commit f7a28df7db84eb3410e9eca37832efa5aed93338 upstream.
If we have an unexpected number of channels then return -EINVAL instead

commit 4170d3dd1467e9d78cb9af374b19357dc324b328 upstream.
The ssp_print_mcu_debug() function should return negative error codes on
error. Returning "length" is meaningless. This change does not affect
runtime because the callers only care about zero/non-zero.

Update the error handling path accordingly.

[ Upstream commit 97683c851f9cdbd3ea55697cbe2dcb6af4287bbd ]
The naming of the regulator is problematic. VCC is usually a supply
voltage whereas these devices have a separate VREF pin.
Secondly, the regulator core might have provided a stub regulator if
a real regulator wasn't provided. That would in turn have failed to
provide a voltage when queried. So reality was that there was no way
to use the internal reference.
In order to avoid breaking any dts out in the wild, make sure to fallback
to the original vcc naming if vref is not available.

commit 5afc1540f13804a31bb704b763308e17688369c5 upstream.
Currently the for-loop that scans for the optimial adc_period iterates
through all the possible adc_period levels because the exit logic in
the loop is inverted. I believe the comparison should be swapped and
the continue replaced with a break to exit the loop at the correct
point.

commit 84edec86f449adea9ee0b4912a79ab8d9d65abb7 upstream.
The datasheets have the following note for the conversion time
specification: "This parameter is specified by design and/or
characterization and it is not tested in production."
Parts have been seen that require more time to do 14-bit conversions for
the relative humidity channel. The result is ENXIO due to the address
phase of a transfer not getting an ACK.
Delay an additional 1 ms per conversion to allow for additional margin.

commit 8090d67421ddab0ae932abab5a60200598bf0bbb upstream
According to the BMA253 datasheet [1] and BMA250 datasheet [2] the
bandwidth value for BMA25x should be set as 01xxx:
"Settings 00xxx result in a bandwidth of 7.81 Hz; [...]
It is recommended [...] to use the range from ´01000b´ to ´01111b´
only in order to be compatible with future products."
However, at the moment the drivers sets bandwidth values from 0 to 6,
which is not recommended and always results into 7.81 Hz bandwidth
according to the datasheet.
Fix this by introducing a bw_offset = 8 = 01000b for BMA25x,
so the additional bit is always set for BMA25x.

commit 421a26f3d7a7c3ca43f3a9dc0f3cb0f562d5bd95 upstream.
The ltr559 chip uses only the lowest bit of the ALS_CONTR register to
configure between active and stand-by mode. In the original driver
BIT(1) is used, which does a software reset instead.
This patch fixes the problem by using BIT(0) as als_mode_active for
the ltr559 chip.

commit 2ac0b029a04b673ce83b5089368f467c5dca720c upstream.
The regmap is configured for 8 bit registers, uses a RB-Tree cache and
marks several registers as volatile (i.e. do not cache).
The ALS and PS data registers in the chip are 16 bit wide and spans
two regmap registers. In the current driver only the base register is
marked as volatile, resulting in the upper register only read once.
Further the data sheet notes:
| When the I2C read operation starts, all four ALS data registers are
| locked until the I2C read operation of register 0x8B is completed.
Which results in the registers never update after the 2nd read.
This patch fixes the problem by marking the upper 8 bits of the ALS
and PS registers as volatile, too.

commit 7cd04c863f9e1655d607705455e7714f24451984 upstream.
Allocating an IRQ is conditional to the IRQ existence, but freeing it
was not. If no IRQ was allocate, the driver would still try to free
IRQ 0. Add the missing checks.
This fixes the following trace when the driver is removed:

Whilst running some basic tests as part of writing up the dt-bindings for
this driver (to follow), it became clear it doesn't actually load
currently.

adis16201: probe of spi0.0 failed with error -16
Looks like a cut and paste / update bug. Fixes tag obviously not accurate
but we don't want to bother carry thing back to before the driver moved
out of staging.

Seems that there are config combinations in which this driver gets enabled
and hence selects the MFD, but with out HAS_IOMEM getting pulled in
via some other route. MFD is entirely contained in an
if HAS_IOMEM block, leading to the build issue in this bugzilla.
