If there are more scatter entries than the recommended limit provided by
the ib device, UMR registration is used. This will provide optimal
performance when performing large RDMA READs over devices that advertise
the threshold capability.

Read the PHY-specific status register for the current operating mode
(speed and duplex) of the PHY. This register reflects the actual
mode that the PHY has resolved depending on either the advertisements
of autoneg is enabled, or the forced mode if autoneg is disabled.
This ensures that phylib's software state always tracks the hardware
state.
It seems both AR8033 (which uses the AR8031 ID) and AR8035 support
this status register. AR8030 is not known at the present time.
This patch depends on "net: phy: extract pause mode" and "net: phy:
extract link partner advertisement reading".

When userspace writes to the MII_ADVERTISE register, we update phylib's
advertising mask and trigger a renegotiation. However, writing to the
MII_CTRL1000 register, which contains the gigabit advertisement, does
neither. This can lead to phylib's copy of the advertisement becoming
de-synced with the values in the PHY register set, which can result in
incorrect negotiation resolution.

mdio_device_reset() makes use of the atomic-pretending API flavor for
handling the PHY reset GPIO line.
I found no hint that mdio_device_reset() is called from atomic context
and indeed it uses usleep_range() since long time, so I would assume that
it is OK to sleep there.
This patch switch to gpiod_set_value_cansleep() in mdio_device_reset().
This is relevant if e.g. the PHY reset line is tied to a I2C GPIO
controller.
This has been tested on a ZynqMP board running an upstream 4.19 kernel and
then hand-ported on current kernel tree.

r8152 may fail to establish network connection after resume from system
suspend.
If the USB port connects to r8152 lost its power during system suspend,
the MAC address was written before is lost. The reason is that The MAC
address doesn't get written again in its reset_resume callback.
So let's set MAC address again in reset_resume callback. Also remove
unnecessary lock as no other locking attempt will happen during
reset_resume.

This reverts commit 4eaceea3a00f8e936a7f48dcd0c975a57f88930f.
Several userspace clients (modesetting ddx and mutter+wayland at least)
handle encoder.possible_crtcs incorrectly. What they essentially do is
the following:
possible_crtcs = ~0;
for_each_possible_encoder(connector)
possible_crtcs &= encoder->possible_crtcs;
Ie. they calculate the intersection of the possible_crtcs
for the connector when they really should be calculating the
union instead.
In our case each MST encoder now has just one unique bit set,
and so the intersection is always zero. The end result is that
MST connectors can't be lit up because no crtc can be found to
drive them.
I've submitted a fix for the modesetting ddx [1], and complained
on #wayland about mutter, so hopefully the situation will improve
in the future. In the meantime we have regression, and so must go
back to the old way of misconfiguring possible_crtcs in the kernel.

Fixes for omaps for v5.4-rc cycle
Here are fixes for omaps to deal with few regressions, and to fix
more boot time errors and warnings:
- The recent ti-sysc interconnect target module driver changes had
incorrect clock bits for both clocks and dts that cause warnings
- For omap3-gta04, gpio changes caused the LCD to break a while back,
and after discussing things the right fix is to set spi-cs-high
- Recent omapdrm changes to use generic panels caused tfp410 to be
disabled as we now must enable the generic support for it in
defconfig
- Recent omapdrm and backlight changes also finally made droid4 LCD
to work, so let's enable it in the defconfig it can be used out
of the box. This is not strictly a fix, but we still also have the
older CONFIG_MFD_TI_LMU options available so this cuts down the
confusion for trying to guess which display and which backlight
is needed
- Recent ti-sysc interconnect target module changes need the gpio
module disabled on some boards, but this now needs to happen at
the module level, not at the gpio driver level
- Recent changes to probe system timers with ti-sysc caused warnings
about mismatch in syconfig registers, so let's configure the option
for RESET_STATUS as available in the TRMs
- Recent changes to probe LCDC with ti-sysc caused warnings about
mismatch in sysconfig registers, so let's configure the missing
idlemodes for both platform data and dts as documented in TRMs
- Since we moved mach-omap2 to probe with device tree, we've been
getting voltage controller warnings. Turns out this code is no
longer needed, so let's just remove omap2_set_init_voltage() to
get rid of the pointless warnings
- Configure am4372 dispc memory bandwidth to avoid underflow errors

