When trying to get the display up on my sdm845 board I noticed that
the display wouldn't probe if I had the dsi1 node marked as "disabled"
even though my board doesn't use dsi1. It looks like the msm code
adds all nodes to its list of components even if they are disabled. I
believe this doesn't work because all registered components need to
come up before we finish probing. Let's do like other DRM code and
only add available components.

SDM845 SoC includes the Mobile Display Sub System (MDSS) which is a
top level wrapper consisting of Display Processing Unit (DPU) and
display peripheral modules such as Display Serial Interface (DSI)
and DisplayPort (DP).
MDSS functions essentially as a back-end composition engine. It blends
video and graphic images stored in the frame buffers and scans out the
composed image to a display sink (over DSI/DP).
The following diagram represents hardware blocks for a simple pipeline
(two planes are present on a given crtc which is connected to a DSI
connector):
MDSS

| | +--------+ +--------+ | |
| | | SSPP | | SSPP | | |

| | +-----+ +-----+ | |
| +----------------------------+ |
+---------------------------------+
The number of DPU sub-blocks (i.e. SSPPs, LMs, PP blocks and INTFs)
depends on SoC capabilities.
Overview of DPU sub-blocks:
---------------------------
* Source Surface Processor (SSPP):
Refers to any of hardware pipes like ViG, DMA etc. Only ViG pipes are
capable of performing format conversion, scaling and quality improvement
for source surfaces.
* Layer Mixer (LM):
Blend source surfaces together (in requested zorder)
* PingPong (PP):
This block controls frame done interrupt output, EOL and EOF generation,
overflow/underflow control.
* Display interface (INTF):
Timing generator and interface connecting the display peripherals.
DRM components mapping to DPU architecture:
------------------------------------------
PLANEs maps to SSPPs
CRTC maps to LMs
Encoder maps to PPs, INTFs
Data flow setup:
---------------
MDSS hardware can support various data flows (e.g.):
- Dual pipe: Output from two LMs combined to single display.
- Split display: Output from two LMs connected to two separate
interfaces.
The hardware capabilities determine the number of concurrent data paths
possible. Any control path (i.e. pipeline w/i DPU) can be routed to any
of the hardware data paths. A given control path can be triggered,
flushed and controlled independently.
Changes in v3:
- Move msm_media_info.h from uapi to dpu/ subdir
- Remove preclose callback dpu (it's handled in core)
- Fix kbuild warnings with parent_ops

Add the infrastructure to support the idea of multiple ringbuffers.
Assign each ringbuffer an id and use that as an index for the various
ring specific operations.
The biggest delta is to support legacy fences. Each fence gets its own
sequence number but the legacy functions expect to use a unique integer.
To handle this we return a unique identifier for each submission but
map it to a specific ring/sequence under the covers. Newer users use
a dma_fence pointer anyway so they don't care about the actual sequence
ID or ring.
The actual mechanics for multiple ringbuffers are very target specific
so this code just allows for the possibility but still only defines
one ringbuffer for each target family.

Currently the behavior of a command stream is provided by the user
application during submission and the application is expected to internally
maintain the settings for each 'context' or 'rendering queue' and specify
the correct ones.
This works okay for simple cases but as applications become more
complex we will want to set context specific flags and do various
permission checks to allow certain contexts to enable additional
privileges.
Add kernel-side submit queues to be analogous to 'contexts' or
'rendering queues' on the application side. Each file descriptor
instance will maintain its own list of queues. Queues cannot be
shared between file descriptors.
For backwards compatibility context id '0' is defined as a default
context specifying no priority and no special flags. This is
intended to be the usual configuration for 99% of applications so
that a garden variety application can function correctly without
creating a queue. Only those applications requiring the specific
benefit of different queues need create one.

Previously, in an effort to defer initializing the gpu until firmware
was available (ie. rootfs mounted), the gpu was not loaded at when the
subdevice was bound. Which resulted that clks/etc were requested in a
place that devm couldn't really help unwind if something failed.
Instead move request_firmware() to gpu->hw_init() and construct the gpu
earlier in adreno_bind(). To avoid the rest of the driver needing to
be aware of a gpu that hasn't managed to load firmware and hw_init()
yet, stash the gpu ptr in the adreno device's drvdata, and don't set
priv->gpu() until hw_init() succeeds.

MDSS represents the top level wrapper that contains MDP5, DSI, HDMI and
other sub-blocks. W.r.t device heirarchy, it's the parent of all these
devices. The power domain of this device is actually tied to the GDSC
hw. When any sub-device enables its PD, MDSS's PD is also enabled.
The suspend/resume ops enable the top level clocks that end at the MDSS
boundary. For now, we're letting them all be optional, since the child
devices anyway hold a ref to these clocks.
Until now, we'd called a runtime_get() during probe, which ensured that
the GDSC was always on. Now that we've set up runtime PM for the children
devices, we can get rid of this hack.
Note: that the MDSS device is the platform_device in msm_drv.c. The
msm_runtime_suspend/resume ops call the funcs that enable/disable
the top level MDSS clocks. This is different from MDP4, where the
platform device created in msm_drv.c represents MDP4 itself. It would
have been nicer to hide these differences by adding new kms funcs, but
runtime PM needs to be enabled before kms is set up (i.e, msm_kms_init
is called).
