SJA1105, being AVB/TSN switches, provide hardware assist for the
Credit-Based Shaper as described in the IEEE 8021Q-2018 document.
First generation has 10 shapers, freely assignable to any of the 4
external ports and 8 traffic classes, and second generation has 16
shapers.
The Credit-Based Shaper tables are accessed through the dynamic
reconfiguration interface, so we have to restore them manually after a
switch reset. The tables are backed up by the static config only on
P/Q/R/S, and we don't want to add custom code only for that family,
since the procedure that is in place now works for both.
Tested with the following commands:
data_rate_kbps=67000
port_transmit_rate_kbps=1000000
idleslope=$data_rate_kbps
sendslope=$(($idleslope - $port_transmit_rate_kbps))
locredit=$((-0x80000000))

mt76 core uses ffs() to find the next free bit. This works well for 32 bit
architectures where BITS_PER_LONG is 32. ffs only checks 32 bit values, so
allocation fails on 64 bit architectures.
Additionally, the wcid mask array was too small in cases where the array
was not a multiple of BITS_PER_LONG.
Fix this by making the wcid mask array u32 instead and use DIV_ROUND_UP
for the size, just in case we ever bump it to a value that's not a multiple
of 32.

Baikal-T1 SoC provides an embedded process, voltage and temperature
sensor to monitor an internal SoC environment (chip temperature, supply
voltage and process monitor) and on time detect critical situations,
which may cause the system instability and even damages. The IP-block
is based on the Analog Bits PVT sensor, but is equipped with a
dedicated control wrapper, which provides a MMIO registers-based access
to the sensor core functionality (APB3-bus based) and exposes an
additional functions like thresholds/data ready interrupts, its status
and masks, measurements timeout. All of these is used to create a hwmon
driver being added to the kernel by this commit.
The driver implements support for the hardware monitoring capabilities
of Baikal-T1 process, voltage and temperature sensors. PVT IP-core
consists of one temperature and four voltage sensors, each of which is
implemented as a dedicated hwmon channel config.
The driver can optionally provide the hwmon alarms for each sensor the
PVT controller supports. The alarms functionality is made compile-time
configurable due to the hardware interface implementation peculiarity,
which is connected with an ability to convert data from only one sensor
at a time. Additional limitation is that the controller performs the
thresholds checking synchronously with the data conversion procedure.
Due to these limitations in order to have the hwmon alarms
automatically detected the driver code must switch from one sensor to
another, read converted data and manually check the threshold status
bits. Depending on the measurements timeout settings this design may
cause additional burden on the system performance. By default if the
alarms kernel config is disabled the data conversion is performed by
the driver on demand when read operation is requested via corresponding
_input-file.

For hwmon drivers using the hwmon_device_register_with_info() API, it
is desirable to have a generic notification mechanism available. This
mechanism can be used to notify userspace as well as the thermal
subsystem if the driver experiences any events, such as warning or
critical alarms.
Implement hwmon_notify_event() to provide this mechanism. The function
generates a sysfs event and a udev event. If the device is registered
with the thermal subsystem and the event is associated with a temperature
sensor, also notify the thermal subsystem that a thermal event occurred.

<yibin.gong@nxp.com>:
There is ecspi ERR009165 on i.mx6/7 soc family, which cause FIFO
transfer to be send twice in DMA mode. Please get more information from:
https://www.nxp.com/docs/en/errata/IMX6DQCE.pdf. The workaround is adding
new sdma ram script which works in XCH mode as PIO inside sdma instead
of SMC mode, meanwhile, 'TX_THRESHOLD' should be 0. The issue should be
exist on all legacy i.mx6/7 soc family before i.mx6ul.
NXP fix this design issue from i.mx6ul, so newer chips including i.mx6ul/
6ull/6sll do not need this workaroud anymore. All other i.mx6/7/8 chips
still need this workaroud. This patch set add new 'fsl,imx6ul-ecspi'
for ecspi driver and 'ecspi_fixed' in sdma driver to choose if need errata
or not.
The first two reverted patches should be the same issue, though, it
seems 'fixed' by changing to other shp script. Hope Sean or Sascha could
have the chance to test this patch set if could fix their issues.
Besides, enable sdma support for i.mx8mm/8mq and fix ecspi1 not work
on i.mx8mm because the event id is zero.
PS:
Please get sdma firmware from below linux-firmware and copy it to your
local rootfs /lib/firmware/imx/sdma.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/imx/sdma
v2:
1.Add commit log for reverted patches.
2.Add comment for 'ecspi_fixed' in sdma driver.
3.Add 'fsl,imx6sll-ecspi' compatible instead of 'fsl,imx6ul-ecspi'
rather than remove.
v3:
1.Confirm with design team make sure ERR009165 fixed on i.mx6ul/i.mx6ull
/i.mx6sll, not fixed on i.mx8m/8mm and other i.mx6/7 legacy chips.
Correct dts related dts patch in v2.
2.Clean eratta information in binding doc and new 'tx_glitch_fixed' flag
in spi-imx driver to state ERR009165 fixed or not.
3.Enlarge burst size to fifo size for tx since tx_wml set to 0 in the
errata workaroud, thus improve performance as possible.
v4:
1.Add Ack tag from Mark and Vinod
2.Remove checking 'event_id1' zero as 'event_id0'.
v5:
1.Add the last patch for compatible with the current uart driver which
using rom script, so both uart ram script and rom script supported
in latest firmware, by default uart rom script used. UART driver
will be broken without this patch.
v6:
1.Resend after rebase the latest next branch.
2.Remove below No.13~No.15 patches of v5 because they were mergered.
ARM: dts: imx6ul: add dma support on ecspi
ARM: dts: imx6sll: correct sdma compatible
arm64: defconfig: Enable SDMA on i.mx8mq/8mm
3.Revert "dmaengine: imx-sdma: fix context cache" since
'context_loaded' removed.
v7:
1.Put the last patch 13/13 'Revert "dmaengine: imx-sdma: fix context
cache"' to the ahead of 03/13 'Revert "dmaengine: imx-sdma: refine
to load context only once" so that no building waring during comes out
during bisect.
2.Address Sascha's comments, including eliminating any i.mx6sx in this
series, adding new 'is_imx6ul_ecspi()' instead imx in imx51 and taking
care SMC bit for PIO.
3.Add back missing 'Reviewed-by' tag on 08/15(v5):09/13(v7)
'spi: imx: add new i.mx6ul compatible name in binding doc'
v8:
1.remove 0003-Revert-dmaengine-imx-sdma-fix-context-cache.patch and merge
it into 04/13 of v7
2.add 0005-spi-imx-fallback-to-PIO-if-dma-setup-failure.patch for no any
ecspi function broken even if sdma firmware not updated.
3.merge 'tx.dst_maxburst' changes in the two continous patches into one
patch to avoid confusion.
4.fix typo 'duplicated'.

