The of_device_unregister call in therm_windtunnel's module_exit procedure
does not fully reverse the effects of of_platform_device_create in the
module_init prodedure. Once you unload this module, it is impossible
to load it ever again since only the first of_platform_device_create
call on the fan node succeeds.
This driver predates first git commit, and it turns out back then
of_platform_device_create worked differently than it does today.
So this is actually an old regression.
The appropriate function to undo of_platform_device_create now appears
to be of_platform_device_destroy, and switching to use this makes it
possible to unload and load the module as expected.

[ Upstream commit 14196e47c5ffe32af7ed5a51c9e421c5ea5bccce ]
In the xmon disassembly code there are several CPU feature checks to
determine what dialects should be passed to the disassembler. The
dialect controls which instructions the disassembler will recognise.
Unfortunately the checks are incorrect, because instead of passing a
single CPU feature they are passing a mask of feature bits.
For example the code:
if (cpu_has_feature(CPU_FTRS_POWER5))
dialect |= PPC_OPCODE_POWER5;
Is trying to check if the system is running on a Power5 CPU. But
CPU_FTRS_POWER5 is a mask of *all* the feature bits that are enabled on
a Power5.
In practice the test will always return true for any 64-bit CPU, because
at least one bit in the mask will be present in the CPU_FTRS_ALWAYS
mask.
Similarly for all the other checks against CPU_FTRS_xx masks.
Rather than trying to match the disassembly behaviour exactly to the
current CPU, just differentiate between 32-bit and 64-bit, and Altivec,
VSX and HTM.
That will cause some instructions to be shown in disassembly even
on a CPU that doesn't support them, but that's OK, objdump -d output
has the same behaviour, and if anything it's less confusing than some
instructions not being disassembled.

[ Upstream commit c2a57ee0f2f1ad8c970ff58b78a43e85abbdeb7f ]
When PERST# assert and deassert happens on the PERST# supported platforms,
both iATU0 and iATU6 will map inbound window to BAR0. DMA will access the
area that was previously allocated (iATU0) for BAR0, instead of the new
area (iATU6) for BAR0.
Right now, this isn't an issue because both iATU0 and iATU6 should
translate inbound accesses to BAR0 to the same allocated memory area.
However, having two separate inbound mappings for the same BAR is a
disaster waiting to happen.
The mappings between PCI BAR and iATU inbound window are maintained in the
dw_pcie_ep::bar_to_atu[] array. While allocating a new inbound iATU map for
a BAR, dw_pcie_ep_inbound_atu() API checks for the availability of the
existing mapping in the array and if it is not found (i.e., value in the
array indexed by the BAR is found to be 0), it allocates a new map value
using find_first_zero_bit().
The issue is the existing logic failed to consider the fact that the map
value '0' is a valid value for BAR0, so find_first_zero_bit() will return
'0' as the map value for BAR0 (note that it returns the first zero bit
position).
Due to this, when PERST# assert + deassert happens on the PERST# supported
platforms, the inbound window allocation restarts from BAR0 and the
existing logic to find the BAR mapping will return '6' for BAR0 instead of
'0' due to the fact that it considers '0' as an invalid map value.
Fix this issue by always incrementing the map value before assigning to
bar_to_atu[] array and then decrementing it while fetching. This will make
sure that the map value '0' always represents the invalid mapping."

