Raydium USB touchscreen fails to set config if LPM is enabled:

[ 2.030659] usb 1-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0

[ 7.132209] usb 1-8: can't set config #1, error -110
Same behavior can be observed on 2386:3114.
Raydium claims the touchscreen supports LPM under Windows, so I used
Microsoft USB Test Tools (MUTT) [1] to check its LPM status. MUTT shows
that the LPM doesn't work under Windows, either. So let's just disable LPM
for Raydium touchscreens.

Devices connected under Terminus Technology Inc. Hub (1a40:0101) may

Some expirements indicate that the USB devices connected to the hub are
innocent, it's the hub itself is to blame. The hub needs extra delay
time after it resets its port.
Hence wait for extra delay, if the device is connected to this quirky
hub.

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-fixes
Three regressions
- Revert frame counter support
. This patch fixes a issue which doesn't work extension and clone
mode because some CRTC devices don't provide frame counter value
properly.
- Fix lack of fbdev on Rinato and trats boards.
. This patch considers for connector to be registered by DSI after
DRM device is registered, and also it makes fbdev initializaion
to be done even if no connector at the moment.
- Check for dsi->panel object correctly
. This patch fixes checking for dsi->panel. of_drm_find_panel
function returns panel object or error value so error value
should be checked using IS_ERR macro.

The timecounter needs to be updated at least once per ~550 seconds in
order to avoid a 40-bit SYSTIM timestamp to be misinterpreted as an old
timestamp.
Since commit 500462a9de65 ("timers: Switch to a non-cascading wheel"),
scheduling of delayed work seems to be less accurate and a requested
delay of 540 seconds may actually be longer than 550 seconds. Also, the
PHC may be adjusted to run up to 6% faster than real time and the system
clock up to 10% slower. Shorten the delay to 360 seconds to be sure the
timecounter is updated in time.
This fixes an issue with HW timestamps on 82580/I350/I354 being off by
~1100 seconds for few seconds every ~9 minutes.

Currently if the driver does a TSO offload the bytecount sent to
netdev_tx_sent_queue will be incorrect. This is because in ice_tso we
overwrite the initial value that we set in ice_tx_map. This creates a
mismatch between the Tx and Tx clean flow. In the Tx clean flow we
calculate the bytecount (called total_bytes) as we clean the
descriptors so the value used in the Tx clean path is correct. Fix this
by using += in ice_tso instead of =. This fixes the mismatch in
bytecount mentioned above.

Prior to this commit the driver was running into tx_timeouts when a
queue was stressed enough. This was happening because the HW tail
and SW tail (NTU) were incorrectly out of sync. Consequently this was
causing the HW head to collide with the HW tail, which to the hardware
means that all descriptors posted for Tx have been processed.
Due to the Tx logic used in the driver SW tail and HW tail are allowed
to be out of sync. This is done as an optimization because it allows the
driver to write HW tail as infrequently as possible, while still
updating the SW tail index to keep track. However, there are situations
where this results in the tail never getting updated, resulting in Tx
timeouts.
Tx HW tail write condition:
if (netif_xmit_stopped(txring_txq(tx_ring) || !skb->xmit_more)
writel(sw_tail, tx_ring->tail);
An issue was found in the Tx logic that was causing the afore mentioned
condition for updating HW tail to never happen, causing tx_timeouts.
In ice_xmit_frame_ring we calculate how many descriptors we need for the
Tx transaction based on the skb the kernel hands us. This is then passed
into ice_maybe_stop_tx along with some extra padding to determine if we
have enough descriptors available for this transaction. If we don't then
we return -EBUSY to the stack, otherwise we move on and eventually
prepare the Tx descriptors accordingly in ice_tx_map and set
next_to_watch. In ice_tx_map we make another call to ice_maybe_stop_tx
with a value of MAX_SKB_FRAGS + 4. The key here is that this value is
possibly less than the value we sent in the first call to
ice_maybe_stop_tx in ice_xmit_frame_ring. Now, if the number of unused
descriptors is between MAX_SKB_FRAGS + 4 and the value used in the first
call to ice_maybe_stop_tx in ice_xmit_frame_ring then we do not update
the HW tail because of the "Tx HW tail write condition" above. This is
because in ice_maybe_stop_tx we return success from ice_maybe_stop_tx
instead of calling __ice_maybe_stop_tx and subsequently calling
netif_stop_subqueue, which sets the __QUEUE_STATE_DEV_XOFF bit. This
bit is then checked in the "Tx HW tail write condition" by calling
netif_xmit_stopped and subsequently updating HW tail if the
afore mentioned bit is set.
In ice_clean_tx_irq, if next_to_watch is not NULL, we end up cleaning
the descriptors that HW sets the DD bit on and we have the budget. The
HW head will eventually run into the HW tail in response to the
description in the paragraph above.
The next time through ice_xmit_frame_ring we make the initial call to
ice_maybe_stop_tx with another skb from the stack. This time we do not
have enough descriptors available and we return NETDEV_TX_BUSY to the
stack and end up setting next_to_watch to NULL.
This is where we are stuck. In ice_clean_tx_irq we never clean anything
because next_to_watch is always NULL and in ice_xmit_frame_ring we never
update HW tail because we already return NETDEV_TX_BUSY to the stack and
eventually we hit a tx_timeout.
This issue was fixed by making sure that the second call to
ice_maybe_stop_tx in ice_tx_map is passed a value that is >= the value
that was used on the initial call to ice_maybe_stop_tx in
ice_xmit_frame_ring. This was done by adding the following defines to
make the logic more clear and to reduce the chance of mucking this up
again:
ICE_CACHE_LINE_BYTES 64
ICE_DESCS_PER_CACHE_LINE (ICE_CACHE_LINE_BYTES / \
sizeof(struct ice_tx_desc))
ICE_DESCS_FOR_CTX_DESC 1
ICE_DESCS_FOR_SKB_DATA_PTR 1
The ICE_CACHE_LINE_BYTES being 64 is an assumption being made so we
don't have to figure this out on every pass through the Tx path. Instead
I added a sanity check in ice_probe to verify cache line size and print
a message if it's not 64 Bytes. This will make it easier to file issues
if they are seen when the cache line size is not 64 Bytes when reading
from the GLPCI_CNF2 register.

This patch allows users to enable/disable internal TX and/or RX clock
delay for BCM54616S PHYs so as to satisfy RGMII timing specifications.
On a particular platform, whether TX and/or RX clock delay is required
depends on how PHY connected to the MAC IP. This requirement can be
specified through "phy-mode" property in the platform device tree.
The patch is inspired by commit 733336262b28 ("net: phy: Allow BCM5481x

The NFIT machine check handler uses the physical address from the mce
structure, and compares it against information in the ACPI NFIT table
to determine whether that location lies on an NVDIMM. The mce->addr
field however may not always be valid, and this is indicated by the
MCI_STATUS_ADDRV bit in the status field.
Export mce_usable_address() which already performs validation for the
address, and use it in the NFIT handler.
