[ Upstream commit f85534113f ]
The MT6380 regulator typically used together with MT7622 does not
support the current maximum processor and SRAM voltage in the cpufreq
driver (1360000uV).
For MT7622 limit processor and SRAM supply voltages to 1350000uV to
avoid having the tracking algorithm request unsupported voltages from
the regulator.
On MT7623 there is no separate SRAM supply and the maximum voltage used
is 1300000uV. Create dedicated platform data for MT7623 to cover that
case as well.

The fwnode_irq_get() and the fwnode_irq_get_byname() return 0 upon
device-tree IRQ mapping failure. This is contradicting the
fwnode_irq_get_byname() function documentation and can potentially be a
source of errors like:
int probe(...) {
...
irq = fwnode_irq_get_byname();
if (irq <= 0)
return irq;
...
}
Here we do correctly check the return value from fwnode_irq_get_byname()
but the driver probe will now return success. (There was already one
such user in-tree).
Change the fwnode_irq_get_byname() to work as documented and make also the
fwnode_irq_get() follow same common convention returning a negative errno
upon failure.

[ Upstream commit 285cff4c04 ]
The KVM_S390_GET_CMMA_BITS ioctl may return incorrect values when userspace
specifies a start_gfn outside of memslots.
This can occur when a VM has multiple memslots with a hole in between:
+-----+----------+--------+--------+
| ... | Slot N-1 | <hole> | Slot N |
+-----+----------+--------+--------+
^ ^ ^ ^
| | | |
GFN A A+B | |
A+B+C |
A+B+C+D
When userspace specifies a GFN in [A+B, A+B+C), it would expect to get the
CMMA values of the first dirty page in Slot N. However, userspace may get a
start_gfn of A+B+C+D with a count of 0, hence completely skipping over any
dirty pages in slot N.
The error is in kvm_s390_next_dirty_cmma(), which assumes
gfn_to_memslot_approx() will return the memslot _below_ the specified GFN
when the specified GFN lies outside a memslot. In reality it may return
either the memslot below or above the specified GFN.
When a memslot above the specified GFN is returned this happens:
- ofs is calculated, but since the memslot's base_gfn is larger than the
specified cur_gfn, ofs will underflow to a huge number.
- ofs is passed to find_next_bit(). Since ofs will exceed the memslot's
number of pages, the number of pages in the memslot is returned,
completely skipping over all bits in the memslot userspace would be
interested in.
Fix this by resetting ofs to zero when a memslot _above_ cur_gfn is
returned (cur_gfn < ms->base_gfn).

[ Upstream commit 7d45a43225 ]
Stop using half pixelclock for binned modes this fixes:
1. The exposure being twice as high for binned mods (due to the half clk)
2. The framerate being 15 fps instead of 30 fps
The original code with fixed per mode register lists did use half pixel
clk, but this should be combined with using half for the VTS value too.
Using half VTS fixes the framerate issue, but this has the undesired
side-effect of change the exposure ctrl range (half the range, double
the amount of exposure per step).

[ Upstream commit 1657f2934d ]
Ideally, strlen(cur->string.pointer) and strlen(out) would be the same.
But this code is using strscpy() to avoid a potential buffer overflow.
So in the same way we should take the strlen() of the smaller string to
avoid a buffer overflow in the caller, gmin_get_var_int().

[ Upstream commit 927e78ac8b ]
ALIGN() expects its second argument to be a power of 2, otherwise
incorrect results are produced for some inputs. The output can be
both larger or smaller than what is expected.
For example, ALIGN(304, 192) equals 320 instead of 384, and
ALIGN(65, 192) equals 256 instead of 192.
However, nestling two ALIGN() as is done in this case seem to only
produce results equal to or bigger than the expected result if ALIGN()
had handled non powers of two, and that in turn results in framesizes
that are either the correct size or too large.
Fortunately, since 192 * 4 / 3 equals 256, it turns out that one ALIGN()
is sufficient.

[ Upstream commit c45b2835e7 ]
child_fwnode should be a read only property based on the DT or ACPI. If
it's cleared on the parent device when a child is unloaded, then when
the child is loaded again the connection won't be remade.
child_dev should be cleared instead which signifies that the connection
should be remade when the child_fwnode registers a new coresight_device.
Similarly the reference count shouldn't be decremented as long as the
parent device exists. The correct place to drop the reference is in
coresight_release_platform_data() which is already done.
Reproducible on Juno with the following steps:
# load all coresight modules.
$ cd /sys/bus/coresight/devices/
$ echo 1 > tmc_etr0/enable_sink
$ echo 1 > etm0/enable_source
# Works fine ^

by each console write (serial8250_console_write()) under the port

Since the port lock is already being taken for the stop_rx() callback
and since it is safe to call cancel_delayed_work() while holding the
