Device specific platform support has been haphazard for Ion. There have been several independent attempts and there are still objections to what bindings exist right now. Just remove everything for a fresh start. Signed-off-by:

ION_IOC_MAP is the same as ION_IOC_SHARE. We really don't need two identical interfaces. Remove it. Signed-off-by:

With the expansion of dma-buf and the move for Ion to be come just an allocator, the import mechanism is mostly useless. There isn't a kernel component to Ion anymore and handles are private to Ion. Remove this interface. Signed-off-by:

Ion is now moving towards a unified interfact. This makes the custom ioctl interface unneeded. Remove it. Signed-off-by:

Now that we call dma_map in the dma_buf API callbacks there is no need to use the existing cache APIs. Remove the sync ioctl and the existing bad dma_sync calls. Explicit caching can be handled with the dma_buf sync API. Signed-off-by:

The new method of syncing with dma_map means that the page faulting sync implementation is no longer applicable. Remove it. Signed-off-by:

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:

Ion currently returns a single sg_table on each dma_map call. This is incorrect for later usage. Signed-off-by:

The align field was supposed to be used to specify the alignment of the allocation. Nobody actually does anything with it except to check if the alignment specified is out of bounds. Since this has no effect on the actual allocation, just remove it. Signed-off-by:

The reference counting of dma_map calls was removed. Remove the associated counter field as well. 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.

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:

On Motorola phones like droid 4 there is a custom CPCAP PMIC. This PMIC has ADCs that are used for battery charging and USB PHY VBUS and ID pin detection. Unfortunately the only documentation for this ADC seems to be the Motorola mapphone Linux kernel tree. I have tested that reading raw and scaled values works, but I have not used the timed sampling that the ADC seems to support. Let's add a minimal support for it so we can eventually provide IIO channels for the related battery charging and USB PHY drivers.
