The framebuffer configuration for edo pdx203, written in edo dtsi (which
is overwritten in pdx206 dts for its smaller panel) has to use a

has been initialized to. Downstream userspace also has access to (and

Driver is not handling the wraparound of the mbox producer index correctly.
Currently the wraparound happens once u32 max is reached.
Bit 31 of the producer index register is special and should be set
only once for the first command. Because the producer index overflow
setting bit31 after a long time, FW goes to initialization sequence
and this causes FW hang.
Fix is to wraparound the mbox producer index once it reaches u16 max.

gpu->revn is not yet set (it is set later, in adreno_gpu_init()) and
thus the condition is always false. Check config->rev instead.

Device tree node names should be generic. The planned device node name
for the GPU, according to the bindings and posted DT changes, is "gpu",
not "mali".
Fix the GPU node name in the SVS driver to follow.
The Device Tree was using invalid node names for the ACT8600 regulators.
To be fair, it is not the original committer's fault, as the
documentation did gives invalid names as well.
In theory, the fix should have been to modify the driver to accept the
alternative names. However, even though the act8865 driver spits
warnings, the kernel seemed to work fine with what is currently
supported upstream. For that reason, I think it is okay to just update
the DTS.
I removed the "regulator-name" too, since they really didn't bring any
information. The node names are enough.

The PMON_CONFIG register on ADM1272 is a 16 bit register. Writing a 8 bit

unexpected side effects. Fix by writing the 16 bit register value.
Also, it has been reported that temperature readings are sometimes widely

function, and clarify in the error message that an attempt was made to
enable both VOUT and temperature monitoring.
Last but not least, return the error code reported by the underlying I2C
controller and not -ENODEV if updating the PMON_CONFIG register fails.

The hfi1 user SDMA pinned-page cache will leave a stale cache entry when
the cache-entry's virtual address range is invalidated but that cache
entry is in-use by an outstanding SDMA request.
Subsequent user SDMA requests with buffers in or spanning the virtual
address range of the stale cache entry will result in packets constructed
from the wrong memory, the physical pages pointed to by the stale cache
entry.
To fix this, remove mmu_rb_node cache entries from the mmu_rb_handler
cache independent of the cache entry's refcount. Add 'struct kref
refcount' to struct mmu_rb_node and manage mmu_rb_node lifetime with
kref_get() and kref_put().
mmu_rb_node.refcount makes sdma_mmu_node.refcount redundant. Remove

code to use mmu_rb_node.refcount.
Move the mmu_rb_handler destructor call after a

mmu_rb_handler's workqueue to queue themselves up for destruction from an
interrupt context may do so.

On Meson8 uart_B and uart_C do not work, because they are relying on
incorrect clocks. Change the references of pclk to the correct CLKID
(UART1 for uart_B and UART2 for uart_C), to allow use of the two uarts.
This was originally reported by Hans-Frieder Vogt for Meson8b [0], but
the same bug is also present in meson8.dtsi
When using the codec through the generic audio graph card, there are at
least two calls of es8316_set_dai_sysclk(), with the effect of limiting
the allowed sample rates according to the MCLK/LRCK ratios supported by
the codec:
1. During audio card setup, to set the initial MCLK - see
asoc_simple_init_dai().
2. Before opening a stream, to update MCLK, according to the stream
sample rate and the multiplication factor - see
asoc_simple_hw_params().
In some cases the initial MCLK might be set to a frequency that doesn't
match any of the supported ratios, e.g. 12287999 instead of 12288000,
which is only 1 Hz below the supported clock, as that is what the
hardware reports. This creates an empty list of rate constraints, which
is further passed to snd_pcm_hw_constraint_list() via
es8316_pcm_startup(), and causes the following error on the very first
access of the sound card:
$ speaker-test -D hw:Analog,0 -F S16_LE -c 2 -t wav
Broken configuration for playback: no configurations available: Invalid argument
Setting of hwparams failed: Invalid argument
Note that all subsequent retries succeed thanks to the updated MCLK set
at point 2 above, which uses a computed frequency value instead of a
reading from the hardware registers. Normally this would have mitigated
the issue, but es8316_pcm_startup() executes before the 2nd call to
es8316_set_dai_sysclk(), hence it cannot make use of the updated
constraints.
Since es8316_pcm_hw_params() performs anyway a final validation of MCLK
against the stream sample rate and the supported MCLK/LRCK ratios, fix
the issue by ensuring that sysclk_constraints list is only set when at
least one supported sample rate is autodetected by the codec.
According to ES8316 datasheet, the register at address 0x2B, which is
related to the above mixer control, contains by default the value 0xB0.
Considering the corresponding ALC target bits (ALCLVL) are 7:4, the
control is initialized with 11, which is one step above the maximum
value allowed by the driver:
The tests performed using the VU meter feature (--vumeter=TYPE) of
arecord/aplay confirm the specs are correct and there is no measured
gain if the 1011-1111 range would have been mapped to 0 dB:
dB gain | VU meter %
--------+-----------
-6.0 | 30-31
-4.5 | 35-36
-3.0 | 42-43
-1.5 | 50-51
0.0 | 50-51
Increment the max value allowed for ALC Capture Target Volume control,
so that it matches the hardware default. Additionally, update the
related TLV to prevent an artificial extension of the dB gain range.
Add the qcom,controlled-remotely property for the blsp2_bam
controller node. This board requires this, otherwise the board stalls
during the boot for some reason (most probably because TZ mishandles the
protection error and keeps on looping somewhere inside).

