In order to avoid any probe ordering issue, the best practice is to move

Since commit 875a4d536842 ("drm/vc4: drv: Disable the CRTC at boot
time"), during the initial setup of the driver we call into the VC4 HDMI
controller hooks to make sure the controller is properly disabled.
However, we were never making sure that the device was properly powered
while doing so. This never resulted in any (reported) issue in practice,
but since the introduction of commit 4209f03fcb8e ("drm/vc4: hdmi: Warn
if we access the controller while disabled") we get a loud complaint
when we do that kind of access.
Let's make sure we have the HDMI controller properly powered while
disabling it.

Similarly to what we encountered with the detect hook with DRM, nothing
actually prevents any of the CEC callback from being run while the HDMI
output is disabled.
However, this is an issue since any register access to the controller
when it's powered down will result in a silent hang.
Let's make sure we run the runtime_pm hooks when the CEC adapter is
opened and closed by the userspace to avoid that issue.

In order to access the HDMI controller, we need to make sure the HSM
clock is enabled. If we were to access it with the clock disabled, the
CPU would completely hang, resulting in an hard crash.
Since we have different code path that would require it, let's move that
clock enable / disable to runtime_pm that will take care of the
reference counting for us.
Since we also want to change the HSM clock rate and it's only valid
while the clock is disabled, we need to move the clk_set_min_rate() call
on the HSM clock above pm_runtime_get_and_sync().

The driver, once it found a divider, tries to round it up by increasing
the least significant bit of the fractional part by one when the
round_up argument is set and there's a remainder.
However, since it increases the divider it will actually reduce the
clock rate below what we were asking for, leading to issues with
clk_set_min_rate() that will complain that our rounded clock rate is
below the minimum of the rate.
Since the dividers are fairly precise already, let's remove that part so
that we can have clk_set_min_rate() working.
This is effectively a revert of 9c95b32ca093 ("clk: bcm2835: add a round

Just exercising a very minor subset of the functionality, but already
proven useful.
v2: add missing locking
v3: some more cleanup and consolidation, add unlocked test as well
v4: add a dma_resv_get_fences selftest

Simplifying the code a bit.
The new implementation unifies the handling between drivers and so
results in waiting for all shared fernces in all cases.

Moving the driver-specific mmap code into a GEM object function allows
for using DRM helpers for various mmap callbacks.
The respective rockchip functions are being removed. The file_operations
structure fops is now being created by the helper macro
DEFINE_DRM_GEM_FOPS().

Driver never uses virtual address of DRM CMA buffers. Switch to CMA
helpers which don't deal with virtual mapping.
This was actually already the case before commit ad408c766cef
("drm/sun4i: Use DRM_GEM_CMA_VMAP_DRIVER_OPS for GEM operations"),
but only convenient macro at the time used helpers with virtual
mapping.

Gma500 currently removes generic fbdev drivers, but ignores
generic DRM drivers. Use aperture helpers to remove all generic
graphics drivers before loading gma500. Makes gma500 compatible
with simpledrm.
