The driver wrongly assummed that tx_submit() will start the transfer,
which is not the case, now that the at_xdmac driver is fixed. tx_submit
is supposed to push the current transaction descriptor to a pending queue,
waiting for issue_pending to be called. issue_pending must start the
transfer, not tx_submit.

The tx_submit() method of struct dma_async_tx_descriptor is entitled
to do sanity checks and return errors if encountered. It's not the
case for the DMA controller drivers that this client is using
(at_h/xdmac), because they currently don't do sanity checks and always
return a positive cookie at tx_submit() method. In case the controller
drivers will implement sanity checks and return errors, print a message
so that the client will be informed that something went wrong at
tx_submit() level.

CE interrupt configuration uses host ce parameters to assign/free

If the remote function did not ACK the reception of a message, the
function __adf_iov_putmsg() could detect it as a collision.
This was due to the fact that the collision and the timeout checks after
the ACK loop were in the wrong order. The timeout must be checked at the
end of the loop, so fix by swapping the order of the two checks.

[ Upstream commit 93d9e6f93e1586fcc97498c764be2e8c8401f4bd ]
The thermal pressure signal gives information to the scheduler about
reduced CPU capacity due to thermal. It is based on a value stored in
a per-cpu 'thermal_pressure' variable. The online CPUs will get the
new value there, while the offline won't. Unfortunately, when the CPU
is back online, the value read from per-cpu variable might be wrong
(stale data). This might affect the scheduler decisions, since it
sees the CPU capacity differently than what is actually available.
Fix it by making sure that all online+offline CPUs would get the
proper value in their per-cpu variable when there is throttling
or throttling is removed.

As it turns out, apparently some machines will actually leave additional
backlight functionality like dynamic backlight control on before the OS
loads. Currently we don't take care to disable unsupported features when
writing back the backlight mode, which can lead to some rather strange
looking behavior when adjusting the backlight.
So, let's fix this by just not reading back the current backlight mode on
initial enable. I don't think there should really be any downsides to this,
and this will ensure we don't leave any unsupported functionality enabled.
This should fix at least one (but not all) of the issues seen with DPCD
backlight support on fi-bdw-samus

The ath11k driver is caching the information about RSN/WPA IE in the
configured beacon template. The cached information is used during
associations to figure out whether 4-way PKT/2-way GTK peer flags need to
be set or not.
But the code never cleared the state when no such IE was found. This can
for example happen when moving from an WPA/RSN to an open setup. The
(seemingly connected) peer was then not able to communicate over the
link because the firmware assumed a different (encryption enabled) state
for the peer.

[ Upstream commit 086c921a354089f209318501038d43c98d3f409f ]
Some ETSI countries have a small overlap in the wireless-regdb with an ETSI
channel (5590-5650). A good example is Australia:
country AU: DFS-ETSI
(2400 - 2483.5 @ 40), (36)
(5150 - 5250 @ 80), (23), NO-OUTDOOR, AUTO-BW
(5250 - 5350 @ 80), (20), NO-OUTDOOR, AUTO-BW, DFS
(5470 - 5600 @ 80), (27), DFS
(5650 - 5730 @ 80), (27), DFS
(5730 - 5850 @ 80), (36)
(57000 - 66000 @ 2160), (43), NO-OUTDOOR
If the firmware (or the BDF) is shipped with these rules then there is only
a 10 MHz overlap with the weather radar:
* below: 5470 - 5590
* weather radar: 5590 - 5600
* above: (none for the rule "5470 - 5600 @ 80")
There are several wrong assumption in the ath11k code:
* there is always a valid range below the weather radar
(actually: there could be no range below the weather radar range OR range
could be smaller than 20 MHz)
* intersected range in the weather radar range is valid
(actually: the range could be smaller than 20 MHz)
* range above weather radar is either empty or valid
(actually: the range could be smaller than 20 MHz)
These wrong assumption will lead in this example to a rule
(5590 - 5600 @ 20), (N/A, 27), (600000 ms), DFS, AUTO-BW
which is invalid according to is_valid_reg_rule() because the freq_diff is
only 10 MHz but the max_bandwidth is set to 20 MHz. Which results in a
rejection like:

