mtk_mipi_tx is the phy of mtk_dsi.
mtk_dsi get the phy(mtk_mipi_tx) in probe().
So, mtk_mipi_tx init should be ahead of mtk_dsi. Or mtk_dsi will

Add mmap callback to struct drm_gem_object_funcs, which is supposed to
handle the vma setup. It will be used by both normal fops->mmap (via
drm_gem_mmap_obj()) and prime mmap (via drm_gem_prime_mmap()).
For starters the shmem and vram helpers are switched over to the new
workflow, to show things
Not obvious why this is needed. According to Deniel Vetter this is most
likely a historic artefact dating back to the days where drm drivers
exposed hardware registers as mmap'able gem objects, to avoid dumping
touching those registers. shmem gem objects surely don't need that ...

drm_gem_object_funcs->vm_ops alone can't handle everything which needs
to be done for mmap(), tweaking vm_flags for example. So add a new

Note that the vm_ops field is not used in case the mmap callback is
present, it is expected
Rename ttm_fbdev_mmap to ttm_bo_mmap_obj. Move the vm_pgoff sanity

Using a power-of-2 instead of power-of-10 base makes the computations
much cheaper. 2^16 is safe; retval never becomes more than 2^48 +
2^16/2. On a 32 bit platform, the very expensive 64/32 division at the
end of cie1931() instead becomes essentially free (a shift by 32 is
just a register rename).
The "break-even" point for the two formulas is L==8, which is also
what the code actually implements. [Incidentally, at that point one
has Y=0.008856, not 0.08856].
Moreover, all the sources I can find say the linear factor is 903.3
rather than 902.3, which makes sense since then the formulas agre
The scheduler uses a (currently private) fixed_power_int() in its load
average computation for computing powers of numbers 0 < x < 1
expressed as fixed-point numbers, which is also what we want here. But
that requires the scale to be a power-of-2.
We could (and a following patch will) change to us

Oh, I don't know why I stumbled upon and reviewed a patch that had

When the calculate scaling factors are out of range let's
print out the calculated value and the min/max. Should make
life a bit less confusing when decoding failure logs.
I decided to print them in decimal rather than hex. Not sure
which people prefer but maybe this is less
From: Ville Syrjälä
We may want to dump out the calculated scaling factor(s) when
they exceed the limits. To achieve that we need to return the
error code and scaling factor separately.
Side note: the code in dpu_plane_validate_multirect_v2()
looks rather dubious on account of it not using fixed

Dump out the plane/crtc id/name in the failure debug messages.
Makes a bit easier to figure out which plane exactly has failed
when you have tons of them.

The exynos-bus devfreq driver is extended with interconnect functionality
by a subsequent patch. This patch removes a check from the interconnect
framework that prevents interconnect from working on exynos-bus, in which
every bus is a separate interconnect provider.

It is expected that processes will pass dma-buf fd between drivers, and
only using the fd themselves for mmaping and synchronisation ioctls.
However, it may be convenient for an application to read/write into the
dma-buf, for instance a test case to check the internal
dma_buf->ops->kmap interface.
