMAL or presence of stubs (issue only introduced in pervious set) - drop casting of void * * tsl2x7x - fix wrong standard deviation calc. Note these aren't actually used for anything at the moment so bug didn't really matter. - constify attribute group structure. * vf610adc - drop casting of void * * vz89x - replace comma with semicolon. Not actual bug, just odd syntax. * zpa2326 - drop casting of void *

This patch allows to avoid a transitory that occurs when a given sensor has been already enabled (e.g. gyroscope) and the user is configuring the sample frequency of the other one (e.g. accelerometer). The transitory lasts until the accelerometer is enabled. During that time slice the gyroscope ODR is incorrectly modified as well. At the end of the transitory both sensors work at the right frequency. Fix it introducing st_lsm6dsx_check_odr() routine to check ODR consistency in write_raw handler in order to apply frequency configuration just in st_lsm6dsx_set_odr() Fixes: 290a6ce1 (iio: imu: add support to lsm6dsx driver) Signed-off-by:

With CONFIG_THERMAL=m and CONFIG_SUN4I_GPADC=y, we get a link error from calling devm_thermal_zone_of_sensor_register: drivers/iio/built-in.o: In function `sun4i_gpadc_probe': :(.text+0x1c284): undefined reference to `devm_thermal_zone_of_sensor_register' This adds a Kconfig dependency to ensure we can only have the ADC driver as built-in when this function is also built-in, or when we see the empty stub implementation. When the thermal code is a module, we can still build the adc driver as a module, too. Signed-off-by:

The mpu9250 is a SIP containing an mpu6500 and an ak8975. If this was all there was too it there would be no need for explicit handling in the driver. Arguably the bindings would also only reflect the presence of an mpu6500 with the ak8975 hanging off it, as the kernel doesn't care that they are in one package. However, the WHOAMI value changes as well so best to add explicit support. Signed-off-by: -

These bindings are somewhat lagging the state of the driver. The i2c-gate bindings are documented elsewhere, but it seems sensible to at least have an example and cross reference in here. SPI bindings will need to be the subject of a future patch. Signed-off-by:
