As of commit b9ddd5091160793e ("iio: adc: max9611: Fix temperature
reading in probe"), max9611 initialization sometimes fails on the
Salvator-X(S) development board with:
max9611 4-007f: Invalid value received from ADC 0x8000: aborting
max9611: probe of 4-007f failed with error -5
The max9611 driver tests communications with the chip by reading the die
temperature during the probe function, which returns an invalid value.
According to the datasheet, the typical ADC conversion time is 2 ms, but
no minimum or maximum values are provided. Maxim Technical Support
confirmed this was tested with temperature Ta=25 degreeC, and promised
to inform me if a maximum/minimum value is available (they didn't get
back to me, so I assume it is not).
However, the driver assumes a 1 ms conversion time. Usually the
usleep_range() call returns after more than 1.8 ms, hence it succeeds.
When it returns earlier, the data register may be read too early, and
the previous measurement value will be returned. After boot, this is
the temperature POR (power-on reset) value, causing the failure above.
Fix this by increasing the delay from 1000-2000 µs to 3000-3300 µs.
Note that this issue has always been present, but it was exposed by the
aformentioned commit.

Each time we need to read a sample (from the sysfs interface, since the
driver supports only it) the driver writes the configuration register
with the proper settings needed to perform the said read, then it runs
another xfer to actually read the resulting value. Most notably the
configuration register is updated to set the ADC internal MUX depending by
which channel the read targets.
Unfortunately this seems not enough to ensure correct operation because
the ADC works in a pipelined-like fashion and the new configuration isn't
applied in time.
The ADC alternates two phases: acquisition and conversion. During the
acquisition phase the ADC samples the analog signal in an internal
capacitor; in the conversion phase the ADC performs the actual analog to
digital conversion of the stored voltage. Note that of course the MUX
needs to be set to the proper channel when the acquisition phase is
performed.
Once the conversion phase has been completed, the device automatically
switches back to a new acquisition; on the other hand the device switches
from acquisition to conversion on the rising edge of SPI cs signal (that
is when the xfer finishes).
Only after both two phases have been completed (with the proper settings
already written in the configuration register since the beginning) it is
possible to read the outcome from SPI bus.
With the current driver implementation, we end up in the following
situation:
_______ 1st xfer ____________ 2nd xfer ___________________
SPI cs.. \_________/ \_________/
SPI rd.. idle |(val N-2)+ idle | val N-1 + idle ...
SPI wr.. idle | cfg N + idle | (X) + idle ...
------------------------ + -------------------- + ------------------
AD .. acq N-1 + cnv N-1 | acq N + cnv N | acq N+1
As shown in the diagram above, the value we read in the Nth read belongs
to configuration setting N-1.
In case the configuration is not changed (config[N] == config[N-1]), then
we still get correct data, but in case the configuration changes (i.e.
switching the MUX on another channel), we get wrong data (data from the
previously selected channel).
This patch fixes this by performing one more "dummy" transfer in order to
ending up in reading the data when it's really ready, as per the following
timing diagram.
_______ 1st xfer ____________ 2nd xfer ___________ 3rd xfer ___
SPI cs.. \_________/ \_________/ \_________/
SPI rd.. idle |(val N-2)+ idle |(val N-1)+ idle | val N + ..
SPI wr.. idle | cfg N + idle | (X) + idle | (X) + ..
------------------------ + -------------------- + ------------------- + --
AD .. acq N-1 + cnv N-1 | acq N + cnv N | acq N+1 | ..
NOTE: in the latter case (cfg changes), the acquisition phase for the
value to be read begins after the 1st xfer, that is after the read request
has been issued on sysfs. On the other hand, if the cfg doesn't change,
then we can refer to the fist diagram assuming N == (N - 1); the
acquisition phase _begins_ before the 1st xfer (potentially a lot of time
before the read has been issued via sysfs, but it _ends_ after the 1st
xfer, that is _after_ the read has started. This should guarantee a
reasonably fresh data, which value represents the voltage that the sampled
signal has after the read start or maybe just around it.

When commit:
69c1f396f25b ("efi/x86: Convert x86 EFI earlyprintk into generic earlycon implementation")
moved the x86 specific EFI earlyprintk implementation to a shared location,
it also tweaked the behaviour. In particular, it dropped a trick with full
framebuffer remapping after page initialization, leading to two regressions:
1) very slow scrolling after page initialization,
2) kernel hang when the 'keep_bootcon' command line argument is passed.
Putting the tweak back fixes #2 and mitigates #1, i.e., it limits the slow
behavior to the early boot stages, presumably due to eliminating heavy
map()/unmap() operations per each pixel line on the screen.

We don't actually need to call query_mode() in order to obtain the

gop->mode->info, so just access it directly in the setup_gop32/64()

Also nothing uses the size of the info structure, so don't update the

Memory regions that are reserved using efi_mem_reserve_persistent()
are recorded in a special EFI config table which survives kexec,
allowing the incoming kernel to honour them as well. However,
such reservations are not visible in /proc/iomem, and so the kexec
tools that load the incoming kernel and its initrd into memory may
overwrite these reserved regions before the incoming kernel has a
chance to reserve them from further use.
Address this problem by adding these reservations to /proc/iomem as
they are created. Note that reservations that are inherited from a
previous kernel are memblock_reserve()'d early on, so they are already
visible in /proc/iomem.

When suspending, and there is still CAN traffic on the interfaces the
flexcan immediately wakes the platform again. As it should :-). But it
throws this error msg:
[ 3169.378661] PM: noirq suspend of devices failed
On the way down to suspend the interface that throws the error message
calls flexcan_suspend() but fails to call flexcan_noirq_suspend(). That
means flexcan_enter_stop_mode() is called, but on the way out of suspend
the driver only calls flexcan_resume() and skips flexcan_noirq_resume(),
thus it doesn't call flexcan_exit_stop_mode(). This leaves the flexcan
in stop mode, and with the current driver it can't recover from this
even with a soft reboot, it requires a hard reboot.
This patch fixes the deadlock when using self wakeup, by calling
flexcan_exit_stop_mode() from flexcan_resume() instead of
flexcan_noirq_resume().
This also fixes another issue: CAN frames are received out-of-order in
first IRQ handler run after wakeup.
The problem is that the wakeup latency from frame reception to the IRQ
handler (where the CAN frames are sorted by timestamp) is much bigger
than the time stamp counter wrap around time. This means it's
impossible to sort the CAN frames by timestamp.
The reason is that the controller exits stop mode during noirq resume,
which means it receives frames immediately, but interrupt handling is
still not possible.
So exit stop mode during resume stage instead of noirq resume fixes this
issue.

When we receive a new packet from the guest, we check if the
src_cid is correct, but we forgot to check the dst_cid.
The host should accept only packets where dst_cid is
equal to the host CID.

The commit ef87f7da6b28 ("net: phy: dp83867: move dt parsing to probe")
causes regression on TI dra71x-evm and dra72x-evm, where DP83867 PHY is
used in "rgmii-id" mode - the networking stops working.
Unfortunately, it's not enough to just move DT parsing code to .probe() as
it depends on phydev->interface value, which is set to correct value abter
the .probe() is completed and before calling .config_init(). So, RGMII
configuration can't be loaded from DT.
To fix and issue
- move RGMII validation code to .config_init()
- parse RGMII parameters in dp83867_of_init(), but consider them as
optional.

Now RX interrupt is triggered twice every time, because in
cpsw_rx_interrupt() it is asked first and then disabled. So there will be
pending interrupt always, when RX interrupt is enabled again in NAPI
handler.
Fix it by first disabling IRQ and then do ask.

We may have found a bug in the nxp/lpc_eth.c driver. The function
platform_set_drvdata() is called twice, the second time it is called,
in lpc_mii_init(), it overwrites the struct net_device which should be
at pdev->dev->driver_data with pldat->mii_bus. When trying to remove
the driver, in lpc_eth_drv_remove(), platform_get_drvdata() will
return the pldat->mii_bus pointer and try to use it as a struct
net_device pointer. This causes unregister_netdev to segfault and
generate a kernel BUG. Is this reproducible?

Refer to the databook of DesignWare Cores Ethernet MAC Universal:
6.2.1.5 Register 4 (Transmit Descriptor List Address Register
If this register is not changed when the ST bit is set to 0, then
the DMA takes the descriptor address where it was stopped earlier.
The stmmac_tx_err() does zero indices to Tx descriptors, but does
not reset HW current Tx descriptor address. To fix inconsistency,
the base address of the Tx descriptors should be rewritten before
restarting Tx.

The EEE support has not been enabled on ENETC, but it may connect
to a PHY which supports EEE and advertises EEE by default, while
its link partner also advertises EEE. If this happens, the PHY enters
low power mode when the traffic rate is low and causes packet loss.
This patch disables EEE advertisement by default for any PHY that
ENETC connects to, to prevent the above unwanted outcome.
