commit 7abad1063deb0f77d275c61f58863ec319c58c5c upstream.
The different devices support by the adis16480 driver have slightly
different scales for the gyroscope and accelerometer channels.

commit 2ab5f39bc7825808e0fa1e7e5f0b23e174563467 upstream.
The DT-Property "atmel,adc-startup-time" is stored in an u8 for a microsecond
value. When trying to increase the value of STARTUP in Register AT91_ADC_MR
some higher values can't be reached.
Change the type in function parameter and private structure field from u8 to
u32.

commit adfa969850ae93beca57f7527f0e4dc10cbe1309 upstream.
The value sent on the SPI bus is shifted by an erroneous number of bits.
The shift value was already computed in the iio_chan_spec structure and
hence subtracting this argument to 16 yields an erroneous data position
in the SPI stream.

commit b136faff9bc2f4adea050ed2119c01199f9a86a5 upstream.
'channels' is allocated via kmemdup and it is never freed in the

commit c2a8b623a089d52c199e305e7905829907db8ec8 upstream.
We unfortunately can't use ~0UL for the scan mask to indicate that the
only valid scan mask is all channels selected. The IIO core needs the exact
mask to work correctly and not a super-set of it. So calculate the masked
based on the channels that are available for a particular device.

Previously, the two voltage channels had the same ID, which didn't cause

this is still violating the spec though, two indexed channels should never

commit 61bd55ce1667809f022be88da77db17add90ea4e upstream.
When creating the demux table we need to iterate over the selected scan mask for
the buffer to get the samples which should be copied to destination buffer.
Right now the code uses the mask which contains all active channels, which means
the demux table contains entries which causes it to copy all the samples from
source to destination buffer one by one without doing any demuxing.

commit 381676d5e86596b11e22a62f196e192df6091373 upstream.
The userspace interface for acceleration sensors is documented as using
m/s^2 units [Documentation/ABI/testing/sysfs-bus-iio]
The fullscale raw values for the BMA80 corresponds to -/+ 1, 1.5, 2, etc G
depending on the selected mode.
The scale table was converting to G rather than m/s^2.
Change the scaling table to match the documented interface.

for a related fix.

commit a2c12493ed7e63a18cef33a71686d12ffcd6600e upstream.
Currently in the inkern.c code for IIO framework, the function
of_iio_channel_get_by_name() will return a non-NULL pointer when
it cannot find a channel using of_iio_channel_get() and when it
tries to search for 'io-channel-ranges' property and fails. This
is incorrect behaviour as the function which calls this expects
a NULL pointer for failure. This patch rectifies the issue.

commit 2076a20fc1a06f7b0333c62a2bb4eeeac7ed1bcb upstream.
Ensure that querying the IIO buffer scan_mask returns a value of
0 or 1. Currently querying the scan mask has the value returned
by test_bit(), which returns either true or false. For some
architectures test_bit() may return -1 for true, which will appear
to return an error when returning from iio_scan_mask_query().
Additionally, it's important for the sysfs interface to consistently
return the same thing when querying the scan_mask.

commit bef44abccb2677e8d16e50b75316d4fd1061be81 upstream.
This effects the reported scale of the raw values, and thus userspace
applications that use this value.
One micro tesla equal 0.01 gauss. So I have fixed calculation formula And add RAW_TO_GAUSS macro.
ASA is in the range of 0 to 255. If multiply 0.003, calculation result(in_magn_[*]_scale) is
always 0. So multiply 3000 and return and IIO_VAL_INT_PLUS_MICRO.
As a result, read_raw call back function return accurate scale value.

commit 3425c0f7ac61f2fcfb7f2728e9b7ba7e27aec429 upstream.
A single channel in this driver was using the IIO_ST macro.
This does not provide a parameter for setting the endianness of
the channel. Thus this channel will have been reported as whatever
is the native endianness of the cpu rather than big endian. This
means it would be incorrect on little endian platforms.

Usually the active scan mask is freed in __iio_update_buffers() when the buffer
is disabled. But when the device is still sampling when it is removed we'll end
up disabling the buffers in iio_disable_all_buffers(). So we also need to free
the active scan mask here, otherwise it will be leaked.

We need to make sure that the IIO device is not freed while the character device
exists, otherwise the freeing of the IIO device might race against the file open
callback. Do this by setting the character device's parent to the IIO device,
this will cause the character device to grab a reference to the IIO device and
only release it once the character device itself has been removed.
Also move the registration of the character device before the registration of
the IIO device to avoid the (rather theoretical case) that the IIO device is
already freed again before we can add the character device and grab a reference
to the IIO device.
We also need to move the call to cdev_del() from iio_dev_release() to
iio_device_unregister() (where it should have been in the first place anyway) to
avoid a reference cycle. As iio_dev_release() is only called once all reference
are dropped, but the character device holds a reference to the IIO device.

Make sure that the IIO device is not freed while we still have file descriptors
for it.

Make sure to stop sampling when the device is removed, otherwise it will
continue to sample forever.