ath11k c000000.wifi: failed to perform regd update : -22
Invalid regulatory domain detected
To avoid this, the algorithm has to be changed slightly. Instead of
splitting a rule which overlaps with the weather radar range into 3 pieces
and accepting the first two parts blindly, it must actually be checked for
each piece whether it is a valid range. And only if it is valid, add it to
the output array.
When these checks are in place, the processed rules for AU would end up as
country AU: DFS-ETSI
(2400 - 2483 @ 40), (N/A, 36), (N/A)
(5150 - 5250 @ 80), (6, 23), (N/A), NO-OUTDOOR, AUTO-BW

(5650 - 5730 @ 80), (6, 27), (0 ms), DFS, AUTO-BW
(5730 - 5850 @ 80), (6, 36), (N/A), AUTO-BW
and will be accepted by the wireless regulatory code.

## `if (pipe->stream->config.mode == IA_CSS_INPUT_MODE_TPG) {` case
The intel-aero atomisp has `#if defined(IS_ISP_2400_SYSTEM)` [1]. It is
to be defined in the following two places [2]:
- css/hive_isp_css_common/system_global.h
- css/css_2401_csi2p_system/system_global.h
and the former file is to be included on ISP2400 devices, too. So, it
is to be defined for both ISP2400 and ISP2401 devices.
Because the upstreamed atomisp driver now supports only ISP2400 and
ISP2401, just remove the ISP version test again. This matches the other
upstream commits like 3c0538fbad9f ("media: atomisp: get rid of most
checks for ISP2401 version").
While here, moved the comment for define GP_ISEL_TPG_MODE to the
appropriate place.

## `isys_stream_descr->polling_mode` case
This does not exist on the intel-aero atomisp. This is because it is
based on css version irci_stable_candrpv_0415_20150521_0458.
On the other hand, the upstreamed atomisp is based on the following css
version depending on the ISP version using ifdefs:
- ISP2400: irci_stable_candrpv_0415_20150521_0458
- ISP2401: irci_master_20150911_0724
The `isys_stream_descr->polling_mode` usage was added on updating css
version to irci_master_20150701_0213 [3].
So, it is not a ISP version specific thing, but css version specific
thing. Because the upstreamed atomisp driver uses irci_master_20150911_0724
for ISP2401, re-add the ISP version check for now.
I say "for now" because ISP2401 should eventually use the same css
version with ISP2400 (i.e., irci_stable_candrpv_0415_20150521_0458)

it was added on commit 4f744a573db3 ("media: atomisp: make
sh_css_sp_init_pipeline() ISP version independent") for ISP2401. Because
the upstreamed atomisp for the ISP2401 part is based on
irci_master_20150911_0724, hence the difference.
Because the upstreamed atomisp driver uses irci_master_20150911_0724
for ISP2401, revert the test back to `if (IS_ISP2401)`.

When comparing with intel-aero atomisp [1], it looks like
punit_ddr_dvfs_enable() should take `false` as an argument on mrfld_power
up case.
Code from the intel-aero kernel [1]:
int atomisp_mrfld_power_down(struct atomisp_device *isp)
{
[...]
/*WA:Enable DVFS*/
if (IS_CHT)
punit_ddr_dvfs_enable(true);
int atomisp_mrfld_power_up(struct atomisp_device *isp)
{
[...]
/*WA for PUNIT, if DVFS enabled, ISP timeout observed*/
if (IS_CHT)
punit_ddr_dvfs_enable(false);
This patch fixes the inverted argument as per the intel-aero code, as
well as its comment. While here, fix space issues for comments in
atomisp_mrfld_power().
Note that it does not seem to be possible to unify the up/down cases for
punit_ddr_dvfs_enable(), i.e., we can't do something like the following:
if (IS_CHT)
punit_ddr_dvfs_enable(!enable);
because according to the intel-aero code [1], the DVFS is disabled
before "writing 0x0 to ISPSSPM0 bit[1:0]" and the DVFS is enabled after
"writing 0x3 to ISPSSPM0 bit[1:0]".