Commit
987053a30016 ("efi/x86: Move command-line initrd loading to efi_main")
moved the command-line initrd loading into efi_main(), with a check
to ensure that it was attempted only if the EFI stub was booted via
efi_pe_entry rather than the EFI handover entry.
However, in the case where it was booted via handover entry, and thus an
initrd may have already been loaded by the bootloader, it then wrote 0
for the initrd address and size, removing any existing initrd.
Fix this by checking if size is positive before setting the fields in
the bootparams structure.

Marvell SDIO device ID 0x9134 is used in SDIO Common CIS (Card Information
Structure) and not in SDIO wlan function (with ID 1). SDIO Common CIS is
accessed by function ID 0.
So change this misleading macro name to SDIO_DEVICE_ID_MARVELL_8887_F0 as
it does not refer to wlan function. It refers to function 0.
Wlan module on this SDIO card is available at function ID 1 and is
identified by different SDIO device ID 0x9135. Kernel quirks for SDIO
devices are matched against device ID from SDIO Common CIS. Therefore
device ID used in quirk is correct, just has misleading name.

If the tmio device is attached to a genpd (PM domain), that genpd may have
->start|stop() callback assigned to it. To make sure the device is
accessible during ->probe(), genpd's ->start() callback must be invoked,
which is currently managed by tmio_mmc_host_probe(). However, it's likely
that may be too late for some cases, as registers may be read and written
way before that point.
To fix the behaviour, let's move the call to dev_pm_domain_start() from
tmio_mmc_host_probe() into those clients that needs it. From discussions at
linux-mmc mailing list, it turned out that it should be sufficient to do
this for the SDHI renesas variants, hence the call is move to
renesas_sdhi_probe().

Before calling tmio_mmc_host_probe(), the caller is required to enable
clocks for its device, as to make it accessible when reading/writing
registers during probe.
Therefore, the responsibility to disable these clocks, in the error path of
->probe() and during ->remove(), is better managed outside
tmio_mmc_host_remove(). As a matter of fact, callers of
tmio_mmc_host_remove() already expects this to be the behaviour.
However, there's a problem with tmio_mmc_host_remove() when the Kconfig
option, CONFIG_PM, is set. More precisely, tmio_mmc_host_remove() may then
disable the clock via runtime PM, which leads to clock enable/disable
imbalance problems, when the caller of tmio_mmc_host_remove() also tries to
disable the same clocks.
To solve the problem, let's make sure tmio_mmc_host_remove() leaves the
device with clocks enabled, but also make sure to disable the IRQs, as we
normally do at ->runtime_suspend().

This driver has been developed as a separate module starting
from the similar sdhci-esdhc-imx.c.
Reasons for a separate sdchi-esdhc-mcf driver:
- m68K architecture does not support devicetrees, so modifying
sdhci-of-esdhc.c that is devicetree-related adding platform data
seems not appropriate,
- clock-related part, has to be implemented specifically for
mcf5441x family (see esdhc_mcf_pltfm_set_clock()),
- this is a big endian cpu accessing a big endian controller,
but about sdma, this controller does not support hw swap, which
needs to be handled with specific code,
- some other minor differences but mainly to avoid risks on
tweaking inside largely used imx driver. Adding just a small
size ColdFire-specific driver, with benefits in a further less
risky maintenance.

Some controller as the ColdFire eshdc may require an endianness
byte swap, because DMA read endianness is not configurable.
Facilitate using the bounce buffer for this by adding
->copy_to_bounce_buffer().

Kbuild test robot reports the following warning in lines 56 and 87 of
drivers/mmc/host/meson-mx-sdhc-clkc.c:
Using plain integer as NULL pointer
Drop the integer value from the struct initialization to fix that
warning. This will still ensure that the compiler will zero out the
struct so it's in a well-defined state.

For Meson8 and Meson8b SoCs the vendor driver follows the following
pattern:
- for eMMC and SD cards in .set_pdma it sets:
pdma->rxfifo_manual_flush = 1;
- for SDIO cards in .set_pdma it sets:
pdma->rxfifo_manual_flush = 0;
- before syncing the DMA read buffer is sets:
pdma->rxfifo_manual_flush |= 0x02;
Set the second bit of MESON_SDHC_PDMA_RXFIFO_MANUAL_FLUSH without
clearing the first bit before syncing the DMA read buffer. This fixes a
problem where Meson8 and Meson8b SoCs would read random garbage from SD
cards. It is not clear why it worked for eMMC cards. This manifested in
the following errors when plugging in an SD card:
unrecognised SCR structure version <random number>
