The switch() logic there misses a break and a default case.
That makes it more prone to problems as the code change.

Add basic support for Maxim MAX96712 quad GMSL2 deserializers. The
driver is capable of powering on the device and configuring the MIPI
CSI-2 bus in a DPHY 4-lane configuration as well as operating the
internal VTG (Video Timing Generator) and VPG (Video Pattern Generator).
Using these features the driver is able to act as a 1080p @ 30 fps V4L2
video source. Producing either a checkerboard or gradient pattern on the
CSI-2 bus, selectable thru a V4L2 control.
While the driver is useful as-is and have been used to prove the correct
operation of the MAX96712 itself and "downstream" devices using the
MAX96712 as a video source there are a lot of features missing. Most
notably the ability to operate the GMSL bus.

While different sensors could have different colorspaces, the
colorspace V4L2 support didn't exist by the time atomisp driver
was written. So, the sensors won't have any data about that.

The current logic only initializes pipe->pix after setting up a
pipeline - e. g. after start streaming.
While it makes sense to get the format of the pipeline, when
it is set, this breaks support for generic applications, as they
rely on getting the current sensor format (which is usually the
highest resolution format).
So, implement a call to the sensor's get_fmt, when this is called
before setting up a pipeline.

Some `struct`s are `sizeof()`ed in sh_css_firmware.c file. So, I guess

## `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 3c0538fbad ("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 4f744a573d ("media: atomisp: make

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)`.

Some debug messages for error cases (messages contain "error: ") use
IA_CSS_DEBUG_TRACE_PRIVATE debug level. This causes these error messages
not to appear unless users raise debug output level to 7 or higher (using
module parameter, dbg_level=7).
So, use IA_CSS_DEBUG_ERROR debug level (dbg_level=1) instead considering
that these are error messages. There is already a macro IA_CSS_ERROR()
for this use case. Let's use it. It automatically appends "error: " at
the beginning and a newline to a message. Therefore, we can remove them
from these messages.
While here, remove the unnecessary newline from one IA_CSS_ERROR()

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]".

Special thanks to Nathan Chancellor who fixed the Clang bug[1][2]. This
bugfix only appears in Clang 14.0.0, so older versions still contain
the bug and -Wimplicit-fallthrough won't be enabled for them, for now.
This concludes a long journey and now we are finally getting rid

A regression fix for the Open Firmware interrupt mapping code where a

- Interrupt chip drivers:
- Workaround a limitation in SiFive PLIC interrupt chip which silently

- PCI/MSI:
- Prevent a use after free when PCI/MSI interrupts are released by
destroying the sysfs entries before freeing the memory which is

- Implement a mask quirk for the Nvidia ION AHCI chip which does not
advertise masking capability despite implementing it. Even worse the
chip comes out of reset with all MSI entries masked, which due to the
missing masking capability never get unmasked.
- Move the check which prevents accessing the MSI[X] masking for XEN
back into the low level accessors. The recent consolidation missed
that these accessors can be invoked from places which do not have
that check which broke XEN. Move them back to he original place
instead of sprinkling tons of these checks all over the code.
