Those macros are really about the HVS itself, and thus its associated
structure vc4_hvs, rather than the entire (virtual) vc4 device.

Let's change those macros to use the hvs pointer directly, and change
the calling sites accordingly.

atomic_flush will be called for each CRTC even if they aren't enabled.

The whole code we have there will thus run without a properly affected
channel, which can then result in all sorts of weird behaviour.

Fortunately, the DRM_PLANE_COMMIT_ACTIVE_ONLY flag will skip the CRTC
atomic_begin and atomic_flush, and the planes atomic_update, if they
aren't enabled.

Our plane atomic_update is a nop, and atomic_begin will copy the current
HVS channel to the vc4_crtc structure for the interrupt handler to
consume, but the handler won't run if the CRTC is disabled. So in the
end, it will only skip our CRTC atomic_flush, which is what we want.

The vc4_hvs_update_dlist function mostly deals with setting up the
vblank events and setting up the dlist entry pointer to our current
active one.

We'll want to do the former separately from the vblank handling in later
patches, so let's move it to a function of its own.

In order to get the field currently being output, the driver has been
using the display FIFO frame count in the HVS, reading a 6-bit field at
the offset 12 in the DISPSTATx register.

While that field is indeed at that location for the FIFO 1 and 2, the
one for the FIFO0 is actually in the DISPSTAT1 register, at the offset
18.

During a commit, the core clock, which feeds the HVS, needs to run at
a minimum of 500MHz.

While doing that commit, we can also change the mode to one that
requires a higher core clock, so we take the core clock rate associated
to that new state into account for that boost.

However, the old state also needs to be taken into account if it
requires a core clock higher that the new one and our 500MHz limit,
since it's still live in hardware at the beginning of our commit.

The datasheet for this bridge is not available, the PLL behavior has been
inferred from [1] and [2] and by analyzing the DPI pixel clock with scope.
After further testing with other displays and different DSI data lane count,
it turns out the P-factor is not 1/2^N divider, but rather only 1/N divider.
It also turns out the input into the PLL seem to be ByteClock instead of DSI
HS clock.

Rework the P-factor calculation such that the PLL calculation code handles
P-factor from 1..32 with P-factors above 16 must be even. In case P-factor
is even, enable built-in 1:2 divider and program P-factor/2 to PLL_REF_DIV,
otherwise configure only the P-factor into PLL_REF_DIV register.

Switch the PLL factor calculation from kHz to Hz to maintain precision.

The bug is here:
	if (nvkm_cstate_valid(clk, cstate, max_volt, clk->temp))
		return cstate;

The list iterator value 'cstate' will *always* be set and non-NULL
by list_for_each_entry_from_reverse(), so it is incorrect to assume
that the iterator value will be unchanged if the list is empty or no
element is found (In fact, it will be a bogus pointer to an invalid
structure object containing the HEAD). Also it missed a NULL check
at callsite and may lead to invalid memory access after that.

To fix this bug, just return 'encoder' when found, otherwise return
NULL. And add the NULL check.