The OMAP36xx and AM/DM37x TRMs say that the maximum divider for DSS fclk
(in CM_CLKSEL_DSS) is 32. Experimentation shows that this is not
correct, and using divider of 32 breaks DSS with a flood or underflows
and sync losts. Dividers up to 31 seem to work fine.
There is another patch to the DT files to limit the divider correctly,
but as the DSS driver also needs to know the maximum divider to be able
to iteratively find good rates, we also need to do the fix in the DSS
driver.

I forgot to update the g4x sprite scaling stride check when GTT
remapping was introduced. The stride of the original framebuffer
is irrelevant when remapping is used and instead we want to check
the stride of the remapped view.
Also drop the duplicate width_bytes check. We already check that
a few lines earlier.

There was a integer wraparound when mode_clock became too high,
and we didn't correct for the FEC overhead factor when dividing,
with the calculations breaking at HBR3.
As a result our calculated bpp was way too high, and the link width
limitation never came into effect.
Print out the resulting bpp calcululations as a sanity check, just
in case we ever have to debug it later on again.
We also used the wrong factor for FEC. While bspec mentions 2.4%,
all the calculations use 1/0.972261, and the same ratio should be
applied to data M/N as well, so use it there when FEC is enabled.
This fixes the FIFO underrun we are seeing with FEC enabled.
Changes since v2:
- Handle fec_enable in intel_link_compute_m_n, so only data M/N is adjusted. (Ville)
- Fix initial hardware readout for FEC. (Ville)
Changes since v3:
- Remove bogus fec_to_mode_clock. (Ville)
Changes since v4:
- Use the correct register for icl. (Ville)
- Split hw readout to a separate patch.

The stmmac driver will try to acquire its private mutex during suspend
via phylink_resolve() -> stmmac_mac_link_down() -> stmmac_eee_init().
However, the phylink configuration is updated with the private mutex
held already, which causes a deadlock during suspend.
Fix this by moving the phylink configuration updates out of the region
of code protected by the private mutex.

Randy Dunlap reports on the sparse list that sparse warns about this
expression:
of_irq->percpu ? free_percpu_irq(of_irq->irq, clkevt) :
free_irq(of_irq->irq, clkevt);
and honestly, sparse is correct to warn. The return type of
free_percpu_irq() is 'void', while free_irq() returns a 'const void *'
that is the devname argument passed in to the request_irq().
You can't mix a void type with a non-void types in a conditional
expression according to the C standard. It so happens that gcc seems to
accept it - and the resulting type of the expression is void - but
there's really no reason for the kernel to have this kind of
non-standard expression with no real upside.
The natural way to write that expression is with an if-statement:
if (of_irq->percpu)
free_percpu_irq(of_irq->irq, clkevt);
else
free_irq(of_irq->irq, clkevt);
which is more legible anyway.
I'm not sure why that timer-of code seems to have this odd pattern. It
does the same at allocation time, but at least there the types match,
and it makes sense as an expression.

[ 41.729860] BUG: scheduling while atomic: ptp4l/208/0x00000002
[ 41.735682] INFO: lockdep is turned off.
Enabling RX timestamping will logically disturb the fastpath (processing
of meta frames). Replace bool hwts_rx_en with a bit that is checked
atomically from the fastpath and temporarily unset from the sleepable
context during a change of the RX timestamping process (a destructive
operation anyways, requires switch reset).
If found unset, the fastpath (net/dsa/tag_sja1105.c) will just drop any
received meta frame and not take the meta_lock at all.
Fixes: a602afd200f5 ("net: dsa: sja1105: Expose PTP timestamping ioctls to userspace")
