2021-06-14staging: rtl8188eu: convert DBG_88E calls in core/rtw_sta_mgt.cPhillip Potter1-2/+5
Convert both calls to the DBG_88E macro in core/rtw_sta_mgt.c into netdev_dbg calls. The DBG_88E macro is unnecessary, as visibility of debug messages can be controlled more precisely by just using debugfs. It is important to keep these messages still, as they are displayable via a kernel module parameter when using DBG_88E.

Remove HW_DEF_ODM_DBG_FLAG definition from the hal_def_variable enum in include/hal_intf.h, and remove its usage from the switch statement in rtw_hal_get_def_var inside hal/usb_halinit.c - this is dead code and no longer used, now that ODM_RT_TRACE and include/odm_debug.h have been removed.

There needs to be a check to verify that we don't read beyond the end of "buf". This function is called from do_rx(). The "buf" is the USB transfer_buffer and "len" is "urb->actual_length".

2021-06-12staging: drop kpc2000 driverGreg Kroah-Hartman20-3714/+0
It seems that the old developer is no longer with the company producing this device, and the company has no plans on getting this out of the staging directory at all, so let's drop the driver for now as it's pretty much abandonded. If someone want to support this and get it out of staging, we can easily revert this change and bring it back.

Jonathan writes: 1st set of new IIO/counter device support, features and cleanup for 5.14 There are a couple of large cleanup sets in here alongside a number of new drivers. Note an immutable branch merged to add a stub for i2c_verify_client() as needed to avoid a build issue in the fxls8962af driver as a result of a workaround for a device errata that only applies when i2c interface is used. Counters ======== New device support * intel,quadrature encoder peripheral found on Elkhart Lake platforms. - New driver. IIO === New device support * amstaos,tsl2591 ambient light sensor. - New driver + bindings - Follow up fix to ensure some local variables are suitable for error handling. * fsl,fxls8962af + fsl,fxls8964af accelerometers - New driver + bindings - Includes an errata work around that cause a build bot failure fixed by adding a stub to i2c. * kionix,kxcjk-1013 - Add support for KX023-1025 device. Mostly a different register map that needed to be supported. * murata,sca3300 accelerometer - New driver + bindings * st,lsm9ds0 IMU - Rework of st,sensors driver to cleanly support this new glue driver that enables the two parts of the LSM9DS0. * ti,tsc2046 touchscreen controller ADC. - New driver. Intent here is to use this with existing IIO consumer drivers such as resistive-adc-touch. - Follow up fix to avoid an issue with unsigned subtraction in error check. * ti,tmp117 digital temperature sensor - New driver + bindings Features * adi,ad5755 - Add missing dt-binding doc * adi,ad7298 - Add ACPI ID used on Intel Galileo Gen 1 boards. - Add missing dt-binding doc * adi,ad7476 - Add missing dt-binding doc * adi,ad7746 - Add missing dt-binding doc for this driver that will hopefully move out of staging shortly. Update staging driver to use the binding instead of platform data. * adi,adis16201 + adis16209 - Add missing dt-binding doc * adi,adis16480 - Support burst mode for adis16495 and adis16497 parts. * bosch,bma220 - Add missing dt-binding doc * fsl,mma7455 - Add missing dt-binding doc * iio-rescale - Support handling of processed channels from provider. Some ADCs require (typically non linear) calibration functions to be applied, and so provide only IIO_CHAN_INFO_PROCESSED read back. They can be used as providers to the iio-rescale driver which needs to handle them somewhat differently from IIO_CHAN_INFO_RAW * sensiron,sps30 - Support the serial interface. Note this required significant refactoring of existing driver. * st,st-sensors - Add mount matrix support for normal dt-binding whilst continuing to support the odd ACPI approach for accelerometers. * ti,dac082s085 + similar - Add missing dt-binding doc * trivial-devices - add entries for - memsic,mx4005, memsic,mx6255 and memsic,mxc6655 - sensortek,stk8312 and sensortek,stk8ba50 Cleanup / minor fixes * core - Use devm_add_action_or_reset() to replace boilerplate in several driver and core IIO devm_* functions. - Fix an error path issue introduced by above, that could return an error pointer rather than the expected null from dev_iio_device_alloc() - Move more IIO internals related fields from struct iio_dev to struct iio_dev_opaque. - Drop unused final update of in_loc in demux setup. * Docs - Move some docs from driver specific to core dos to avoid replication of names which the documentation builder does not allow. Note this means adding a few device specific notes to the general docs to cover the more unusual uses of the ABI. - ABI: Move old buffer/* and scan_elements/* docs to obsolete as now we have the bufferX/* variant. Not we are not getting rid of these interfaces, just encouraging new code to use the new interface. * IIO wide: - Tidy up new cases of dev.parent etc being set in