[ Upstream commit 90ae47215de3fec862aeb1a0f0e28bb505ab1351 ]
Add more generic compatible string 'marvell,armada-3700-rwtm-firmware' for
this driver, since it can also be used on other Armada 3720 devices.
Current compatible string 'cznic,turris-mox-rwtm' is kept for backward
compatibility.

[ Upstream commit 5e5c9f9a75fc4532980c2e699caf8a36070a3a2e ]
Zone device is enabled after thermal_zone_of_sensor_register() completion,
but it's not disabled before senor is unregistered, leaving temperature
polling active. This results in accessing a disabled zone device and
produces a warning about this problem. Stop zone device before
unregistering it in order to fix this "use-after-free" problem.

[ Upstream commit 49da96d77938db21864dae6b7736b71e96c1d203 ]
Offlining a SATA device connected to a hisi SAS controller and then
scanning the host will result in detecting 255 non-existent devices:
# lsscsi
[2:0:0:0] disk ATA Samsung SSD 860 2B6Q /dev/sda
[2:0:1:0] disk ATA WDC WD2003FYYS-3 1D01 /dev/sdb
[2:0:2:0] disk SEAGATE ST600MM0006 B001 /dev/sdc
# echo "offline" > /sys/block/sdb/device/state
# echo "- - -" > /sys/class/scsi_host/host2/scan
# lsscsi
[2:0:0:0] disk ATA Samsung SSD 860 2B6Q /dev/sda
[2:0:1:0] disk ATA WDC WD2003FYYS-3 1D01 /dev/sdb
[2:0:1:1] disk ATA WDC WD2003FYYS-3 1D01 /dev/sdh
...
[2:0:1:255] disk ATA WDC WD2003FYYS-3 1D01 /dev/sdjb
After a REPORT LUN command issued to the offline device fails, the SCSI
midlayer tries to do a sequential scan of all devices whose LUN number is
not 0. However, SATA does not support LUN numbers at all.
Introduce a generic sas_slave_alloc() handler which will return -ENXIO for
SATA devices if the requested LUN number is larger than 0 and make libsas
drivers use this function as their .slave_alloc callback.

[ Upstream commit 332a9dd1d86f1e7203fc7f0fd7e82f0b304200fe ]
The shifting of the u8 integer returned fom ahc_inb(ahc, port+3) by 24 bits
to the left will be promoted to a 32 bit signed int and then sign-extended
to a u64. In the event that the top bit of the u8 is set then all then all
the upper 32 bits of the u64 end up as also being set because of the
sign-extension. Fix this by casting the u8 values to a u64 before the 24
bit left shift.

[ Upstream commit 742b0d7e15c333303daad4856de0764f4bc83601 ]
Interrupt line can be configured on different hardware in different way,
even inverted. Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.
The Maxim 77686 datasheet describes the interrupt line as active low
with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.
The interrupt line is shared between PMIC and RTC driver, so using level
sensitive interrupt is here especially important to avoid races. With
an edge configuration in case if first PMIC signals interrupt followed
shortly after by the RTC, the interrupt might not be yet cleared/acked
thus the second one would not be noticed.

[ Upstream commit 4d57fd9aeaa013a245bf1fade81e2c30a5efd491 ]
MODULE_DEVICE_TABLE is used to extract the device information out of the
driver and builds a table when being compiled. If using this macro,
kernel can find the driver if available when the device is plugged in,
and then loads that driver and initializes the device.

[ Upstream commit 0cb7af474e0dbb2f500c67aa62b6db9fafa74de2 ]
During an async commands execution the Rx buffer length is at first set
to max_msg_sz when the synchronous part of the command is first sent.
However once the synchronous part completes the transport layer waits
for the delayed response which will be processed using the same xfer
descriptor initially allocated. Since synchronous response received at
the end of the xfer will shrink the Rx buffer length to the effective
payload response length, it needs to be reset again.
Raise the Rx buffer length again to max_msg_sz before fetching the
delayed response to ensure full response is read correctly from the
shared memory.

[ Upstream commit 54b909436ede47e0ee07f1765da27ec2efa41e84 ]
The scnprintf() function silently truncates the printf() and returns
the number bytes that it was able to copy (not counting the NUL
terminator). Thus, the highest value it can return here is
"NAME_SIZE - 1" and the overflow check is dead code. Fix this by
using the snprintf() function which returns the number of bytes that
would have been copied if there was enough space and changing the
condition from "> NAME_SIZE" to ">= NAME_SIZE".
