The OnSemi FIN3385 Parallel-to-LVDS encoder has a dedicated input line to
select input pixel data sampling edge. Add DT property "pclk-sample", not
the same as the one used by display timings but rather the same as used by
media, and configure bus flags based on this DT property.

The mxsfb->crtc.funcs may already be NULL when unloading the driver,
in which case calling mxsfb_irq_disable() via drm_irq_uninstall() from

Since all we care about is masking the IRQ and mxsfb->base is still

Conventionally, panel is listed under the root in the device tree.
When userland asks for display mode, ps8640 bridge is responsible
for returning EDID when ps8640_bridge_get_edid() is called.
Now enable a new option of listing the panel under "aux-bus" of ps8640

Fit ps8640 driver into runtime power management framework:
First, break _poweron() to 3 parts: (1) turn on power and wait for
ps8640's internal MCU to finish init (2) check panel HPD (which is
proxy by GPIO9) (3) the other configs. Runtime _resume() can be called
