The Marvell CN10K DRAM Subsystem (DSS) performance monitor is only

The bug is here:
return cluster;
The list iterator value 'cluster' will *always* be set and non-NULL
by list_for_each_entry(), so it is incorrect to assume that the
iterator value will be NULL if the list is empty or no element
is found.
To fix the bug, return 'cluster' when found, otherwise return NULL.

According to the datasheet, mt7622 only has 5 ECC capabilities instead
of 7, and the decoding error register is arranged as follows:
+------+---------+---------+---------+---------+
| Bits | 19:15 | 14:10 | 9:5 | 4:0 |
+------+---------+---------+---------+---------+
| Name | ERRNUM3 | ERRNUM2 | ERRNUM1 | ERRNUM0 |
+------+---------+---------+---------+---------+
This means err_mask should be 0x1f instead of 0x3f and the number of
bits shifted in mtk_ecc_get_stats should be 5 instead of 8.
This commit introduces err_shift for the difference in this register
and fix other existing parameters.
Public MT7622 reference manual can be found on [0] and the info this
commit is based on is from page 656 and page 660.

The below commit changed types of some hooks in struct psc_ops. It also
changed the types of the functions which are referenced in the instances
of the above struct.
However the commit did so only for CONFIG_PPC_MPC52xx, but not for
CONFIG_PPC_MPC512x. This results in build errors like:
mpc52xx_uart.c:static unsigned int mpc52xx_psc_raw_tx_rdy(struct uart_port *port)
mpc52xx_uart.c:static int mpc512x_psc_raw_tx_rdy(struct uart_port *port)
^^^
mpc52xx_uart.c:static int mpc5125_psc_raw_tx_rdy(struct uart_port *port)
^^^
Therefore, fix the latter case now too.

There are four possible gain values according to 'sx9324_gain_vals[]':
1, 2, 4, and 8
The values are off by one when writing and reading the register. The
bits should be set according to this equation:
ilog2(<gain>) + 1
so that a gain of 8 is 0x4 in the register field and a gain of 4 is 0x3
in the register field, etc. Note that a gain of 0 is reserved per the
datasheet. The default gain (SX9324_REG_PROX_CTRL0_GAIN_1) is also
wrong. It should be 0x1 << 3, i.e. 0x8, not 0x80 which is setting the
reserved bit 7.
Fix this all up to properly handle the hardware gain and return errors
for invalid settings.

After commit 7a3605bef878 ("iio: sx9310: Support ACPI property") we
started using the 'indio_dev->dev' to extract device properties for
various register settings in sx9310_get_default_reg(). This broke DT
based systems because dev_fwnode() used in the device_property*() APIs
can't find an 'of_node'. That's because the 'indio_dev->dev.of_node'
pointer isn't set until iio_device_register() is called. Set the pointer
earlier, next to where the ACPI companion is set, so that the device
property APIs work on DT systems.

When matching an OF device, the match mechanism tries all components of
the compatible property. This can result with a device matched with a
compatible string that isn't the first in the compatible list. For
instance, with a compatible property set to
compatible = "ti,dac081c081", "ti,dac5571";
the driver will match the second compatible string, as the first one
isn't listed in the of_device_id table. The device will however be named
"dac081c081" by the I2C core.
This causes an issue when identifying the chip. The probe function
receives a i2c_device_id that comes from the module's I2C device ID
table. There is no entry in that table for "dac081c081", which results
in a NULL pointer passed to the probe function.
To fix this, add chip_id information in the data field of the OF device
ID table, and retrieve it with device_get_match_data() for OF
devices.

As per Table 130 of the wm8994 datasheet at [1], there is an off-on
delay for LDO1 and LDO2. In the wm8958 datasheet [2], I could not
find any reference to it. I could not find a wm1811 datasheet to
double-check there, but as no one has complained presumably it works
without it.
This solves the issue on Samsung Aries boards with a wm8994 where
register writes fail when the device is powered off and back-on
quickly.

This commit corrects the printing of the IPU clock error percentage if
it is between -0.1% to -0.9%. For example, if the pixel clock requested
is 27.2 MHz but only 27.0 MHz can be achieved the deviation is -0.8%.
But the fixed point math had a flaw and calculated error of 0.2%.
Before:
Clocks: IPU 270000000Hz DI 24716667Hz Needed 27200000Hz
IPU clock can give 27000000 with divider 10, error 0.2%

On SCMI transports whose channels are based on a shared resource the TX
channel area has to be acquired by the agent before placing the desired
command into the channel and it will be then relinquished by the platform
once the related reply has been made available into the channel.
On an RX channel the logic is reversed with the platform acquiring the
channel area and the agent reliquishing it once done by calling the
scmi_clear_channel() helper.
As a consequence, even in case of error, the agent must never try to clear
a TX channel from its side: restrict the existing clear channel call on the
the reply path only to delayed responses since they are indeed coming from
the RX channel.

