It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

There are 2 banks on it6505, and when writing to different bank,
REG_BANK_SEL needs to be set to the targeted bank. The current code set
this additionally, which causes a race condition when a process is
writing bank 0 registers while another process set the bank to 1. Set
ranges in regmap config so the regmap API would handle the bank changes.

The "mediatek,mt8183-mali" compatible uses platform data that calls for
getting (and managing) two regulators ("mali" and "sram") but devfreq
does not support this usecase, resulting in DVFS not working.
Since a lot of MediaTek SoCs need to set the voltages for the GPU SRAM
regulator in a specific relation to the GPU VCORE regulator, a MediaTek
SoC specific driver was introduced to automatically satisfy, through
coupling, these constraints: this means that there is at all no need to
manage both regulators in panfrost but to otherwise just manage the main
"mali" (-> gpu vcore) regulator instead.
Keeping in mind that we cannot break the ABI, the most sensible route
(avoiding hacks and uselessly overcomplicated code) to get a MT8183
node with one power supply was to add a new "mediatek,mt8183b-mali"
compatible, which effectively deprecates the former.

The sram-supply part is left in place to be disallowed for anything

is MediaTek-specific and it is, and will ever be, used only for this
specific string due to the addition of the mediatek-regulator-coupler

Remove all codepaths that implement fbdev output directly on GEM
buffers. Always allocate a shadow buffer in system memory and set
up deferred I/O for mmap.
The fbdev code that operated directly on GEM buffers was used by
drivers based on GEM DMA helpers. Those drivers have been migrated
to use fbdev-dma, a dedicated fbdev emulation for DMA memory. All
remaining users of fbdev-generic require shadow buffering.
Memory management of the remaining callers uses TTM, GEM SHMEM
helpers or a variant of GEM DMA helpers that is incompatible with
fbdev-dma. Therefore remove the unused codepaths from fbdev-generic
and simplify the code.
Using a shadow buffer with deferred I/O is probably the best case
for most remaining callers. Some of the TTM-based drivers might
benefit from a dedicated fbdev emulation that operates directly on
the driver's video memory.

Commit 45d9c8dde4cd ("drm/vgem: use shmem helpers") introduced shmem
helpers to vgem and with that, removed all uses of the struct
drm_vgem_gem_object. So, as the struct is no longer used, delete it.

The DRM device passed to drm_gem_prime_fd_to_handle() is where the
dma-buf is being imported, not the device where it was exported.
Also fix a trivial typo in drm_gem_prime_import_dev().

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
