- Infrastructure work in amdkfd to prepare for VI support. This work mainly
includes separating modules into ASIC-specific functionality, adding
new properties that are relevant for VI, making sure that shared code is
reused, etc.
- Improve mechanism of submitting packets to HIQ (the kernel queue that amdkfd
uses to issue commands to the GPU). The driver used to verify that each CS
was read by the GPU. However, this proved to be both unnecessary and erroneous.
Therefore, we cancelled this verification.
- Moved initialization of compute VMIDs into radeon driver

The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e.
at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display
controller device.
The HLCDC block provides a single RGB output port, and only supports LCD
panels connection to LCD panels for now.
The atmel,panel property link the HLCDC RGB output with the LCD panel
connected on this port (note that the HLCDC RGB connector implementation
makes use of the DRM panel framework).
Connection to other external devices (DRM bridges) might be added later by
mean of a new atmel,xxx (atmel,bridge) property.

This patch completely removes the sync_with_hw() because it was broken and
actually there is no point of using it.
This function was used to:
- Make sure that the submitted packet to the HIQ (which is a kernel queue) was
read by the CP. However, it was discovered that the method this function used
to do that (checking wptr == rptr) is not consistent with how the actual CP
firmware works in all cases.
- Make sure that the queue is empty before issuing the next packet. To achieve
that, the function blocked amdkfd from continuing until the recently
submitted packet was consumed. However, the acquire_packet_buffer() already
checks if there is enough room for a new packet so calling sync_with_hw() is
redundant.

This patch fixes a minor bug in allocate_hqd(), where the loop run from the
next-to-allocate pipe until the number of pipes.
This is wrong because we need to consider the possibility where
next-to-allocate pipe is not 0, and thus, the for-loop only checks part of the
pipes and doesn't wrap-around, as it supposed to do.
Therefore, we add another counting variable to make sure we go over all the
pipes, regardless of where we start to look at the first iteration of the loop.
This bug only affected non-HWS mode. In HWS mode, the CP fw is responsible for
allocating the HQD.

This patch adds new kfd gtt sub-allocator functions that service the amdkfd
driver when it wants to use gtt memory.
The sub-allocator uses a bitmap to handle the memory area that was transferred
to it during init. It divides the memory area into chunks, according to chunk
size parameter.
The allocation function will allocate contiguous chunks from that memory area,
according to the requested size. If the requested size is smaller than the
chunk size, a single chunk will be allocated.

This patch adds the implementation of the gtt interface functions.
The allocate function will allocate a single bo, pin and map it to kernel
memory. It will return the gpu address and cpu ptr as arguments.
v2:
The bulk of the allocations in the GART is for MQDs. MQDs represent active
user-mode queues, which are on the current runlist. It is important to
remember that active queues doesn't necessarily mean scheduled/running
queues, especially if there is over-subscription of queues or more than a
single HSA process.
Because the scheduling of the user-mode queues is done by the CP firmware,
amdkfd doesn't have any indication if the queue is scheduled or not. If the
CP will try to schedule a queue, and its MQD is not present, this will
probably stuck the CP permanently, as it will load garbage from the GART
(the address of the MQD is given to the CP inside the runlist packet).
In addition, there are a couple of small allocations which also should
always be pinned - runlist packets (2 packets) and HPDs. runlist packets can
be quite large, depending on number of processes and queues.
This new allocate function represents the short/mid-term solution of limiting
the total memory consumption to around 4MB by default.
The long-term solution is to create a mechanism through which radeon/ttm can
ask amdkfd to clear GART/VRAM memory due to memory pressure.
Then, amdkfd will preempt the running queues and wait until the memory pressure
is over. After that, amdkfd will reschedule the queues.

Next batch of atomic work. Most important is the propertification from Rob
and the nth iteration of the actual atomic ioctl originally from Ville.
Big differences compared to earlier revisions:
- Core properties are now fully handled by the core, drivers can only
handle driver-specific properties.
- Atomic props&ioctl are opt-in per file_priv, userspace needs to
explicitly ask for it (like universal plane support).
- For now all hidden behind the atomic module option until this has
settled a bit.
- Atomic modesets are currently not possible since the exact abi for how
to handle the mode property is still under discussion.
Besides this some cleanup patches from me and the addition of per-object
state to global state backpointers to simplify drivers.

We do not need to track the state of the IPU DI's clock flags by having
each display bridge calling back into imx-drm-core, and then back out
into ipuv3-crtc.c.
ipuv3-crtc can instead just scan the list of encoders to retrieve their
type, and build up a picture of which types of encoders are attached.
We can then use this information to configure the IPU DI clocking mode
without any uncertainty - if we have multiple bridges connected to the
same DI, if one of them requires a synchronous DI clock, that's what we
must use.

On some monitors, high resolution modes are not working, exhibiting
pixel column truncation problems (for example, 1280x1024 displays as
1280x1022).
The function ipu_di_adjust_videomode() aims to fix these issues by
adjusting a passed videomode to IPU restrictions. The function can
be called from the drm_crtc_helper_funcs->mode_fixup() methods.
