Starting with ACPI 6.2 bits 1 and 2 of the BGRT status field are no longer
reserved. These bits are now used to indicate if the image needs to be
rotated before being displayed.
The efifb code does not support rotating the image before copying it to
the screen.
This commit adds a check for these new bits and if they are set leaves the
fb contents as is instead of trying to use the un-rotated BGRT image.

When the driver is built-in for PCI, we reference the exit function
after discarding it:
`pvr2fb_pci_exit' referenced in section `.ref.data' of drivers/video/fbdev/pvr2fb.o: defined in discarded section `.exit.text' of drivers/video/fbdev/pvr2fb.o
Just remove the __exit annotation as the easiest workaround.
Also apply the same workaround for pvr2fb_dc_exit().

This is a really useful function, but it's buried in the
copy_ccw_from_iova() routine so that ccwchain_calc_length()
can just work with Format-1 CCWs while doing its counting.
But it means we're translating a full 2K of "CCWs" to Format-1,
when in reality there's probably far fewer in that space.
Let's factor it out, so maybe we can do something with it later.

It doesn't make much sense to "hide" the copy to the channel_program
struct inside a routine that calculates the length of the chain.
Let's move it to the calling routine, which will later copy from
channel_program to the memory it allocated itself.

Rather than allocating/freeing a piece of memory every time
we try to figure out how long a CCW chain is, let's use a piece
of memory allocated for each device.
The io_mutex added with commit 4f76617378ee9 ("vfio-ccw: protect
the I/O region") is held for the duration of the VFIO_CCW_EVENT_IO_REQ
event that accesses/uses this space, so there should be no race
concerns with another CPU attempting an (unexpected) SSCH for the
same device.

spmi_regulator_set_voltage_time_sel() calculates the amount of delay
needed as the result of setting a new voltage. Essentially this is the
absolute difference of the old and new voltages, divided by the slew rate.
The implementation of spmi_regulator_set_voltage_time_sel() is wrong.
It attempts to calculate the difference in voltages by using the
difference in selectors and multiplying by the voltage step between
selectors. This ignores the possibility that the old and new selectors
might be from different ranges, which have different step values. Also,
the difference between the selectors may encapsulate N ranges inbetween,
so a summation of each selector change from old to new would be needed.
Lets avoid all of that complexity, and just get the actual voltage
represented by both the old and new selector, and use those to directly
compute the voltage delta. This is more straight forward, and has the
side benifit of avoiding issues with regulator implementations that don't
have hardware register support to get the current configured range.

atmel_spi f0000000.spi: Using dma0chan2 (tx) and dma0chan3 (rx)

atmel_spi: probe of f0000000.spi failed with error -22
Commit 0a919ae49223 ("spi: Don't call spi_get_gpio_descs() before device name is set")
moved the calling of spi_get_gpio_descs() after ctrl->dev is set,
but didn't move the !ctrl->num_chipselect check. When there are
chip selects in the device tree, the spi-atmel driver lets the
SPI core discover them when registering the SPI master.
The ctrl->num_chipselect is thus expected to be set by
spi_get_gpio_descs().
Move the !ctlr->num_chipselect after spi_get_gpio_descs() as it was
before the aforementioned commit. While touching this block, get rid
of the explicit comparison with 0 and update the commenting style.

According to the DA9061 and DA9062 datasheets the LDO voltage selection
registers have a lower value of 0x02. This applies to voltage registers
VLDO1_A, VLDO2_A, VLDO3_A and VLDO4_A. This linear offset of 0x02 was
previously not observed by the driver, causing the LDO output voltage to
be systematically lower by two steps (= 0.1V).
This patch fixes the minimum linear selector offset by setting it to a
value of 2 and increases the n_voltages by the same amount allowing
voltages in the range 0x02 -> 0.9V to 0x38 -> 3.6V to be correctly
selected. Also fixes an incorrect calculaton for the n_voltages value in
the regulator LDO2.
These fixes effect all LDO regulators for DA9061 and DA9062.

If devm_gpiod_get_from_of_node() call returns ERR_PTR, it is assigned
into an array of GPIO descriptors and used later because such error is
not treated as critical thus it is not propagated back to the probe
function.
All code later expects that such GPIO descriptor is either a NULL or
proper value. This later might lead to dereference of ERR_PTR.
Only devices with S2MPS14 flavor are affected (other do not control
regulators with GPIOs).

The i3c bus spec defines a bus configuration where i2c devices don't
have a 50ns filter but support SCL running at SDR max rate (12.5MHz).
This patch introduces the limited bus mode so that users can use
a higher speed in presence of i2c devices index 1.

Currently the I3C framework limits SCL frequency to FM speed when
dealing with a mixed slow bus, even if all I2C devices are FM+ capable.
The core was also not accounting for I3C speed limitations when
operating in mixed slow mode and was erroneously using FM+ speed as the
max I2C speed when operating in mixed fast mode.

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.
Also, there is no need to store the individual debugfs file names,
especially as the whole directiry is deleted at once, so remove the
unneeded structure entirely.

The MPPE code uses the sync skcipher to invoke the ecb(arc4) skcipher,
of which only a single generic C code implementation exists. This means
that going through all the trouble of using scatterlists etc buys us
very little, and we're better off just invoking the arc4 library directly.
Note that the SHA1 shash used by this driver has several accelerated
implementations for various architectures, so retaining that part does
make sense.

Modify drivers to perform skcipher IV update using the crypto engine,
instead of performing the operation in SW.
Besides being more efficient, this also fixes IV update for CTR mode.
Output HW S/G table is appended with an entry pointing to the same
IV buffer used as input (which is now mapped BIDIRECTIONAL).
AS (Algorithm State) parameter of the OPERATION command is changed
from INIFINAL to INIT in descriptors used by ctr(aes), cbc(aes).
This is needed since in case FINAL bit is set, HW skips IV updating
in the Context Register for the last data block.

Currently, conversion of SW S/G table into HW S/G layout relies on
nents returned by sg_nents_for_len(sg, len).
However this leaves the possibility of HW S/G referencing more data
then needed: since buffer length in HW S/G entries is filled using
sg_dma_len(sg), the last entry in HW S/G table might have a length
that is bigger than needed for the crypto request.
This way of S/G table conversion is fine, unless after converting a table
more entries have to be appended to the HW S/G table.
In this case, crypto engine would access data from the S/G entry having
the incorrect length, instead of advancing in the S/G table.
This situation doesn't exist, but the upcoming implementation of
IV update for skcipher algorithms needs to add a S/G entry after
req->dst S/G (corresponding to output IV).