drivers as the core now does it. - Fix more cases of possible miss-aligned buffers when passed to iio_push_to_buffers_with_timestamp(). Note we only have one known instance of anyone seeing this bug actually happening, so this has been a low priority cleanup effort for several cycles. - sysfs_emit() used in more drivers. - Runtime pm tidy up and use of pm_runtime_resume_and_get() - Buffer alignment fixes as iio_push_to_buffers_with_timestamp requires that the timestamp when inserted by naturally aligned + consumers can assume that all fields are naturally aligned. Part of a long running effort, with at least 2 more series to come tackling additional variants. - Stop specifying "mount-matrix" property name in every lookup of the mount matrix from firmware by hard coding it in the core. * adi,ad7476 - Handle the variety of different regulators used by the parts supported by this driver (came up in dt-binding review) * adi,ad7746 - Trivial drop of if (ret) return ret; return 0; pattern - Tidy up comments - Pull capdac setup out to own function. * adi,ad7766 - Trivial drop of if (ret) return ret; return 0; pattern * adi,adis - Avoid returning error codes in interrupt handlers. - Handle a failure in spi_write in the trigger handler. - Rework to add updating of device page after changing it. - Don't push data to IIO buffers when read failed. - Add configuration of burst max speed to core avoid handling this in each driver. - Use the adis_dev_lock() helper in adis16260 and adis16136 drivers. - Excessive includes cleanup via include-what-you-use static checker after zero day highlighted that these needed updating. * afe - Amend binding to add #io-channel-cells, thus allowing this IIO consumer to also be an IIO provider. * aosong,am2315 - Drop ACPI id. Unlikely this one is in the wild and it isn't valid ACPI naming. * bosch,bma180 - Adding missing bandwidth settings (500, 1000 Hz) * bosch,bme680 - Drop ACPI id. Unlikely this one is in the wild and it isn't valid ACPI naming. * ep93xx_adc, - Drop a redundant error print. * maxim,max118 - Convert remainder of probe() to devm_ managed functions. - Avoid some repeated jumping back and forth between iio_dev and spi structures. * maxim,max11100 - Use get_unaligned_be16() instead of open coding. - Convert remainder of probe() to devm_ managed functions. * samsung,exynos_adc - Unused error value dropped. * sensiron,sgp30 - Drop use of %hx in favor of %x and letting the normal type conversion work. * sensortek,stk8312 - Add lowercase device id and note uppercase version deprecated. - Drop ACPI id. Unlikely this one is in the wild and it isn't valid ACPI naming. * sprx,sc72xx_adc - add MODULE_DEVICE_TABLE * st,lsm6dsx - Fix docs of valid ODRs * st,sensors - dt-binding rework. Two efforts on this crossed in a previous cycle so this update cherry picks the best of the two yaml conversions. - Don't copy the channel spec array as now ext_info is no longer modified. * st,stm32-adc - tidy up some docs that were marked as kernel-doc but aren't. * ti,adc081c, ti,adc0832, ti,adc108s102 and ti,adc161s626 - Convert remainder of probe() functions to devm_ managed functions to simplify error handing and remove paths. * tag 'iio-for-5.14a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (171 commits) i2c: core: Add stub for i2c_verify_client() if !CONFIG_I2C iio: adis: Cleanout unused headers iio: accel: bma180: Add missing 500 Hz / 1000 Hz bandwidth counter: Add support for Intel Quadrature Encoder Peripheral staging: iio: cdc: ad7746: extract capac setup to own function staging: iio: cdc: ad7746: clean up probe return staging: iio: cdc: ad7746: remove ordinary comments iio: adc: ti-adc161s626: Use devm managed functions for all of probe. iio: adc: ti-adc108s102: Use devm managed functions for all of probe() iio: adc: ti-adc0832: Use devm managed functions for all of probe() iio: adc: ti-adc081c: Use devm managed functions for all of probe() iio: adc: max1118: Avoid jumping back and forth between spi and iio structures iio: adc: max1118: Use devm_ managed functions for all of probe iio: adc: max11100: Use devm_ functions for rest of probe() iio: adc: max11100: Use get_unaligned_be16() rather than opencoding. iio: chemical: sgp30: Drop use of %hx in format string. iio: gyro: st_gyro: Support mount matrix iio: magnetometer: st_magn: Support mount matrix iio: accel: st_sensors: Stop copying channels iio: accel: st_sensors: Support generic mounting matrix ...

2021-06-08media: hantro: Introduce G2/HEVC decoderBenjamin Gaignard7-0/+1208
Implement all the logic to get G2 hardware decoding HEVC frames. It supports up level 5.1 HEVC stream. It doesn't support yet 10 bits formats or the scaling feature. Add HANTRO HEVC dedicated control to skip some bits at the beginning of the slice header. That is very specific to this hardware so can't go into uapi structures. Computing the needed value is complex and requires information from the stream that only the userland knows so let it provide the correct value to the driver.
