Take a GEM reference for and pin the new cursor BO, unpin and drop the
GEM reference for the old cursor BO in dce11 crtc_cursor_set2, and use
amdgpu_crtc->cursor_addr in dce11 set_cursor.
This fixes dce11 cursor_reset accidentally incrementing the cursor BO
pin count, and cleans up the code a little.

The cursor_set2 hook provides the cursor hotspot position within the
cursor image. When the hotspot position changes, we can adjust the cursor
position such that the hotspot doesn't move on the screen. This prevents
the cursor from appearing to intermittently jump around on the screen
when the position of the hotspot within the cursor image changes.

There doesn't seem to be any need to have 'ib' volatile, the code is
not even consistent with it and some places already miss it. As it is
now it's just making gcc produce worse code. If there are special
requirements for that memory, then proper primitives like memory
barriers or accessor functions should be used, but it doesn't look
like that is needed here.
While at it, change the type to match the one in radeon_ib structure.

After this patch the register check loop does the same thing as before,
except that now gcc does better job optimizing it: it now sees that
end_reg was already checked against PACKET3_SET_CONTEXT_REG_END and can
optimize REG_SAFE_BM_SIZE comparison out of evergreen_is_safe_reg()
as (PACKET3_SET_CONTEXT_REG_END >> 7) < REG_SAFE_BM_SIZE.

evergreen_cs_check_reg() is a large function and gcc doesn't want to
inline it. It has a quick check for reg_safe_bm[] to see if register
needs special handling, which often results in early exit. However
because the function is large, it has a long prologue/epilogue to
save/restore all the callee-save registers which according to perf is
taking significant amount of time. To avoid this, we can reuse
evergreen_is_safe_reg() to do the early check directly in register loop.

To avoid having to distinguish between CAYMAN or older on every register
check, place a pointer in evergreen_cs_track and use it unconditionally.
Also make use of the fact that both reg_safe_bm[] arrays are of the same
length to remove another CAYMAN check.

As reading the interrupt registers clears the outstanding interrupts, we
must process all received interrupts to avoid dropping any. Rearrange
the code to achieve this, and properly check for a HPD interrupt from
the CEC_RXSHPDINT register.

Commit 6833d26ef823 ("drm: tda998x: Fix EDID read timeout on HDMI
connect") used a weak scheme to try and delay reading EDID on a HDMI
connect event. It is weak because delaying the notification of a
hotplug event does not stop userspace from trying to read the EDID
within the 100ms delay.
The solution provided here solves this issue:
* When a HDMI connection event is detected, mark a blocking flag for
EDID reads, and start a timer for the delay.
* If an EDID read is attempted, and the blocking flag is set, wait
for the blocking flag to clear.
* When the timer expires, clear the blocking flag and wake any thread
waiting for the EDID read.

Rather than always reporting that the interrupt was handled, we should
report whether we did handle the interrupt. Arrange to report IRQ_NONE
for cases where we found nothing to do.
This allows us to (eventually) recover from stuck-IRQ problems, rather
than causing the kernel to solidly lock up.

There is no way 'priv' can be NULL in tda998x_irq_thread() - this can
only happen if request_threaded_irq() was passed a NULL priv pointer,
and we would have crashed long before then if that was the case.
We also always ensure that priv->encoder is correctly setup, which
must have been initialised prior to the interrupt being claimed, so we
can remove this check as well.

* remove support for the non-component support from the Armada DRM driver,
switching it to component-only mode.
* create a "armada plane" to allow the primary and overlay planes to share
some code.
* increase efficiency by using inherently atomic operations, rather than
spinlocking to achieve atomicity. Eg, if we want to exchange a value,
using xchg().
* increase PM savings by stopping the external pixel clock when we're in
DPMS mode.

Add a plane work implementation, and move the CRTC framebuffer flip
work to it for the primary plane. The idea is to have a common

Both the CRTC and overlay frames have their own wait queues. It would
make more sense if these were part of the plane - the primary plane for
the CRTC and overlay plane for the overlay.

It is not necessary to write dplane->ctrl0 under the CRTC spinlock, as
this is only accessed under process context where the DRM locks will
protect us instead.
