Rename "GEM CMA" helpers to "GEM DMA" helpers - considering the
hierarchy of APIs (mm/cma -> dma -> gem dma) calling them "GEM
DMA" seems to be more applicable.
Besides that, commit e57924d4ae80 ("drm/doc: Task to rename CMA helpers")
requests to rename the CMA helpers and implies that people seem to be
confused about the naming.
In order to do this renaming the following script was used:
```
#!/bin/bash
DIRS="drivers/gpu include/drm Documentation/gpu"
REGEX_SYM_UPPER="[0-9A-Z_\-]"
REGEX_SYM_LOWER="[0-9a-z_\-]"
REGEX_GREP_UPPER="(${REGEX_SYM_UPPER}*)(GEM)_CMA_(${REGEX_SYM_UPPER}*)"
REGEX_GREP_LOWER="(${REGEX_SYM_LOWER}*)(gem)_cma_(${REGEX_SYM_LOWER}*)"
REGEX_SED_UPPER="s/${REGEX_GREP_UPPER}/\1\2_DMA_\3/g"
REGEX_SED_LOWER="s/${REGEX_GREP_LOWER}/\1\2_dma_\3/g"
# Find all upper case 'CMA' symbols and replace them with 'DMA'.
for ff in $(grep -REHl "${REGEX_GREP_UPPER}" $DIRS)
do
sed -i -E "$REGEX_SED_UPPER" $ff
done
# Find all lower case 'cma' symbols and replace them with 'dma'.
for ff in $(grep -REHl "${REGEX_GREP_LOWER}" $DIRS)
do
sed -i -E "$REGEX_SED_LOWER" $ff
done
# Replace all occurrences of 'CMA' / 'cma' in comments and
# documentation files with 'DMA' / 'dma'.
for ff in $(grep -RiHl " cma " $DIRS)
do
sed -i -E "s/ cma / dma /g" $ff
sed -i -E "s/ CMA / DMA /g" $ff
done
# Rename all 'cma_obj's to 'dma_obj'.
for ff in $(grep -RiHl "cma_obj" $DIRS)
do
sed -i -E "s/cma_obj/dma_obj/g" $ff
done
```
Only a few more manual modifications were needed, e.g. reverting the
following modifications in some DRM Kconfig files
- select CMA if HAVE_DMA_CONTIGUOUS
+ select DMA if HAVE_DMA_CONTIGUOUS
as well as manually picking the occurrences of 'CMA'/'cma' in comments and
documentation which relate to "GEM CMA", but not "FB CMA".
Also drivers/gpu/drm/Makefile was fixed up manually after renaming
drm_gem_cma_helper.c to drm_gem_dma_helper.c.
This patch is compile-time tested building a x86_64 kernel with
`make allyesconfig && make drivers/gpu/drm`.

On commit 43531edd53f0 ("drm/sprd: add Unisoc's drm kms master"),
adds the config DRM_SPRD, which selects DRM_KMS_CMA_HELPER.
However, commit 09717af7d13d ("drm: Remove CONFIG_DRM_KMS_CMA_HELPER
option") just removed the DRM_KMS_CMA_HELPER.
So the select DRM_KMS_CMA_HELPER refers to a non-existing kconfig symbol.

Only MIPI DSI Displays supported, DP/TV/HMDI will be support
in the feature.
v1:
- Remove dphy and dsi graph binding, merge the dphy driver into the dsi.
v2:
- Use drm_xxx to replace all DRM_XXX.
- Use kzalloc to replace devm_kzalloc for sprd_dsi structure init.
v4:
- Use drmm_helpers to allocate encoder.
- Move allocate encoder and connector to bind function.
v5:
- Drop the dsi ip file prefix.
- Fix the checkpatch warnings.
- Add Signed-off-by for dsi&dphy patch.
- Use the mode_flags of mipi_dsi_device to setup crtc DPI and EDPI mode.
v6:
- Redesign the way to access the dsi register.
- Reduce the dsi_context member variables.
v7:
- Fix codeing style issue by checkpatch.
- Drop the pll registers structure define.
- Use bridge API instead of drm panel API.
- Register mipi_dsi_host on probe phase;
- Remove some unused function.
v8:
- Fix missing signed-off-by.
- Move component_add to dsi_host.attach callback.

Adds DPU(Display Processor Unit) support for the Unisoc's display
subsystem.
It's support multi planes, scaler, rotation, PQ(Picture Quality) and more.
v2:
- Use drm_xxx to replace all DRM_XXX.
- Use kzalloc to replace devm_kzalloc for sprd_dpu structure init.
v3:
- Remove dpu_layer stuff layer and commit layers by aotmic_update
v4:
- Use drmm_helpers to allocate crtc and planes.
- Move rotation enum definitions to crtc layer reg bitfields.
- Move allocate crtc and planes to bind function.
v5:
- Fix the checkpatch warnings.
- Use mode_set_nofb instead of mode_valid callback.
- Follow the OF-Graph bindings, use of_graph_get_port_by_id
instead of of_parse_phandle.
- Use zpos to represent the layer position.
- Rebase to last drm misc branch.
v6:
- Disable and clear interrupts before register dpu IRQ
- Init dpi config used by crtc_state->adjusted_mode on mode_set_nofb
- Remove enable_irq and disable_irq function call.
- Remove drm_format_info function call.

Adds drm support for the Unisoc's display subsystem.
This is drm kms driver, this driver provides support for the
application framework in Android, Yocto and more.
Application framework can access Unisoc's display internal
peripherals through libdrm or libkms, it's test ok by modetest
(DRM/KMS test tool) and Android HWComposer.
v4:
- Move the devm_drm_dev_alloc to master_ops->bind function.
- The managed drmm_mode_config_init() it is no longer necessary for drivers to explicitly call drm_mode_config_cleanup, so delete it.
v5:
- Remove subdir-ccflgas-y for Makefile.
- Keep the selects sorted by alphabet for Kconfig.