The datasheet describes the following initialization flow including
minimum delay times between each step:
1. DSI data lanes need to be in LP-11 and the clock lane in HS mode
2. toggle EN signal
3. initialize registers
4. enable PLL
5. soft reset
6. enable DSI stream
7. check error status register
To meet this requirement we need to make sure the host bridge's
pre_enable() is called first by using the pre_enable_prev_first
flag.
Furthermore we need to split enable() into pre_enable() which covers
steps 2-5 from above and enable() which covers step 7 and is called
after the host bridge's enable().

The 96Boards specification expects a 1.8V power rail on the low-speed
expansion connector that is able to provide at least 0.18W / 100 mA.
According to the DB410c hardware user manual this is done by connecting
both L15 and L16 in parallel with up to 55mA each (for 110 mA total) [1].
Unfortunately the current regulator setup in the DB410c device tree
does not implement the specification correctly and only provides 5 mA:
- Only L15 is marked always-on, so L16 is never enabled.
- Without specifying a load the regulator is put into LPM where
it can only provide 5 mA.
Fix this by:
- Adding proper voltage constraints for L16.
- Making L16 always-on.
- Adding regulator-system-load for both L15 and L16. 100 mA should be
available in total, so specify 50 mA for each. (The regulator
hardware can only be in normal (55 mA) or low-power mode (5 mA) so
this will actually result in the expected 110 mA total...)
For some reason DB410c has completely bogus regulator constraints that
actually just correspond to the programmable voltages which are already
provided by the regulator driver. Some of them are not just outside the
recommended operating conditions of the APQ8016E SoC but even exceed
the absolute maximum ratings, potentially risking permanent device
damage.
In practice it's not quite as dangerous thanks to the RPM firmware:
It turns out that it has its own voltage constraints and silently
clamps all regulator requests. For example, requesting 3.3V for L5
(allowed by the current regulator constraints!) still results in 1.8V
being programmed in the actual regulator hardware.
Experimentation with various voltages shows that the internal RPM
voltage constraints roughly correspond to the safe "specified range"
in the PM8916 Device Specification (rather than the "programmable
range" used inside apq8016-sbc.dtsi right now).
Combine those together with some fixed voltages used in the old
msm-3.10 device tree from Qualcomm to give DB410c some actually valid
voltage constraints.
Add a family compatible for QCE IP on SM8550 SoC, which is equal to QCE IP
found on SM8150 SoC and described in the recently updated device tree
bindings documentation, as well add a generic QCE IP family compatible.

On MSM8916 the wireless connectivity functionality (WiFi/Bluetooth) is
split into the digital part inside the SoC and the analog RF part inside
a supplementary WCN36xx chip. For MSM8916, three different options
exist:
Choosing one of these is up to the board vendor. This means that the
compatible belongs into the board-specific DT part so people porting
new boards pay attention to set the correct compatible.
Right now msm8916.dtsi sets "qcom,wcn3620" as default compatible,
which does not work at all for boards that have WCN3660B or WCN3680B.
Remove the default compatible from msm8196.dtsi and move it to the board
DT as follows:
- Boards with only &pronto { status = "okay"; } used the default
"qcom,wcn3620" so far. They now set this explicitly for &wcnss_iris.
- Boards with &pronto { ... iris { compatible = "qcom,wcn3660b"; }};
already had an override that just moves to &wcnss_iris now.
- For msm8916-samsung-a2015-common.dtsi the WCN compatible differs for
boards making use of it (a3u: wcn3620, a5u: wcn3660b, e2015: wcn3620)
so the definitions move to the board-specific DT part.
Since this requires touching all the board DTs, use this as a chance to
name the WCNSS-related labels consistently, so everything is grouped
properly when sorted alphabetically.
No functional change, just clean-up for more clarity & easier porting.
Aside from ordering the generated DTBs are identical.

Aaro reports problems on the OSK1 board after we altered
the dynamic base for GPIO allocations.
It appears this happens because the OMAP driver now
allocates GPIO numbers dynamically, so all that is
references by number is a bit up in the air.
Let's bite the bullet and try to just move the gpio_chip
in the tps65010 MFD driver over to using dynamic allocations.
Alter everything in the OSK1 board file to use a GPIO
descriptor table and lookups.
Utilize the NULL device to define some board-specific
GPIO lookups and use these to immediately look up the
same GPIOs, convert to IRQ numbers and pass as resources
to the devices. This is ugly but should work.
The .setup() callback for tps65010 was used for some GPIO
hogging, but since the OSK1 is the only user in the entire
kernel we can alter the signatures to something that
is helpful and make a clean transition.

During probe, the driver registers i2c dummy devices and populates the
aux bus, which registers a device for the panel. After doing that, the
driver can still defer probe if needed. This ordering of operations is
troublesome however, because the deferred probe work will retry probing
all pending devices every time a new device is registered. Therefore, if
modules need to be loaded in order to satisfy the dependencies for this
driver to complete probe, the kernel will stall, since it'll keep trying
to probe the anx7625 driver, but never succeed, given that modules would
only be loaded after the deferred probe work completes.
Two changes are required to avoid this issue:
* Move of_find_mipi_dsi_host_by_node(), which can defer probe, to before
anx7625_register_i2c_dummy_clients() and
devm_of_dp_aux_populate_ep_devices(), which register devices.
* Make use of the done_probing callback when populating the aux bus,
so that the bridge registration is only done after the panel is
probed. This is required because the panel might need to defer probe,
but the aux bus population needs the i2c dummy devices working, so
this call couldn't just be moved to an earlier point in probe.
One caveat is that if the panel is described outside the aux bus, the
probe loop issue can still happen, but we don't have a way to avoid
it in that case since there's no callback available.

too.