[ Upstream commit 01a0a6cc8cfd9952e72677d48d56cf6bc4e3a561 ]
There's two problems with shared RCGs.
The first problem is that they incorrectly report the parent after
commit 703db1f5da ("clk: qcom: rcg2: Cache CFG register updates for
parked RCGs"). That's because the cached CFG register value needs to be
populated when the clk is registered. clk_rcg2_shared_enable() writes
the cached CFG register value 'parked_cfg'. This value is initially zero
due to static initializers. If a driver calls clk_enable() before
setting a rate or parent, it will set the parent to '0' which is
(almost?) always XO, and may not reflect the parent at registration. In
the worst case, this switches the RCG from sourcing a fast PLL to the
slow crystal speed.
The second problem is that the force enable bit isn't cleared. The force
enable bit is only used during parking and unparking of shared RCGs.
Otherwise it shouldn't be set because it keeps the RCG enabled even when
all the branches on the output of the RCG are disabled (the hardware has
a feedback mechanism so that any child branches keep the RCG enabled
when the branch enable bit is set). This problem wastes power if the clk
is unused, and is harmful in the case that the clk framework disables
the parent of the force enabled RCG. In the latter case, the GDSC the
shared RCG is associated with will get wedged if the RCG's source clk is
disabled and the GDSC tries to enable the RCG to do "housekeeping" while
powering on.
Both of these problems combined with incorrect runtime PM usage in the
display driver lead to a black screen on Qualcomm sc7180 Trogdor
chromebooks. What happens is that the bootloader leaves the
'disp_cc_mdss_rot_clk' enabled and the 'disp_cc_mdss_rot_clk_src' force
enabled and parented to 'disp_cc_pll0'. The mdss driver probes and
runtime suspends, disabling the mdss_gdsc which uses the
'disp_cc_mdss_rot_clk_src' for "housekeeping". The
'disp_cc_mdss_rot_clk' is disabled during late init because the clk is
unused, but the parent 'disp_cc_mdss_rot_clk_src' is still force enabled
because the force enable bit was never cleared. Then 'disp_cc_pll0' is
disabled because it is also unused. That's because the clk framework
believes the parent of the RCG is XO when it isn't. A child device of
the mdss device (e.g. DSI) runtime resumes mdss which powers on the
mdss_gdsc. This wedges the GDSC because 'disp_cc_mdss_rot_clk_src' is
parented to 'disp_cc_pll0' and that PLL is off. With the GDSC wedged,
mdss_runtime_resume() tries to enable 'disp_cc_mdss_mdp_clk' but it
can't because the GDSC has wedged all the clks associated with the GDSC
causing clks to stay stuck off.
This leads to the following warning seen at boot and a black screen
because the display driver fails to probe.

When there are rng sources registering at the hwrng core via
hwrng_register() a struct hwrng is delivered. There is a quality
field in there which is used to decide which of the registered
hw rng sources will be used by the hwrng core.
With commit 16bdbae394 ("hwrng: core - treat default_quality as
a maximum and default to 1024") there came in a new default of
1024 in case this field is empty and all the known hw rng sources
at that time had been reworked to not fill this field and thus
use the default of 1024.
The code choosing the 'better' hw rng source during registration
of a new hw rng source has never been adapted to this and thus
used 0 if the hw rng implementation does not fill the quality field.
So when two rng sources register, one with 0 (meaning 1024) and
the other one with 999, the 999 hw rng will be chosen.
As the later invoked function hwrng_init() anyway adjusts the
quality field of the hw rng source, this adjustment is now done
during registration of this new hw rng source.
Tested on s390 with two hardware rng sources: crypto cards and
trng true random generator device driver.

[ Upstream commit 0c5275bf75ec3708d95654195ae4ed80d946d088 ]
When creating a QP, one of the attributes is TS format (timestamp).
In some devices, we have a limitation that all QPs should have the same
ts_format. The ts_format is chosen based on the device's capability.
The qp_ts_format cap resides under the RoCE caps table, and the
cap will be 0 when RoCE is disabled. So when RoCE is disabled, the
value that should be queried is sq_ts_format under HCA caps.
Consider the case when the system supports REAL_TIME_TS format (0x2),
some QPs are created with REAL_TIME_TS as ts_format, and afterwards
RoCE gets disabled. When trying to construct a new QP, we can't use
the qp_ts_format, that is queried from the RoCE caps table, Since it
leads to passing 0x0 (FREE_RUNNING_TS) as the value of the qp_ts_format,
which is different than the ts_format of the previously allocated
QPs REAL_TIME_TS format (0x2).
Thus, to resolve this, read the sq_ts_format, which also reflect
the supported ts format for the QP when RoCE is disabled.

[ Upstream commit e69386d4a42afa5da6bfdcd4ac5ec61e1db04c61 ]
The GPU clocks/GDSCs have been marked critical from the clock driver
but the GPU driver votes on these resources as per the HW requirement.
In the case where these clocks & GDSCs are left enabled, would have
power impact and also cause GPU stability/corruptions.
Fix the same by removing the CLK_IS_CRITICAL for clocks and ALWAYS_ON
flags for the GPU GDSCs.

IRQ lookup functions such as those in ACPI can return error values when
an IRQ is not defined. The i2c core driver converts the error codes to a
value of 0 and the SPI bus driver passes them unaltered to client device
drivers.
The cs35l56 driver should only accept positive non-zero values as IRQ
numbers.
