drm/meson: dw-hdmi: Ensure that clocks are enabled before touching the TOP registers
Removing the meson-dw-hdmi module and re-inserting it results in a hang
as the driver writes to HDMITX_TOP_SW_RESET. Similar effects can be seen
when booting with mainline u-boot and using the u-boot provided DT (which
is highly desirable).
The reason for the hang seem to be that the clocks are not always
enabled by the time we enter meson_dw_hdmi_init(). Moving this call
*after* dw_hdmi_probe() ensures that the clocks are enabled.
as the HDMI regulator is still enabled on release.
In order to address this, register a callback that will deal with
the disabling when the driver is unbound, solving the problem.

fbcon: Disable accelerated scrolling
So ever since syzbot discovered fbcon, we have solid proof that it's
full of bugs. And often the solution is to just delete code and remove
features, e.g. 50145474f6ef ("fbcon: remove soft scrollback code").
Now the problem is that most modern-ish drivers really only treat
fbcon as an dumb kernel console until userspace takes over, and Oops
printer for some emergencies. Looking at drm drivers and the basic
vesa/efi fbdev drivers shows that only 3 drivers support any kind of
acceleration:
- nouveau, seems to be enabled by default
- omapdrm, when a DMM remapper exists using remapper rewriting for
y/xpanning
- gma500, but that is getting deleted now for the GTT remapper trick,
and the accelerated copyarea never set the FBINFO_HWACCEL_COPYAREA
flag, so unused (and could be deleted already I think).
No other driver supportes accelerated fbcon. And fbcon is the only
user of this accel code (it's not exposed as uapi through ioctls),
which means we could garbage collect fairly enormous amounts of code
if we kill this.
Plus because syzbot only runs on virtual hardware, and none of the
drivers for that have acceleration, we'd remove a huge gap in testing.
And there's no other even remotely comprehensive testing aside from
syzbot.
This patch here just disables the acceleration code by always
redrawing when scrolling. The plan is that once this has been merged
for well over a year in released kernels, we can start to go around
and delete a lot of code.

This is unsatisfactory. In fact, there is already a `charcount` field in
our virtual console descriptor (see `struct console_font` inside `struct
vc_data`), let us use it:
map.length = vc->vc_font.charcount;
Recently we added a `charcount` field to `struct font_desc`. Use it to set
`vc->vc_font.charcount` properly. The idea is:
- We only use FNTCHARCNT() on `vc->vc_font.data` and `p->fontdata`.
Assume FNTCHARCNT() is working as intended;
- Whenever `vc->vc_font.data` is set, also set `vc->vc_font.charcount`
properly;
- We can now replace `FNTCHARCNT(vc->vc_font.data)` with
`vc->vc_font.charcount`;
- Since `p->fontdata` always point to the same font data buffer with
`vc->vc_font.data`, we can also replace `FNTCHARCNT(p->fontdata)` with
`vc->vc_font.charcount`.
In conclusion, set `vc->vc_font.charcount` properly in fbcon_startup(),
fbcon_init(), fbcon_set_disp() and fbcon_do_set_font(), then replace
FNTCHARCNT() with `vc->vc_font.charcount`. No more if-else between
negative-indexing macros and hard-coded values.
Do not include <linux/font.h> in fbcon_rotate.c and tileblit.c, since they
no longer need it.

console: Delete dummy con_font_set() and con_font_default() callback implementations
.con_font_set and .con_font_default callbacks should not pass `struct

structure.
We are trying to let them use our new kernel font descriptor, `struct
font_desc` instead. To make that work slightly easier, first delete all of
their no-op implementations used by dummy consoles.
This will make KD_FONT_OP_SET and KD_FONT_OP_SET_DEFAULT ioctl() requests

since no user should ever expect such operations to succeed on dummy
consoles.

drm/ingenic: ipu: Search for scaling coefs up to 102% of the screen
Increase the scaled image's theorical width/height until we find a
configuration that has valid scaling coefficients, up to 102% of the
screen's resolution. This makes sure that we can scale from almost
every resolution possible at the cost of a very small distorsion.
The CRTC_W / CRTC_H are not modified.
This algorithm was already in place but would not try to go above the
screen's resolution, and as a result would only work if the CRTC_W /
CRTC_H were smaller than the screen resolution. It will now try until it
reaches 102% of the screen's resolution.
Note that this algorithm exists mostly as a band-aid for a missing
functionality: it is not possible for userspace to request the closest
mode that would encapsulate the provided one, because the GEM buffer is
created beforehand. If there was a way to let the kernel tweak the mode,
I could write a better algorithm that would result in a better looking
picture.

drm/ttm: add multihop infrastrucutre (v3)
Currently drivers get called to move a buffer, but if they have to
move it temporarily through another space (SYSTEM->VRAM via TT)
then they can end up with a lot of ttm->driver->ttm call stacks,
if the temprorary space moves requires eviction.
Instead of letting the driver do all the placement/space for the
temporary, allow it to report back (-EMULTIHOP) and a placement (hop)
to the move code, which will then do the temporary move, and the
correct placement move afterwards.
This removes a lot of code from drivers, at the expense of
adding some midlayering. I've some further ideas on how to turn
it inside out, but I think this is a good solution to the call
stack problems.
v2: separate out the driver patches, add WARN for getting
MULTHOP in paths we shouldn't (Daniel)
v3: use memset (Christian)

drm: remove pgprot_decrypted() before calls to io_remap_pfn_range()
commit f8f6ae5d077a ("mm: always have io_remap_pfn_range() set
pgprot_decrypted()") moves the pgprot_decrypted() into
io_remap_pfn_range(). Delete any, now confusing, open coded calls that
directly precede io_remap_pfn_range():
- drm_io_prot() is only in drm_mmap_locked() to call io_remap_pfn_range()
- fb_mmap() immediately calls vm_iomap_memory() which is a convenience
wrapper for io_remap_pfn_range()
drm: DRM_KMB_DISPLAY should depend on ARCH_KEEMBAY
The Intel Keem Bay display controller is only present on Intel Keem Bay
SoCs. Hence add a dependency on ARCH_KEEMBAY, to prevent asking the
user about this driver when configuring a kernel without Intel Keem Bay
platform support.
Note that:
1. The dependency on ARM is dropped, as Keem Bay SoCs are only
supported in arm64 kernel builds,
2. The dependencies on OF and COMMON_CLK can be dropped for
compile-testing, as the driver builds fine regardless.

drm/omap: Fix runtime PM imbalance on error
pm_runtime_get_sync() increments the runtime PM usage counter
even when it returns an error code. However, users of its
direct wrappers in omapdrm assume that PM usage counter will
not change on error. Thus a pairing decrement is needed on
the error handling path for these wrappers to keep the counter
balanced.
