2021-09-14iio: adc: rzg2l_adc: Fix -EBUSY timeout error returnColin Ian King
Currently when a timeout occurs in rzg2l_adc_hw_init the error -EBUSY is assigned to ret but the error code is used as the function is hard-coded to return 0. The variable ret is 0 before entering the while-loop hence the fix is just to return ret at the end of the function to return the success 0 or -EBUSY return code.

The bindings file for this driver is defining the property as 'reg' but the driver was reading it with the 'num' name. The bindings actually had the 'num' property when added in commit ea52c21268e6 ("dt-bindings: iio: dac: Add docs for AD5770R DAC") and then changed it to 'reg' in commit 2cf3818f18b2 ("dt-bindings: iio: dac: AD5570R fix bindings errors"). However, both these commits landed in v5.7 so the assumption is that either 'num' is not being used or if it is, the validations were not done. Anyways, if someone comes back yelling about this, we might just support both of the properties in the future. Not ideal, but that's life...

However, the reference to that object is kept on both the st_sensor_data struct and the IIO object parent (indio_dev->dev.parent). This change only adds a bit consistency and uses the reference stored on indio_dev->dev.parent, to enforce the assumption that all ST sensors' devm_ calls are bound to the same reference as the one store on st_sensor_data.

2021-09-14iio: st_sensors: disable regulators after device unregistrationAlexandru Ardelean
Up until commit ea7e586bdd331 ("iio: st_sensors: move regulator retrieveal to core") only the ST pressure driver seems to have had any regulator disable. After that commit, the regulator handling was moved into the common st_sensors logic. In all instances of this regulator handling, the regulators were disabled before unregistering the IIO device. This can cause issues where the device would be powered down and still be available to userspace, allowing it to send invalid/garbage data. This change moves the st_sensors_power_disable() after the common probe functions. These common probe functions also handle unregistering the IIO device.

This driver supports devices with 14-bit and 16-bit sample sizes. This implies different SPI transfer lengths which are not always handled properly by some SPI controllers. To work around this limitation, define a big endian buffer used to split the buffer into two 8-bit messages in the event that the controller doesn't support 14-bit or 16-bit transfers. A separate buffer is introduced here to avoid performing operations on types of different endianness. Since all transfers use the same bits_per_word value, move that logic to the probe function, and let transfers default to the value defined in the struct spi_device.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull IIO and staging driver updates from Greg KH: "Here is the big set of staging and IIO driver updates for 5.15-rc1. Also included in here are the counter driver subsystem updates as the IIO drivers needed them. Lots of churn in some staging drivers, we dropped the "old" rtl8188eu driver and replaced it with a newer version of the driver that had been maintained out-of-tree by Larry with the end goal of actually being able to get this driver out of staging eventually. Despite that driver being "newer" the line count of this pull request is going up. Some drivers moved out of staging as well, which is always nice to see, that is why there are additions to the mfc and misc driver subsystems. All of these were acked by the various subsystem maintainers involved. But by far, as normal, it's coding style cleanups all over the drivers/staging/ tree in here. Full details of these changes are in the shortlog. All of these have been in linux-next for a while with no reported problems" [ Note: the r8188eu merge clashed with commit 89939e890605 ("staging: rtlwifi: use siocdevprivate") from the networking tree. When resolving the issue, I noted that the whole r8188eu rtw_android code is dead since commit ae7471cae00a ("staging: r8188eu: remove rtw_ioctl function"). End result: the merge resolution was to throw all of that away, rather than do the mindless fixup to code that isn't actually reachable - Linus ] * tag 'staging-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (551 commits) staging: vt6655: Remove filenames in files staging: r8188eu: add extra TODO entries staging: vt6656: Remove filenames in files staging: wlan-ng: fix invalid assignment warning staging: r8188eu: rename fields of struct rtl_ps staging: r8188eu: remove ODM_DynamicPrimaryCCA_DupRTS() staging: r8188eu: rename fields of struct dyn_primary_cca staging: r8188eu: rename struct field Wifi_Error_Status staging: r8188eu: Provide a TODO file for this driver staging: r8188eu: remove unneeded variable staging: r8188eu: remove unneeded conversions to bool staging: r8188eu: remove {read,write}_macreg staging: r8188eu: core: remove condition with no effect staging: r8188eu: remove ethernet.h header file staging: r8188eu: remove ip.h header file staging: r8188eu: remove if_ether.h header file staging: r8188eu: make rtw_deinit_intf_priv return void staging: r8188eu: use is_multicast_ether_addr in os_dep/recv_linux.c staging: r8188eu: use is_multicast_ether_addr in hal/rtl8188eu_xmit.c staging: r8188eu: use is_multicast_ether_addr in core/rtw_xmit.c ...

2021-08-15iio: ltc2983: fix device probeNuno Sá
There is no reason to assume that the IRQ rising edge (indicating that the device start up phase is done) will happen after we request the IRQ. If the device is already up by the time we request it, the call to 'wait_for_completion_timeout()' will timeout and we will fail the device probe even though there's nothing wrong. Fix it by just polling the status register until we get the indication that the device is up and running. As a side effect of this fix, requesting the IRQ is also moved to after the setup function.

2021-08-08iio: accel: bmc150: Add support for BMC156Stephan Gerhold
BMC156 is another accelerometer that works just fine with the bmc150-accel driver. It's very similar to BMC150 (also a accelerometer + magnetometer combo) but with only one accelerometer interrupt pin. It would make sense if only INT1 was exposed but someone at Bosch decided to only have an INT2 pin. Try to deal with this by making use of the INT2 support introduced in the previous commit and force using INT2 for BMC156. To detect that we need to bring up a simplified version of the previous type IDs. Note that unlike the type IDs removed in commit c06a6aba6835 ("iio: accel: bmc150: Drop misleading/duplicate chip identifiers") here I only add one for the special case of BMC156. Everything else still happens by reading the CHIP_ID register since the chip type information often is not accurate in ACPI tables.
