drm/sun4i: Run DRM default client setup

2024-09-26T07:31:27+00:00

Call drm_client_setup() to run the kernel's default client setup
for DRM. Set fbdev_probe in struct drm_driver, so that the client
setup can start the common fbdev client.

The sun4i driver specifies as preferred color mode of 32. As this
is the default if no format has been given, leave it out entirely.

v5:
- select DRM_CLIENT_SELECTION

drm/sun4i: hdmi: Switch to HDMI connector

2024-05-28T08:24:43+00:00

The new HDMI connector infrastructure allows to remove some boilerplate,
especially to generate infoframes. Let's switch to it.

drm/gem: rename GEM CMA helpers to GEM DMA helpers

2022-08-03T16:31:49+00:00

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`.

drm/sun4i: Update Kconfig defaults and descriptions

2022-07-08T11:41:19+00:00

Allwinner display drivers are split roughly into two generations. The
first generation was found on early 32-bit ARM SoCs and contains DE1.0
and a custom HDMI controller. Clarify that these options only apply to
a specific list of SoCs, and limit selecting them to 32-bit ARM, to
avoid confusion.

The second generation, found in A83T and newer SoCs (both 32-bit and
64-bit), contains a DE2.0 and a DesignWare HDMI controller. Since this
is the most widely-used generation, enable it by default. The previous
default condition (MACH_SUN8I) was limited to 32-bit SoCs. Also enable
the DSI controller by default, which is found on 64-bit SoCs as well.

drm/sun4i: Allow building the driver on RISC-V

2022-04-26T12:24:04+00:00

Allwinner D1 is a RISC-V SoC which contains a DE 2.0 engine. Let's
remove the dependency on a specific CPU architecture, so the driver can
be built wherever ARCH_SUNXI is selected.

drm: Remove CONFIG_DRM_KMS_CMA_HELPER option

2021-11-30T10:10:03+00:00

Link drm_fb_cma_helper.o into drm_cma_helper.ko if CONFIG_DRM_KMS_HELPER
has been set. Remove CONFIG_DRM_KMS_CMA_HELPER config option. Selecting
KMS helpers and CMA will now automatically enable CMA KMS helpers.

Some drivers' Kconfig files did not correctly select KMS or CMA helpers.
Fix this as part of the change.

drm/sun4i: fix unmet dependency on RESET_CONTROLLER for PHY_SUN6I_MIPI_DPHY

2021-11-15T09:52:03+00:00

When PHY_SUN6I_MIPI_DPHY is selected, and RESET_CONTROLLER
is not selected, Kbuild gives the following warning:

WARNING: unmet direct dependencies detected for PHY_SUN6I_MIPI_DPHY
  Depends on [n]: (ARCH_SUNXI [=n] || COMPILE_TEST [=y]) && HAS_IOMEM [=y] && COMMON_CLK [=y] && RESET_CONTROLLER [=n]
  Selected by [y]:
  - DRM_SUN6I_DSI [=y] && HAS_IOMEM [=y] && DRM_SUN4I [=y]

This is because DRM_SUN6I_DSI selects PHY_SUN6I_MIPI_DPHY
without selecting or depending on RESET_CONTROLLER, despite
PHY_SUN6I_MIPI_DPHY depending on RESET_CONTROLLER.

These unmet dependency bugs were detected by Kismet,
a static analysis tool for Kconfig. Please advise if this
is not the appropriate solution.

v2:
Fixed indentation to match the rest of the file.
