drm/ttm: Add a generic TTM memcpy move for page-based iomem
The internal ttm_bo_util memcpy uses ioremap functionality, and while it
probably might be possible to use it for copying in- and out of
sglist represented io memory, using io_mem_reserve() / io_mem_free()
callbacks, that would cause problems with fault().
Instead, implement a method mapping page-by-page using kmap_local()
semantics. As an additional benefit we then avoid the occasional global
TLB flushes of ioremap() and consuming ioremap space, elimination of a
critical point of failure and with a slight change of semantics we could
also push the memcpy out async for testing and async driver development
purposes.
A special linear iomem iterator is introduced internally to mimic the
old ioremap behaviour for code-paths that can't immediately be ported
over. This adds to the code size and should be considered a temporary
solution.
Looking at the code we have a lot of checks for iomap tagged pointers.
Ideally we should extend the core memremap functions to also accept
uncached memory and kmap_local functionality. Then we could strip a
lot of code.

drm/sun4i: de3: Be explicit about supported modifiers
Currently only linear formats are supported in sun4i-drm driver, but
SoCs like H6 supports AFBC variant of some of them in multiple cores
(GPU, VPU, DE3). Panfrost already implements AFBC compression and is
sometimes confused what should be default choice (linear, AFBC) if DRM
driver is not explicit about modifier support (MiniMyth2 distro with
MythTV app).
After some discussion with Daniel Stone on #panfrost IRC, it was decided
to make modifiers in sun4i-drm explicit, to avoid any kind of guessing,
not just in panfrost, but everywhere. In fact, long term idea is to make
modifier parameter in drm_universal_plane_init() mandatory (non NULL).

The new gpiod interface takes care of parsing the GPIO flags and to

to it simplifies a lot the driver.

drm/vc4: hdmi: Fix error path of hpd-gpios
If the of_get_named_gpio_flags call fails in vc4_hdmi_bind, we jump to
the err_unprepare_hsm label. That label will then call
pm_runtime_disable and put_device on the DDC device.
We just retrieved the DDC device, so the latter is definitely justified.
However at that point we still haven't called pm_runtime_enable, so the
call to pm_runtime_disable is not supposed to be there.

drm/panfrost: Add AFBC_FEATURES parameter
The value of the AFBC_FEATURES register is required by userspace to
determine AFBC support on Bifrost. A user on our IRC channel (#panfrost)
reported a workload that raised a fault on one system's Mali G31 but
worked flawlessly with another system's Mali G31. We determined the
cause to be missing AFBC support on one vendor's Mali implementation --
it turns out AFBC is optional on Bifrost!
Whether AFBC is supported or not is exposed in the AFBC_FEATURES
register on Bifrost, which reads back as 0 on Midgard. A zero value
indicates AFBC is fully supported, provided the architecture itself
supports AFBC, allowing backwards-compatibility with Midgard. Bits 0 and
15 indicate that AFBC support is absent for texturing and rendering
respectively.
The user experiencing the fault reports that AFBC_FEATURES reads back
0x10001 on their system, confirming the architectural lack of AFBC.
Userspace needs this parameter to know to disable AFBC on that
chip, and perhaps others.
v2: Fix typo from copy-paste fail.
v3: Bump the UABI version. This commit was cherry-picked from another
series so chalking this up to a rebase fail.

drm/rockchip: dsi: remove extra component_del() call
commit cf6d100dd238 ("drm/rockchip: dsi: add dual mipi support") added
this devcnt field and call to component_del(). However, these both
appear to be erroneous changes left over from an earlier version of the

component_del() runs unconditionally and in addition to the
component_del() calls in dw_mipi_dsi_rockchip_host_detach(). The second
call fails to delete anything and produces a warning in dmesg.
If we look at the previous version of the patch[1], however, we see that
it had logic to calculate devcnt and call component_add() in certain
situations. This was removed in v6, and the fact that the deletion code
was not appears to have been an oversight.

drm/rockchip: dsi: move all lane config except LCDC mux to bind()
When we first enable the DSI encoder, we currently program some per-chip
configuration that we look up in rk3399_chip_data based on the device
tree compatible we match. This data configures various parameters of the
MIPI lanes, including on RK3399 whether DSI1 is slaved to DSI0 in a
dual-mode configuration. It also selects which LCDC (i.e. VOP) to scan
out from.
This causes a problem in RK3399 dual-mode configurations, though: panel
prepare() callbacks run before the encoder gets enabled and expect to be
able to write commands to the DSI bus, but the bus isn't fully
functional until the lane and master/slave configuration have been
programmed. As a result, dual-mode panels (and possibly others too) fail
to turn on when the rockchipdrm driver is initially loaded.
Because the LCDC mux is the only thing we don't know until enable time
(and is the only thing that can ever change), we can actually move most
of the initialization to bind() and get it out of the way early. That's
what this change does. (Rockchip's 4.4 BSP kernel does it in mode_set(),
which also avoids the issue, but bind() seems like the more correct
place to me.)
Tested on a Google Scarlet board (Acer Chromebook Tab 10), which has a
Kingdisplay KD097D04 dual-mode panel. Prior to this change, the panel's
backlight would turn on but no image would appear when initially loading
rockchipdrm. If I kept rockchipdrm loaded and reloaded the panel driver,
it would come on. With this change, the panel successfully turns on
during initial rockchipdrm load as expected.
The CDP DP component of the rockchip GPU driver requires firmware
so define MODULE_FIRMWARE for rockchip/dptx.bin so the details
are available in the module info.

If one of those drivers has registered a fbdev, then the fallback fbdev of
the DRM driver won't be bound to the framebuffer console. To avoid that,
remove any existing generic driver and take over the graphics device.
By doing that, the fb mapped to the console is switched correctly from the
early fbdev to the one registered by the rockchip DRM driver:

Also, there isn't a lot of value in adding these "drmfb" suffices to their

by a real fbdev driver or a DRM driver using the fbdev emulation.
What programs should be interested about is if there's a DRM device, and
there are better ways to query that info than reading this procfs entry.
