[ Upstream commit 4a90bbb478dbf18ecdec9dcf8eb708e319d24264 ]
The current driver uses a value from register TEST_O as the original
value for register TEST_I, though, the value is overwritten by "param",
so there is a bug that the original value isn't no longer used.
The value of TEST_O[7:0] should be masked with "mask", replaced with
"param", and placed in the bitfield TESTI_DAT_MASK as new TEST_I value.

In sdw_prep_deprep_slave_ports(), after the wait_for_completion()
the DP prepare status register is read. If this indicates that the
port is now prepared, the code should continue with the port setup.
It is irrelevant whether the wait_for_completion() timed out if the
port is now ready.
The previous implementation would always fail if the
wait_for_completion() timed out, even if the port was reporting
successful prepare.
This patch also fixes a minor bug where the return from sdw_read()
was not checked for error - any error code with LSBits clear could
be misinterpreted as a successful port prepare.

Variable "size" has type "phys_addr_t", which can be either 32-bit or
64-bit on 32-bit systems, while "unsigned long" is always 32-bit on
32-bit systems. Hence the cast in
(unsigned long)size / SZ_1M
may truncate a 64-bit size to 32-bit, as casts have a higher operator
precedence than divisions.
Fix this by inverting the order of the cast and division, which should
be safe for memory blocks smaller than 4 PiB. Note that the division is
actually a shift, as SZ_1M is a power-of-two constant, hence there is no
need to use div_u64().
While at it, use "%lu" to format "unsigned long".

Support for magic baud rate divisors of 32770 and 32769 used with SMSC
Super I/O chips for extra baud rates of 230400 and 460800 respectively
where base rate is 115200[1] has been added around Linux 2.5.64, which
predates our repo history, but the origin could be identified as commit
2a717aad772f ("Merge with Linux 2.5.64.") with the old MIPS/Linux repo
also at: <git://git.kernel.org/pub/scm/linux/kernel/git/ralf/linux.git>.
Code that is now in `serial8250_do_get_divisor' was added back then to
`serial8250_get_divisor', but that code would only ever trigger if one
of the higher baud rates was actually requested, and that cannot ever
happen, because the earlier call to `serial8250_get_baud_rate' never
returns them. This is because it calls `uart_get_baud_rate' with the
maximum requested being the base rate, that is clk/16 or 115200 for SMSC
chips at their nominal clock rate.
Fix it then and allow UPF_MAGIC_MULTIPLIER baud rates to be selected, by
requesting the maximum baud rate of clk/4 rather than clk/16 if the flag
has been set. Also correct the minimum baud rate, observing that these
ports only support actual (non-magic) divisors of up to 32767 only.

Driver code call 'devm_of_pci_get_host_bridge_resources'
to get resources and properly fill 'bridge->windows' and
'bridge->dma_ranges'. After parsing the ranges and store
as resources, at the end it makes a call to pci function
'pci_add_resource_offset' to set the offset for the
memory resource. To calculate offset, resource start address
subtracts pci address of the range. MT7621 does not need
any offset for the memory resource. Moreover, setting an
offset got into 'WARN_ON' calls from pci devices driver code.
Until now memory range pci_addr was being '0x00000000' and
res->start is '0x60000000' but becase pci controller driver
was manually setting resources and adding them using pci function
'pci_add_resource' where a zero is passed as offset, things
was properly working. Since PCI_IOBASE is defined now for
ralink we don't set nothing manually anymore so we have to
properly fix PCI address for this range to make things work
and the new pci address must be set to '0x60000000'. Doing
in this way the subtract result obtain zero as offset
and pci device driver code properly works.

There is a leak in rtl8712 driver.
The problem was in non-freed adapter data if
firmware load failed.
This leak can be reproduced with this code:
https://syzkaller.appspot.com/text?tag=ReproC&x=16612f02d00000,
Autoload must fail (to not hit memory leak reported by syzkaller)
There are 2 possible ways how rtl871x_load_fw_cb() and
r871xu_dev_remove() can be called (in case of fw load error).
1st case:
r871xu_dev_remove() then rtl871x_load_fw_cb()
In this case r871xu_dev_remove() will wait for
completion and then will jump to the end, because
rtl871x_load_fw_cb() set intfdata to NULL:
if (pnetdev) {
struct _adapter *padapter = netdev_priv(pnetdev);
/* never exit with a firmware callback pending */
wait_for_completion(&padapter->rtl8712_fw_ready);
pnetdev = usb_get_intfdata(pusb_intf);
usb_set_intfdata(pusb_intf, NULL);
if (!pnetdev)
goto firmware_load_fail;
... clean up code here ...
}
2nd case:
rtl871x_load_fw_cb() then r871xu_dev_remove()
In this case pnetdev (from code snippet above) will
be zero (because rtl871x_load_fw_cb() set it to NULL)
And clean up code won't be executed again.
So, in all cases we need to free adapted data in rtl871x_load_fw_cb(),
because disconnect function cannot take care of it. And there won't be
any race conditions, because complete() call happens after setting
intfdata to NULL.
In previous patch I moved out free_netdev() from r8712_free_drv_sw()
and that's why now it's possible to free adapter data and then call
complete.

Every time the hub signals a reset while we (device) are hsotg->connected,
dwc2_hsotg_core_init_disconnected() is called, which in turn calls
dwc2_hs_phy_init().
GUSBCFG.USBTrdTim is cleared upon Core Soft Reset, so if
hsotg->params.phy_utmi_width is 8-bit, the value of GUSBCFG.USBTrdTim (the
default one: 0x5, corresponding to 16-bit) is always different from
hsotg->params.phy_utmi_width, thus dwc2_core_reset() is called every
time (usbcfg != usbcfg_old), which causes 2 issues:
1) The call to dwc2_core_reset() does another reset 300us after the initial
Chirp K of the first reset (which should last at least Tuch = 1ms), and
messes up the High-speed Detection Handshake: both hub and device drive
current into the D+ and D- lines at the same time.
2) GUSBCFG.USBTrdTim is cleared by the second reset, so its value is always
the default one (0x5).
Setting GUSBCFG.USBTrdTim after the potential call to dwc2_core_reset()
fixes both issues. It is now set even when select_phy is false because the
cost of the Core Soft Reset is removed.

In commit b02002cc4c ("s390/pci: Implement ioremap_wc/prot() with
MIO") we implemented both ioremap_wc() and ioremap_prot() however until
now we had not set HAVE_IOREMAP_PROT in Kconfig, do so now.
This also requires implementing pte_pgprot() as this is used in the
generic_access_phys() code enabled by CONFIG_HAVE_IOREMAP_PROT. As with
ioremap_wc() we need to take the MMIO Write Back bit index into account.
Moreover since the pgprot value returned from pte_pgprot() is to be used
for mappings into kernel address space we must make sure that it uses
appropriate kernel page table protection bits. In particular a pgprot
value originally coming from userspace could have the _PAGE_PROTECT
bit set to enable fault based dirty bit accounting which would then make
the mapping inaccessible when used in kernel address space.

features on a separate line:
pci 0000:00:00.2: AMD-Vi: Extended features (0x206d73ef22254ade):
PPR X2APIC NX GT IA GA PC GA_vAPIC
The second line is emitted via 'pr_cont', which causes it to have a
different ('warn') loglevel compared to the previous line ('info').
Commit 9a295ff0ff attempted to rectify this by removing the newline
from the pci_info format string, but this doesn't work, as pci_info
calls implicitly append a newline anyway.
Printing the decoded features on the same line would make it quite long.
Instead, change pci_info() to pr_info() to omit PCI bus location info,
which is also shown in the preceding message. This results in:
