We used to do this before 3453d5708b33, but this was changed to better
handle the NFS4ERR_SEQ_MISORDERED error code. This commit fixed the slot
re-use case when the server doesn't receive the interrupted operation,
but if the server does receive the operation then it could still end up
replying to the client with mis-matched operations from the reply cache.
We can fix this by sending a SEQUENCE to the server while recovering from
a SEQ_MISORDERED error when we detect that we are in an interrupted slot
situation.

[ Upstream commit ed7815db70d17b1741883f2da8e1d80bc2efe517 ]
A SPI transfer defines the _maximum_ speed of the SPI transfer. However the
driver doesn't take into account that the clock divider is always rounded down
(due to integer arithmetics). This results in a too high clock rate for the SPI
transfer.
E.g.: with a mclk_rate of 24 MHz and a SPI transfer speed of 10 MHz, the
original code calculates a reg of "0", which results in a effective divider of
"2" and a 12 MHz clock for the SPI transfer.
This patch fixes the issue by using DIV_ROUND_UP() instead of a plain
integer division.
While there simplify the divider calculation for the CDR1 case, use
order_base_2() instead of two ilog2() calculations.

A client driver (renesas_usbhs) assumed that
dmaengine_tx_status() could return the residue even if
the transfer was completed. However, this was not correct
usage [1] and this caused to break getting the residue after
the commit 24461d9792c2 ("dmaengine: virt-dma: Fix access after

wrong received size if the usb controller gets a short packet.
For example, g_zero driver causes "bad OUT byte" errors.
To use the tx_result from the renesas_usbhs driver when
the transfer is completed, set the tx_result parameters.
Notes that the renesas_usbhs driver needs to update for it.

One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses a 40 byte array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data with alignment
explicitly requested. This data is allocated with kzalloc so no
data can leak appart from previous readings.

with the optional clocks enabled.
This is based on what we're already doing for legacy platform data booting

The Acer TravelMate 5735Z shipped with Windows 7 and as such does not
trigger our "win8 ready" heuristic for preferring the native backlight
interface.
Still ACPI backlight control doesn't work on this model, where as the
native (intel_video) backlight interface does work by adding
`acpi_backlight=native` or `acpi_backlight=none` to Linux’ command line.
So, add a quirk to force using native backlight control on this model.

Apparently MMS345L does not have the MMS152_COMPAT_GROUP register

TSP FW Rev: bootloader 0x6 / core 0x26 / config 0x26, Compat group: \x06
On earlier kernel versions the compat group was actually printed as

But we probably shouldn't print something from a random register.
Add a separate "melfas,mms345l" compatible that avoids reading
from the MMS152_COMPAT_GROUP register. This might also help in case
there is some other device-specific quirk in the future.

MicroBook IIc operates in UAC2 mode by default. This patch addresses
several issues with it:
- MicroBook II and IIc shares the same USB ID. We can distinguish them
by interface class.
- MaxPacketsOnly attribute is erroneously set in endpoint descriptors.
As a result this card produces noise with all sample rates other than
96 KHz. This also causes issues like IOMMU page faults and other
problems with host controller.
- Sample rate changes takes more than 2 seconds for this device. Clock
validity request returns false during that period, so the clock validity
quirk is required.

We are currently setting -1 for non-existing sysconfig related registers
for quirks, but setting -ENODEV elsewhere. And for matching the quirks,
we're now just ignoring the non-existing registers. This will cause issues
with misdetecting DSS registers as the hardware revision numbers can have
duplicates.
To avoid this, let's standardize on using -ENODEV also for the quirks
instead of -1. That way we can always just test for a match without adding
any more complicated logic.

This kernel configuration is basically enabling/disabling sr driver quirks
detection. While these quirks are for fairly rare devices (very old CD
burners, and a glucometer), the additional detection of these models is a
very minimal amount of code.
The logic behind the quirks is always built into the sr driver.
This also removes the config from all the defconfig files that are enabling
this already.

For the ux500v2 variant of the PL18x block, any block sizes
are supported. This is necessary to support some SDIO
transfers. This also affects the QCOM MMCI variant and the
ST micro variant.
For Ux500 an additional quirk only allowing DMA on blocks
that are a power of two is needed. This might be a bug in
the DMA engine (DMA40) or the MMCI or in the interconnect,
but the most likely is the MMCI, as transfers of these
sizes work fine for other devices using the same DMA
engine. DMA works fine also with SDIO as long as the
blocksize is a power of 2.
This patch has proven necessary for enabling SDIO for WLAN on
PostmarketOS-based Ux500 platforms.
What we managed to test in practice is Broadcom WiFi over
SDIO on the Ux500 based Samsung GT-I8190 and GT-S7710.
This WiFi chip, BCM4334 works fine after the patch.
Before this patch:
brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac4334-sdio

mmci-pl18x 80118000.sdi1_per2: unsupported block size (60 bytes)

brcmfmac: brcmf_sdio_download_firmware: dongle image file download

After this patch:
brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4334/3 wl0:
Nov 21 2012 00:21:28 version 6.10.58.813 (B2) FWID 01-0
Bringing up networks, discovering networks with "iw dev wlan0 scan"
and connecting works fine from this point.
This patch is inspired by Ulf Hansson's patch
http://www.spinics.net/lists/linux-mmc/msg12160.html
As the DMA engines on these platforms may now get block sizes
they were not used to before, make sure to also respect if
the DMA engine says "no" to a transfer.
Make a drive-by fix for datactrl_blocksz, misspelled.

[ Upstream commit 4601832f40501efc3c2fd264a5a69bd1ac17d520 ]
The IPU1 MMU has been using common IOMMU pdata quirks defined and
used by all IPU IOMMU devices on OMAP4 and beyond. Separate out the
pdata for IPU1 MMU with the additional .set_pwrdm_constraint ops
plugged in, so that the IPU1 power domain can be restricted to ON
state during the boot and active period of the IPU1 remote processor.
This eliminates the pre-conditions for the IPU1 boot issue as
described in commit afe518400bdb ("iommu/omap: fix boot issue on
remoteprocs with AMMU/Unicache").
NOTE:
1. RET is not a valid target power domain state on DRA7 platforms,
and IPU power domain is normally programmed for OFF. The IPU1
still fails to boot though, and an unclearable l3_noc error is
thrown currently on 4.14 kernel without this fix. This behavior
is slightly different from previous 4.9 LTS kernel.
2. The fix is currently applied only to IPU1 on DRA7xx SoC, as the
other affected processors on OMAP4/OMAP5/DRA7 are in domains
that are not entering RET. IPU2 on DRA7 is in CORE power domain
which is only programmed for ON power state. The fix can be easily
scaled if these domains do hit RET in the future.
3. The issue was not seen on current DRA7 platforms if any of the
DSP remote processors were booted and using one of the GPTimers
5, 6, 7 or 8 on previous 4.9 LTS kernel. This was due to the
errata fix for i874 implemented in commit 1cbabcb9807e ("ARM:
DRA7: clockdomain: Implement timer workaround for errata i874")
which keeps the IPU1 power domain from entering RET when the
timers are active. But the timer workaround did not make any
difference on 4.14 kernel, and an l3_noc error was seen still
without this fix.