On QCOM platforms with EPSS flavour of cpufreq IP a throttled frequency is
obtained from another register REG_DOMAIN_STATE, thus the helper function
qcom_lmh_get_throttle_freq() should be modified accordingly, as for now
it returns gibberish since .reg_current_vote is unset for EPSS hardware.
To exclude a hardcoded magic number 19200 it is replaced by "xo" clock rate
in KHz.

The qcom_lmh_dcvs_notify() will get the dev_pm_opp instance for
throttling, but will not put it, ending up with leaking a reference
count and the following backtrace when putting the CPU offline.
Correctly put the reference count of the returned opp instance.

The driver would disable the worker when cpu is being put offline, but
it happens closer to the end of cpufreq_offline(). The function
qcom_lmh_dcvs_poll() can be running in parallel with this, when
policy->cpus already has been updated. Read policy->related_cpus
instead.

Samsung' 840 EVO with the latest firmware (EXT0DB6Q) locks up with
the a message: "READ LOG DMA EXT failed, trying PIO" during boot.
Initially this was discovered because it caused a crash
with the sata_dwc_460ex controller on a WD MyBook Live DUO.
The reporter "Tice Rex" which has the unique opportunity that he
has two Samsung 840 EVO SSD! One with the older firmware "EXT0BB0Q"
which booted fine and didn't expose "READ LOG DMA EXT". But the
newer/latest firmware "EXT0DB6Q" caused the headaches.

the driver uses libata's "tag" values from in various arrays.
Since the mentioned patch bumped the ATA_TAG_INTERNAL to 32,
the value of the SATA_DWC_QCMD_MAX needs to account for that.
Otherwise ATA_TAG_INTERNAL usage cause similar crashes like
this as reported by Tice Rex on the OpenWrt Forum and
reproduced (with symbols) here:

This is because sata_dwc_dma_xfer_complete() NULLs the
dma_pending's next neighbour "chan" (a *dma_chan struct) in
this '32' case right here (line ~735):
> hsdevp->dma_pending[tag] = SATA_DWC_DMA_PENDING_NONE;
Then the next time, a dma gets issued; dma_dwc_xfer_setup() passes
the NULL'd hsdevp->chan to the dmaengine_slave_config() which then
causes the crash.
With this patch, SATA_DWC_QCMD_MAX is now set to ATA_MAX_QUEUE + 1.
This avoids the OOB. But please note, there was a worthwhile discussion
on what ATA_TAG_INTERNAL and ATA_MAX_QUEUE is. And why there should not
be a "fake" 33 command-long queue size.
Ideally, the dw driver should account for the ATA_TAG_INTERNAL.
In Damien Le Moal's words: "... having looked at the driver, it
is a bigger change than just faking a 33rd "tag" that is in fact
not a command tag at all."

This reverts commit 7dabfa2bc4803eed83d6f22bd6f045495f40636b. There are

expected. Let's revert it out for now so that -rc1 boots.

In commit 9cbadf094d9d ("net: stmmac: support max-speed device tree
property"), when DT platforms don't set "max-speed", max_speed is set to
-1; for non-DT platforms, it stays the default 0.
Prior to commit eeef2f6b9f6e ("net: stmmac: Start adding phylink support"),
the check for a valid max_speed setting was to check if it was greater
than zero. This commit got it right, but subsequent patches just checked
for non-zero, which is incorrect for DT platforms.
In commit 92c3807b9ac3 ("net: stmmac: convert to phylink_get_linkmodes()")
the conversion switched completely to checking for non-zero value as a
valid value, which caused 1000base-T to stop getting advertised by
default.
Instead of trying to fix all the checks, simply leave max_speed alone if
DT property parsing fails.

32b builds with CONFIG_PHYS_ADDR_T_64BIT=y, such as i386 PAE,
raise a linker error due to a 64b division:
ld: drivers/net/ethernet/fungible/funcore/fun_dev.o: in function
`fun_dev_enable':
(.text+0xe1a): undefined reference to `__udivdi3'
The divisor in the offendinng expression is a power of 2. Change it to
use an explicit right shift.
