Add support for the i.MX95 MIPI CSI-2 receiver. The i.MX95 variant is
nearly identical to i.MX93, with the main difference being the use of
IDI (Image Data Interface) instead of IPI (Image Pixel Interface).
However, the IDI interface is transparent to software, requiring only
a different register map definition while sharing the same PHY control
functions with i.MX93.

Implement waiting for D-PHY lanes to enter stop state on i.MX93. This
ensures proper PHY initialization by verifying that the clock lane and
all active data lanes have entered the stop state before proceeding with
further operations.

The current driver only supports single stream operation. Add support
for multiple concurrent streams by tracking enabled streams with a
bitmask and only initializing the hardware once for the first stream.
This enables use cases such as surround view systems where multiple
camera streams need to be processed simultaneously through the same
CSI-2 receiver interface.

The imx93_csi2rx_dphy_ipi_enable() function configures the IPI datatype
using csi2->formats->csi_dt, which is initialized during probe but never
updated in set_fmt(). This causes the IPI to always use the probe-time
default datatype, ignoring the actual media bus format negotiated at
runtime. When userspace requests a different format, the IPI hardware is
configured with the wrong datatype, resulting in incorrect image output.
Fix by updating csi2->formats in the set_fmt callback to reflect the
currently negotiated format, ensuring the IPI configuration matches the
runtime datatype.

The current implementation of alvium_ctrl_init creates several controls in
function alvium_ctrl_init and uses the returned pointer without check. That
can cause write access over NULL-pointer for several controls. The reworked
code checks the pointers before adding flags.

There are memory leaks in
drivers/staging/media/atomisp/pci/atomisp_compat_css20.c.
In atomisp_css_allocate_stat_buffers(), s3a_map is allocated by
ia_css_isp_3a_statistics_map_allocate() and its backing memory is
mapped via hmm_vmap(). When dis_buf allocation fails, the error path
frees s3a_data but does not unmap or free s3a_map. Similarly, when
md_buf allocation fails, neither s3a_map nor dvs_map (and their hmm
vmaps) are freed.
Add the missing hmm_vunmap() and map free calls on both error paths,
matching the cleanup order used in atomisp_css_free_3a_buffer() and
atomisp_css_free_dis_buffer().

Replace open-coded width * height * sizeof() multiplications with
array3_size() to prevent integer overflow in buffer allocations.
The atomisp driver computes DVS, morphing table, shading table and
statistics buffer sizes using unchecked arithmetic. When dimensions
are attacker-controlled or simply large, the product can silently wrap,
causing kvmalloc() to allocate an undersized buffer.
array3_size() saturates to SIZE_MAX on overflow, so kvmalloc() returns
NULL instead of succeeding with too few bytes.

In all cases in which a struct acpi_driver is used for binding a driver
to an ACPI device object, a corresponding platform device is created by
the ACPI core and that device is regarded as a proper representation of
underlying hardware. Accordingly, a struct platform_driver should be
used by driver code to bind to that device. There are multiple reasons
why drivers should not bind directly to ACPI device objects [1].
Overall, it is better to bind drivers to platform devices than to their
ACPI companions, so convert cmpc_keys_acpi_driver in the Classmate
laptop driver from an ACPI driver to a platform one.
After this change, the input device registered by the driver will appear
under the platform device used for driver binding.
While this is not expected to alter functionality, it changes sysfs
layout and so it will be visible to user space.

Every platform driver can be forced to match a device that doesn't match
its list of device IDs because of device_match_driver_override(), so
platform drivers that rely on the existence of a device's ACPI companion
object need to verify its presence.
Accordingly, add a requisite ACPI_COMPANION() check against NULL to the
platform/x86 system76 driver.
