[hverkuil: drop docbook tags, not needed]
When Gen3 support was first added to this R-Car VIN and CSI-2 driver the
routing was centred around the CHSEL register which multiplexes the
different parallel buses that sit between the CSI-2 receivers source
side and the VIN dma engines. This was a bad design as the multiplexing
do allow for only a few combinations and do not play nice with many
video streams in the system.
For example it's only possible for CSI-2 Virtual Channels 0 and 1 of any
given CSI-2 receiver to be used together with the scaler.
Later datasheets have expanded the documentation and it is now possible
to improve on this design by allowing any Virtual Channel to be routed
to any R-Car VIN instance, provided that there exists a parallel bus
between them. This increases the flexibility as all Virtual Channels can
now be used together with the scaler for example.
The redesign is not however perfect. While the new design allows for
many more routes, two constrains limit a small portion of routes that
was possible in the old design but are no more.
- It is no longer possible to route the same CSI-2 and VC to more then
one VIN at a time. This was theoretically possible before if the
specific SoC allowed for the same CSI-2 and VC to be routed to two
different VIN capture groups.
- It is no longer possible to simultaneously mix links from two CSI-2 IP
blocks to the same VIN capture group.
For example if VIN2 is capturing from CSI40 then VIN{0,1,3} must also
capture from CSI40. While VIN{4,5,6,7} is still free to capture from
any other CSI-2 IP in the system. Once all VIN{0,1,2,3} links to CSI40
are disabled that VIN capture group is free again to capture from any
other CSI-2 IP it is connected to.
At the core of the redesign is greater cooperator of the R-Car VIN and
CSI-2 drivers in configuring the routing. The VIN driver is after this
change only responsible to configure the full VIN capture groups
parallel buses to be to a particular CSI-2 IP. While the configuration
of which CSI-2 Virtual Channel is outputted on which of the R-Car CSI-2
IP output ports is handled by the CSI-2 driver.
Before this change the CSI-2 Virtual Channel to output port was static
in the CSI-2 driver and the different links only manipulated the VIN
capture groups CHSEL register. With this change both the CHSEl register
and the CSI-2 routing VCDT registers are modified for greater
flexibility.
This change touches both the R-Car VIN and R-Car CSI-2 drivers in the
same commit as both drivers cooperate closely and one change without the
other would more or less break video capture.

VSP hardware could be used (e.g. by the bootloader) before driver load,
and some interrupts could be left in enabled and pending state. In this
case, setting up VSP interrupt handler without masking interrupts before
causes interrupt handler to be immediately called (and crash due to null
vsp->info dereference).
Fix that by explicitly masking all interrupts before setting the interrupt
handler. To do so, have to set the interrupt handler later, after hw
revision is already detected and number of interrupts to mask gets
known.

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields. Wrap the target region
in struct_group(). This additionally fixes a theoretical misalignment
of the copy (since the size of "buf" changes between 64-bit and 32-bit,
but this is likely never built for 64-bit).
FWIW, I think this code is totally broken on 64-bit (which appears to
not be a "real" build configuration): it would either always fail (with
an uninitialized data->buf_size) or would cause corruption in userspace
due to the copy_to_user() in the call path against an uninitialized
data->buf value:
omap3isp_stat_request_statistics_time32(...)
struct omap3isp_stat_data data64;
...
omap3isp_stat_request_statistics(stat, &data64);
int omap3isp_stat_request_statistics(struct ispstat *stat,

if (buf->buf_size > data->buf_size) {
...
return ERR_PTR(-EINVAL);
}
...
rval = copy_to_user(data->buf,

Regardless, additionally initialize data64 to be zero-filled to avoid

Previous reg-field, 0x98[11:0], stands for the period of the detected
hsync signal.
Use the correct reg, 0xa0, to get h-total in pixels.

In ast2500, engine will stop occasionally for 1360x768.
This is a bug which has been addressed, but the workaround is specific
for 1680 only. Here we make it more complete.

To prepare for usage of the v4l2_fwnode_bus_* data structures to
describe bus configuration in the subdev .get_mbus_config() operation,
rename the structures with a v4l2_mbus_config_ prefix instead of
v4l2_fwnode_bus_, and move them to v4l2_mediabus.h.

The subdev .set_mbus_config() operation is deprecated and will be
dropped. Drop its usage from the pxa_camera driver, querying the sensor
bus configuration instead of setting it. Only the ov6650 driver supports
the operation, any platform that experiences issues with this change
should update the ov6650 configuration to match what pxa_camera
supports.

the smi-larb's pm_runtime_get_sync also be called automatically.
