78f27b1ce3 drm/msm: fix include notation and remove -Iinclude/drm flag
Include <drm/*.h> instead of relative path from include/drm, then
remove the -Iinclude/drm compiler flag.

While we are here, sort the touched parts with public headers first.
mdp4_kms.h must declare struct device_node to be self-contained.

f316b25a23 drm/msm/mdp5: Remove mixer/intf pointers from mdp5_ctl
These are a part of CRTC state, it doesn't feel nice to leave them
hanging in mdp5_ctl struct. Pass mdp5_pipeline pointer instead
wherever it is needed.

We still have some params in mdp5_ctl like start_mask etc which
are derivative of atomic state, and should be rolled back if
a commit fails, but it doesn't seem to cause much trouble.

36d1364abb drm/msm/mdp5: Clean up interface assignment
mdp5_interface struct contains data corresponding to a INTF
instance in MDP5 hardware. This sturct is memcpy'd to the
mdp5_encoder struct, and then later to the mdp5_ctl struct.

Instead of copying around interface data, create mdp5_interface
instances in mdp5_init, like how it's done currently done for
pipes and layer mixers. Pass around the interface pointers to
mdp5_encoder and mdp5_ctl. This simplifies the code, and allows
us to decouple encoders from INTFs in the future if needed.

a2380124fb drm/msm/mdp5: Simplify LM <-> PP mapping
PingPong ID for a Layer Mixer is already contained in
mdp5_hw_mixer.

This avoids the need to retrieve PP ID using macros

adfc0e63ab drm/msm/mdp5: Start using mdp5_hw_mixer
Use the mdp5_hw_mixer struct in the mdp5_crtc and mdp5_ctl instead of
using the LM index.

Like before, the Layer Mixers are assigned statically to the CRTCs.
The hwmixer(s) will later be dynamically assigned to CRTCs.

For now, ignore the hwmixers that can only do WB.

b3a94705a0 drm/msm/mdp5: Create single encoder per interface (INTF)
For the DSI interfaces, the mdp5_kms core creates 2 encoders for video
and command modes.

Create only a single encoder per interface. When creating the encoder, set
the interface type to MDP5_INTF_MODE_NONE. It's the bridge (DSI/HDMI/eDP)
driver's responsibility to set a different interface type. It can use the
the kms func op set_encoder_mode to change the mode of operation, which
in turn would configure the interface type for the INTF.

In mdp5_cmd_encoder.c, we remove the redundant code, and make the commmand
mode funcs as helpers that are used in mdp5_encoder.c

7b59c7e449 drm/msm/mdp5: Use updated MDP5 register names
Since MDSS registers were stuffed within the the MDP5 register
space, we had an __offset_MDP() macro to identify the offset
between the start of MDSS and MDP5 address spaces. This offset
macro expected a MDP index argument, which didn't make much
sense since we don't have multiple MDPs.

The offset is no longer needed now that we have devices for the 2
different register address spaces. Also, remove the "REG_MDP5_MDP_"
prefix to "REG_MDP5_".

Update the generated headers in mdp5.xml.h

We generally update headers as a separate patch, but we need to
do these together to prevent breaking build.

c71716b17b drm/msm/mdp5: Allocate CTL for each display interface
In MDP5, CTL contains information of the whole pipeline whose
output goes down to a display interface. In various cases, one
interface may require 2 CRTCs, but only one CTL. Some interfaces
also require to use certain CTLs.

Instead of allocating CTL for each active CRTC, this change is to
associate a CTL with each interface.

6490ad4740 drm/msm: clarify downstream bus scaling
A few spots in the driver have support for downstream android
CONFIG_MSM_BUS_SCALING.  This is mainly to simplify backporting the
driver for various devices which do not have sufficient upstream
kernel support.  But the intentionally dead code seems to cause
some confusion.  Rename the #define to make this more clear.

and sequence change to support dual data path.
