We found a stability issue on MT8188 when connecting an external monitor
in 2560x1440@144Hz mode. Checked with the designer, there is a function
called "prefetch" which is working during VBP (triggered by VSYNC).
If the duration of VBP is too short, the throughput requirement could
increase more than 3 times and lead to stability issues.
The mode settings that VDOSYS supports are mainly affected by clock
rate and throughput, display driver should filter these settings
according to the SoC's limitation to avoid unstable conditions.
Since currently the mode filter is only available on MT8195 and MT8188
and they share the same compatible name, the reference number (8250)
is hard coded instead of in the driver data.

Different from OVL, OVL adaptor is a pseudo device so we didn't
define it in the device tree, consequently, pm_runtime_resume_and_get()
called by .atomic_enable() powers on no device. For this reason, we
implement a function to power on the RDMAs in OVL adaptor, and the
system will make sure the IOMMUs are powered on as well because of the
device link (iommus) in the RDMA nodes in DTS.
This patch separates power and clock management process, it would be
easier to maintain and add extensions.

Add dynamic select available connector flow in mtk_drm_crtc_create()
and mtk_drm_crtc_atomic_enable().
In mtk_drm_crtc_create(), if there is a connector routes array in drm
driver data, all components definded in the connector routes array will
be checked and their encoder_index will be set.
In mtk_drm_crtc_atomic_enable(), crtc will check its encoder_index to
identify which componet in the connector routes array should append.

Dpintf is the displayport interface hardware unit. This unit is similar
to dpi and can reuse most of the code.
This patch adds support for mt8195-dpintf to this dpi driver. Main
differences are:
- 4 pixels for one iteration for dp_intf while dpi is 1 pixel for one
iteration.
- Input of dp_intf is two pixels per iteration.
- Some register contents differ slightly between the two components.

We encountered a kernel panic issue that callback data will be NULL when
it's using in ovl irq handler. There is a timing issue between
mtk_disp_ovl_irq_handler() and mtk_ovl_disable_vblank().
To resolve this issue, we use the flow to register/unregister vblank cb:
- Register callback function and callback data when crtc creates.
- Unregister callback function and callback data when crtc destroies.
With this solution, we can assure callback data will not be NULL when
vblank is disable.
