dcss currently allocates and ioremaps quite a few resources in its probe
function's call graph. Devres now provides convenient functions which
perform the same task but do the cleanup automatically.
Port all memory allocations and ioremap() calls to the devres
counterparts.

The driver's memory regions are currently just ioremap()ed, but not
reserved through a request. That's not a bug, but having the request is
a little more robust.
Implement the region-request through the corresponding managed
devres-function.

The cleanup can be dispatched while the atomic update is still active,
which means that the memory acquired in the atomic update needs to
not be invalidated by the cleanup. The buffer objects in vmw_plane_state
instead of using the builtin map_and_cache were trying to handle
the lifetime of the mapped memory themselves, leading to crashes.

When a Loongson laptop is equipped with a Radeon GPU, it can be true that
there is no dedicated VRAM soldered on the motherboard. This is probably
for cost reason, but drm/loongson driver is probed because the platform
BIOS (either UEFI or PMON) forget to disable the integrated GPU.
So in the lsdc_get_dedicated_vram() function, we error out if no dedicated
VRAM detected. This fix nothing, but serve as a sanity check only.

Some drivers require the mapped tt pages to be decrypted. In an ideal
world this would have been handled by the dma layer, but the TTM page
fault handling would have to be rewritten to able to do that.
A side-effect of the TTM page fault handling is using a dma allocation
per order (via ttm_pool_alloc_page) which makes it impossible to just
trivially use dma_mmap_attrs. As a result ttm has to be very careful
about trying to make its pgprot for the mapped tt pages match what
the dma layer thinks it is. At the ttm layer it's possible to
deduce the requirement to have tt pages decrypted by checking
whether coherent dma allocations have been requested and the system
is running with confidential computing technologies.
This approach isn't ideal but keeping TTM matching DMAs expectations
for the page properties is in general fragile, unfortunately proper
fix would require a rewrite of TTM's page fault handling.
Fixes vmwgfx with SEV enabled.

vmw_context_cotable can return either an error or a null pointer and its
usage sometimes went unchecked. Subsequent code would then try to access
either a null pointer or an error value.
The invalid dereferences were only possible with malformed userspace

The issue here is as follows:
- tidss probes, but is deferred as sii902x is still missing.
- sii902x starts probing and enters sii902x_init().
- sii902x calls drm_bridge_add(). Now the sii902x bridge is ready from
DRM's perspective.
- sii902x calls sii902x_audio_codec_init() and
platform_device_register_data()
- The registration of the audio platform device causes probing of the
deferred devices.
- tidss probes, which eventually causes sii902x_bridge_get_edid() to be
called.
- sii902x_bridge_get_edid() tries to use the i2c to read the edid.
However, the sii902x driver has not set up the i2c part yet, leading
to the crash.
Fix this by moving the drm_bridge_add() to the end of the
sii902x_init(), which is also at the very end of sii902x_probe().

The synaptics-r63353 (panel-bridge) can only be configured in command mode.
So, samsung-dsim (bridge) must not be in display mode during the
prepare()/unprepare() of the panel-bridge. Setting the
"pre_enable_prev_first" flag to true allows the prepare() of the
panel-bridge to be called between the pre_enabled() and enabled() of the
bridge. So, the bridge can enter display mode only in the enabled().
The unprepare() of the panel-bridge is instead called between the disable()
and post_disable() of the bridge. So, the disable() must exit the display
mode (i .e. enter command mode) to allow the panel-bridge to receive DSI
commands.
samsung_dsim_atomic_pre_enable -> command mode
r63353_panel_prepare -> send DSI commands

This patch replaces max(a, min(b, c)) by clamp(b, a, c) in the solo6x10
driver. This improves the readability and more importantly, for the
solo6x10-p2m.c file, this reduces on my system (x86-64, gcc 13):
- the preprocessed size from 121 MiB to 4.5 MiB;
- the build CPU time from 46.8 s to 1.6 s;
- the build memory from 2786 MiB to 98MiB.
In fine, this allows this relatively simple C file to be built on a
32-bit system.

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.
Error checking for matching and match data was not necessary as matching
is always successful if we're already in probe and the match tables always
have data pointers.
