The atombios tables have an unfortunate restriction on only
being able to write 12 bytes, MST really wants 16-bytes here,
and since the hw can do it, we should just write directly to it.
This uses a module option to allow for it now, and maybe
we should provide the old code as a fallback for a while.

- move registers to a proper register header
- only enable on DCE5+
- enable by default on DCE5+
- Switch pad to aux mode before using it
- reformat instance handling to better match the
rest of the driver

This allows us to query certain registers from userspace

This adds a callback for each asic family to determine what
registers are allowed to be read back via the info ioctl.
The idea here is to allow usermode to query things like GPU status
registers or GPU harvest registers for profiling and determining

This adds the drm property for output csc (e.g.,
transform of output display colorspace). Currently
only common ones (TV RGB, BT.601, BT.709) are supported,
but bypass and tv rgb are really the only useful ones at
the moment. Additionally we could expose a user adjustable
matrix in the future.
This commit just adds the property. The hw support will
be added in subsequent patches.

drm/rockchip: vop: power off until vop standby take effect
drm/rockchip: vop: set vop enabled after enable iommu
drm/rockchip: vop use is_enabled instead of dpms mode
drm/rockchip: vop: fix vop vsync/hsync polarity

Another drm-misch pull request. Mostly the fbdev sizes deconfusion series

This wasn't too harmful since we already look at connector,
which has the same effect as the loop for any non-cloned configs.
Only when we have a cloned configuration is it important to look
at other connectors. Furthermore existing userspace always changes
dpms on all of them anyway.

Vop standby will take effect at end of current frame,
if dsp_hold_valid_irq happen, it means vop standby complete.
we must wait standby complete when we want to disable aclk,
if not, memory bus maybe dead.

there is a Bug that:
vop_enable()->drm_vblank_on, drm_vblank_on may call vop
enable vblank. if it happen, vblank enable would failed,
then cause irq status error. because is_enabled value is set
after drm_vblank_on.
after enable vop clocks and iommu regs, we can sure that
R/W vop regs and do vop plane flip is safe, so place
is_enabled = true after enable iommu is suitable.

drm dpms have many power modes: ON,OFF,SUSPEND,STANDBY, etc.
but vop only have enable/disable mode, maybe case such bug:
--> DRM_DPMS_ON: power on vop
--> DRM_DPMS_SUSPEND: power off vop
--> DRM_DPMS_OFF: already power off at SUSPEND, crash
so use a bool val is more suitable.

In general, the data in drm/rockchip GEM objects is never accessed by
the kernel. The objects are either accessed by a GPU, by display
controller DMA, or by mmap'ing them to user space. Thus, these
buffers need not be mapped into kernel address space.
The only exception is the fbdev framebuffer(s), which may be written
in-kernel by fbcon.
