The modetest application uses libkms to allocate dumb buffers, leading
to overallocation due to the hardcoded 32 bpp value. This can even cause
failures in drivers when the resulting pitch is too large for the
hardware to handle and gets rejected by the driver when creating the
frame buffer.

If no best divider is normally found, we will try to use the maximum divider.
We should not set the parent clock rate to be 1Hz by force for being rounded.
Instead, we should take the maximum divider as a base and calculate a correct

Why even try doing this if you know upfront that it can't be done. You
know much earlier than this that you can't drive the pixel format, why
not abort then?
People are much more likely to notice that the panel isn't supported if
the DSI output doesn't even show up (or doesn't expose any modes) rather
than if they have to find this error message in dmesg.

You probably want to parameterize based on the DSI peripheral's flags. I
see that you do reject devices with any other modes, so this may not be
necessary now. Out of curiosity, the hardware supports other modes,
right?

Hi,
Many kernel frameworks that uses provider/consumer schema suffer from
few issues:
1. They have broken driver unbinding handling. When device driver of the

track is a generic framework for safe tracking presence of any kernel objects
having an id. There are no special requirements about type of object or its

Typical usage of the framework by consumer looks as follow:
1. Consumer registers notifier callback for objects with give
restrack framework allows tracking presence of resources with dynamic life
time. Typical example of such resources are all resources provided by device
drivers, for example clocks, phys, regulators. Since drivers can be bound and
unbound dynamically and unconditionally, resources provided by such d

- correctly handles removal of resources,
- do not need to defer probing, so as a result the whole drm system
initialization will not be postponed to late initcall, unless other
components delays it,
-
The patch removes private of_graph functions and uses common ones.

exynos_dpi implements drm encoder and connector. Currently its probe
was defered if the associated panel was not yet present. It is inefficient
behavior - it could start normally with connector status set to disconnected
and notify drm about status change when panel appears/disapeears.
Unfortunatel
Panel is powered off already by connector during drm_panel_remove call.

Convert ld9040 panel driver to use restrack API.
As a result driver have following advantages:
- correctly handles removal of resources,
- do not need to defer probing, so as a result the panel
becomes available as soon as possible, in case of deferred
probing it was late_initcall,
- simplified

it's quite ugly and surprising.

Add implementations for drm_clflush_*() on ARM by borrowing code from
the DMA mapping API implementation. Unfortunately ARM doesn't export an
API to flush caches on a page by page basis, so this replicates most of
the code.

In DRM/KMS we are lacking a good way to deal with tiled/compressed

we cannot always rely on under-the-hood flags passed to driver specific
gem-create ioctl to pass around these extra flags.
