This patch renames this driver from tsl2x7x to tsl2772 since it is highly likely that additional devices will be added to this driver that do not match that wildcard. The tsl2772 driver name was selected since that is currently the device with the most features that are supported by this driver. This patch also adds Brian Masney's copyright to tsl2772.h for all of the work that has been done to move this driver out of staging. Signed-off-by:

The CALIBBIAS and INT_TIME masks in tsl2x7x_write_raw did not have any range checking in place so this patch adds the appropriate range checking. The defines TSL2X7X_ALS_GAIN_TRIM_{MIN,MAX} are also introduced by this patch. Signed-off-by: -

The thresh periods assumed an integration time of 3ms. This patch adds support for the correct integration time (2.72ms or 2.73ms). The code had the ALS filter values as going up to 15, however the values actually went up to 60 since the values scaled in increments of 5 once the persistence value went above 3. Signed-off-by:

Make the sysfs attributes in_proximity0_calibscale_available, and in_intensity0_{calibscale,integration_time}_available be created using info_mask_separate_available on the channel configuration. The driver assumed that the ALS increment was 2.72 ms, and the upper range was 696 ms. Some other supported devices use 2.73 ms - 699 ms. This patch adds support for the multiple ranges.

Adds the ability to run the Mag3110 in continuous mode to speed up the sampling rate. Depending on the sampling rate requested the device can be put in or out of continuous mode automatically. Shifting out of continuous mode requires a potential 1 / ODR wait which is also implemented. Modified the sleep method when data is not ready to allow for sampling > 50sps to work. Signed-off-by:

Prior to this loop, we check if fifo_count < bytes_per_datum and bail if so. This means that when we hit the loop, we know that fifo_count >= bytes_per_datum, so the check is unneeded and we can turn the loop into a do-while for a slight performance improvement. Signed-off-by:

The MMAL and V4L2 buffers had been disassociated, and linked on demand. Seeing as both are finite and low in number, and we now have the same number of each, link them for the duration. This removes the complexity of maintaining lists as the struct mmal_buffer context comes back from the VPU, so we can directly link back to the relevant V4L2 buffer. Signed-off-by:
-
Dave Stevenson authored
For historical reasons, the number of buffers passed to the VPU over MMAL did not match that passed from V4L2. That is a silly situation as the driver has to duplicate serialisation and other functions that have already been implemented in V4L2/videobuf2. As we had more V4L2 buffers than MMAL ones, the MMAL buffer headers were returned to the VPU immediately on being filled, which is now invalid. Match the number of buffers notified in queue_setup with that used in MMAL. Return buffers only when we get them from V4L2. Signed-off-by:

Dave Stevenson authored
There is no requirement to serialise bulk transfers as that is all done in VCHI, and if a second MMAL_MSG_TYPE_BUFFER_TO_HOST happened before the VCHI_CALLBACK_BULK_RECEIVED, then the service_callback thread is deadlocked. Remove the bulk_mutex so that multiple receives can be scheduled at a time. Signed-off-by:

Dave Stevenson authored
The struct mmal_msg_context was being allocated for every message being sent to the VPU, and freed when it came back. Whilst that is required behaviour for some messages (mainly the synchronous ones), it is wasteful for the video buffers that make up the majority of the traffic. Add to the buffer_init/cleanup hooks that it allocates/frees the msg_context required. v2: changes by anholt from the downstream tree: clean up indentation, pass an error value through, forward-declare the struct so we have less void * Signed-off-by: -

Interleaved RGB and single plane YUV formats can be delivered by the GPU without the secondary step of removing padding, as the bytesperline field can be set appropriately. Planar YUV needs the GPU to still remove padding, as there is no way to report that there is padding between the planes (ie on the height). The multi-planar formats are NOT applicable, as there is no easy way to make them contiguous in memory (ie one large allocation that gets broken up). The whole task is passed across to videobuf2 which has no notion of that requirement. v2: Changes by anholt from the downstream driver: Flag two more planar formats as needing padding removal, and remove broken userspace workaround.

We had the camera driver set up in a module_init function, but that meant that the camera driver would fail to load if it was initialized before VCHI. By attaching to this platform_device, it can get a defined load order. Signed-off-by:

Merge tag 'iio-for-4.18a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: 1st round of IIO new device support, features and cleanup for the 4.18 cycle A nice mix this time of excellent cleanups (many to send drivers speeding toward staging graduations) and new drivers / device support. A good part of this is Brian Masney's never ending task on the tsl2x7x driver. The end is in sight so hopefully we'll get that one out of staging very soon! New device support * AD5686 - Support AD5685R (was wrongly present as AD5685) - Support AD5672R, AD5676, AD5676, AD5684R and AD5686R 4 and 8 channel SPI DACs with various precisions. - Support AD5671R, AD5675R, AD5694, AD5694R, AD5695R, AD5696 and AD5696R I2C DACs with various percisions and numbers of channels. * Analog front end rescale driver - New driver. - Support current sensing usings a shunt resistor. - Support simple voltage dividers. - support simple current sense amplifiers. * TI dac5571 - New driver and device bindings supporting: dac5571, dac6571, dac7571, dac5574, dac6574, dac7574, dac5573, dac6573 and dac7573 * Meson-adc - Support for Meson AXG with DT bindings. * mpu6050 - Support the mpu9255 which only requires additional WHOAMI entry and compatible string. * st_lsm6dsx - Support for lsm330dlc combinded accelerometer and gyro sensors with DT bindings. * stm32_adc - Add support for STM32MP1 with bindings. Staging graduations * adis16201 after some excelent cleanup by Himanshu Jha. * adis16029 after some excelent cleanup by Shreeya Patel. New features: * ABI docs - Add core ABI docs for angle channels. * inv_mpu6050 - Provide support for the full range of interrupts the device supports. * st_accel - Add SMO8840 ACPI ID seen in the wild on some Lenovo machines. * stx104 - Provide a multiple gpio get function. Cleanups / Minor fixes * core - Use new nested structure support to improve kernel-doc. * ad2s1200 - Use be16_to_cpup instead of opencoding. * ad5686 - Indentation tidy up. - Switch to SPDX - Refactor to allow various numbers of channels. - Refactor to separate core and SPI specific support, prior to addition of i2c equivalent devices. * ad7606 - Use drvdata directly from device rather than boucing via the platform_device structure. * ad7746 - Replace opencoded byte swapped i2c calls with _swapped variants. - White space and line break readability improvements. - Reorder includes and variable declarations where appropriate. * ad7791 - Changes to the AD ADC library used by this driver took in the sampling frequency. This lead to be the wrong path being the one tied to the resulting attribute, so it didn't work, and a warning to be printed. * ad7780 - Remove apparent support for sampling frequency control on devices that don't support changing the sampling attributes. * ade7854 - Fix a read of the wrong number of bits. - Improve error handling on i2c read/write errors. - Rework i2c and spi code to reduce duplication. * adis16201 (staging) - Improve meaning inherent in some macro names by adding units etc where relevant. - Adjust comments to improve detail and drop the irrelevant. - Rename register address definitions definitions to add a _REG postfix, clearly separating them from field definitions. Reorganize the definitions to group register address and fields. - Use sign_extend32 rather than open coding. - Reverse Xmas tree ordering where appropriate and align function args. - Remove unused headers. - Use GENMASK where appropriate instead of open coding. * adis16209 (staging) - Indent field definitions to visually separate them from register address definitions. - Use reverse xmas tree ordering where appropriate. - Add some whitespace where it will help readability. - Drop some unused headers. - Use GENMASK where appropriate. * ad2s1200 - Drop unnecessary includes and reorder alphabetically. - Reverse xmas tree and blank line cleanups. * atlas-ph-sensor - Use msleep instead of usleep_range where the precise value doesn't matter and the delays are long. * bcm150 - Drop transaction splitting as core now handles it. * cros_ec - Move the shared header to the include/iio/common directory. This brings it inline with the other multiple type devices. - Use drvdata directly from device rather than boucing via the platform_device structure. * hid-sensors - Use drvdata directly from device rather than boucing via the platform_device structure. * inv_mpu6050 - Clear out a second function definition for the same function. - Don't flush fifo when the iio buffer is full but just drop excess data. - Tidy up set_power_itg and ensure it is used in the right places. - Use set_power_itg rather than opencoding it again in the i2c mux control. - Make sure error paths disable the power if undoing power on. - Used managed devm_ functions during probe. Delete remove function. - Refactor to pull raw data read out of read_raw function. - Simplify data reading error paths. - Only enable the i2c mux for chips with the i2c aux bus (not icm20608) - Fix a potential deadlock due to varying lock ordering. - Fix an issue where first sample from gyro after enabling is unstable by dropping the first sample. - Fix an issue where the user_ctrl register is incorrectly overwritten. - Tidy up some grammar and spelling minor issus. * mcp320x - Use vendor compatible strings. * mcp4018 - Switch to using i2c .probe_new. * mcp4351 - switch to using i2c .probe_new. * meson-adc - rework handing on common ADC platform data so it can be shared across multiple families of SoCs. * sca3000 - Fix an error handling path if the ring configure fails. * st_lsm6dsx - Fix a wrong fifo threshold mask (no actual effect) * stm32-dfsdm - Style fixes and cleanups. - Check filter ID is in range and check spi-max-frequency. * tsl2x7x (staging) - Drop some unnecessary function calls, unused variables and unnecessary local variables. - Fix wrong interrupt type. - Avoid unnecessary double clear of interrupt. - Simplify proximity calibration call which did various things unrelated to actually calibrating. - Separate control of the proximity and ALS interrupts. - Improve consistency of logging. - Separate ALS and proximity persistence settings as they have separate hardware controls. - Tidy up variable ordering. - Add Brian to copyright notice given consider work on this driver. - Take advantage of hardware support for I2C address auto increment. - Combine individuaal enable and period attributes for the two directions on the threshold events into a single value as the hardware doesn't separate them. - Move integration_time* attributes from light channel to intensity value as they effect the intensity readings directly and the light reading only indirectly. Hence this better reflects reality. Also move the calibscale_available. - Avoid returning an error in the IRQ handler. - Hard code the reg value in _clear_interrupts as it only takes one value in the code. Result is the function has little purpose so opencode the two remaining i2c_smbus_write_byte calls. - Drop some unnecessary checking of the chip status register. - Tidy up return path in _write_interrupt_config. - Tidy up the ID verification code. - Move the power and diode settings defines into the header as these are needed for platform data configuration. - Various renames and comment cleanups for consistency and clarity. - Use actual device defaults for default startup settings. - SPDX - Add some range sanity checking to sysfs attribute writes. - Don't provide event interfaces if the interrupt line isn't available. - Use IIO_CONST_ATTR macro for calibscale_available as it's a constant string. - Fix the integration time and lux equations. - Make device IDs explicit index values in the device_channel_config array.
