[Why]
drm_atomic_helper_check_crtc now verifies both legacy and non-legacy LUT
sizes. There is no need to check it within amdgpu_dm_atomic_check.

[Why]
1. drm_atomic_helper_check doesn't check for the LUT sizes of either Gamma
or Degamma props in the new CRTC state, allowing any invalid size to
be passed on.
2. Each driver has its own LUT size, which could also be different for
legacy users.

This function and enum do not do generic checking on the luts but they

Conventionally, panel is listed under the root of 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 panel under "aux-bus" of ps8640
bridge node in the device tree. In thi
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
proxied by GPIO9) (3) the other configs. As runtime_resume() can be
called before panel is powered, we on

Attach a top-level bridge to each encoder, which will be used for
negociating the bus format and flags.
All the bridges are now attached with DRM_BRIDGE_ATTACH_NO_CONNECTOR.

When using C8 color mode, make sure that the palette is always uploaded
before a frame; otherwise the very first frame will have wrong colors.
Do that by changing the link order of the DMA descriptors.

ingenic_drm_get_priv_state()

Setting the DMA descriptor chain register in the probe function has been
fine until now, because we only ever had one descriptor per foreground.
As the driver will soon have real descriptor chains, and the DMA
descriptor chain register updates itself to point to the current
descriptor being proces

drm/ingenic: Simplify code by using hwdescs array

The IPU scaling information is computed in the plane's ".atomic_check"
callback, and used in the ".atomic_update" callback. As such, it is
state-specific, and should be moved to a private state structure.

Until now, the ingenic-drm as well as the ingenic-ipu drivers used to
put state-specific information in their respective private structure.
Add boilerplate code to support private objects in the two drivers, so
that state-specific information can be put in the state-specific private
structure.

Instead of having one 'hwdesc' variable for the plane #0, one for the
plane #1 and one for the palette, use a 'hwdesc[3]' array, where the
DMA hardware descriptors are indexed by the plane's number.
v2: dma_hwdesc_addr() extended to support palette hwdesc. The palette
hwdesc is now hwdesc[3] t
