[PATCH v4 00/41] drm: renesas: shmobile: Atomic conversion + DT support

[PATCH v4 00/41] drm: renesas: shmobile: Atomic conversion + DT support

[Geert Uytterhoeven]

	Hi all,

It has been 3 years since the last conversion of a DRM driver to atomic
modesetting, so I guess it's time for another one? ;-)

Currently, there are two drivers for the LCD controller on Renesas
SuperH-based and ARM-based SH-Mobile and R-Mobile SoCs:
  1. sh_mobile_lcdcfb, using the fbdev framework,
  2. shmob_drm, using the DRM framework.
However, only the former driver is used, as all platform support
integrates the former.  None of these drivers support DT-based systems.

This patch series converts the SH-Mobile DRM driver to atomic
modesetting, and adds DT support, complemented by the customary set of
fixes and improvements.

Overview:
  - Patch 1 adds a separate maintainer entry.
  - Patch 2 adds DT bindings for the SH-Mobile LCD controller,
  - Patch 3 adds definitions for RGB666 9:9 media bus formats,
  - Patches 4-35 contains miscellaneous fixes, improvements, and
    cleanups for the SH-Mobile DRM driver,
  - Patches 36-40 convert the SH-Mobile DRM driver to atomic
    modesetting,
  - Patch 41 adds DT support to the SH-Mobile DRM driver.

To reduce strain on the audience, I have CCed the DT and media people
only on the cover letter and the DT resp. media patches.  If interested,
the full series should be available through lore.kernel.org.

Some comments and questions can be found in the individual patches.

Changes compared to v3[1]:
  - Rebase on top of v6.6-rc1 and commit 775b0669e19f2e4a
    ("drm/shmobile: Convert to platform remove callback returning void")
    in drm-misc/for-linux-next.

Changes compared to v2[2]:
  - Add Reviewed-by.

Changes compared to v1[3]:
  - New patches:
      - "[PATCH v2 01/41] MAINTAINER: Create entry for Renesas SH-Mobile
	 DRM drivers",
      - "[PATCH v2 18/41] drm: renesas: shmobile: Remove custom plane
	 destroy callback",
  - Add myself as co-maintainer,
  - Make fck clock required,
  - Drop ports description referring to obsolete graph.txt,
  - Condition ports to compatible strings,
  - Drop label and status from example,
  - Add Reviewed-by,
  - Drop unused MEDIA_BUS_FMT_RGB666_2X9_LE, as requested by Laurent,
  - Move explicit clock handling to Runtime PM callbacks,
  - Move devm_pm_runtime_enable() after shmob_drm_setup_clocks(),
  - Depend on PM,
  - Split off removal of call to drm_plane_force_disable(),
  - Select VIDEOMODE_HELPERS,
  - Keep table instead of replacing it by a switch() statement,
  - Fix shmob_drm_interface_data.bus_fmt comment,
  - Drop superfluous blank lines,
  - Keep initialization of info fields together,
  - Use shmob_drm_bus_fmts[],
  - Keep bus format validation at probe time,
  - Pass plane type to shmob_drm_plane_create() to avoid having to shift
    all overlay plane indices by one,
  - Rename primary_plane_funcs to shmob_drm_primary_plane_funcs,
  - Rename shmob_drm_plane_funcs to shmob_drm_overlay_plane_funcs,
  - Move shmob_drm_crtc_finish_page_flip() further up,
  - Inline shmob_drm_crtc_st{art,op}(),
  - Use devm_drm_of_get_bridge(),
  - Don't print bridge->of_node on failure, as this field depends on
    CONFIG_OF.

This has been tested on the R-Mobile A1-based Atmark Techno
Armadillo-800-EVA development board, using both legacy[4] and
DT-based[5] instantiation, with the fbdev-emulated text console, fbset,
and modetest, a.o.

    modetest -M shmob-drm -s 43:800x480@RG16 -P 33@41:640x320+80+80@RG16
    modetest -M shmob-drm -s 43:800x480@RG16

The output of "modetest -M shmob-drm" can be found below[6].

Not much activity has happened since v2, how can we move this forward?
Thanks!

[PATCH v4 02/41] dt-bindings: display: Add Renesas SH-Mobile LCDC bindings

[Geert Uytterhoeven]

Add device tree bindings for the LCD Controller (LCDC) found in Renesas
SuperH SH-Mobile and ARM SH/R-Mobile SOCs.

Based on a plain text prototype by Laurent Pinchart.

v4:
  - No changes,

v3:
  - Add Reviewed-by,

v2:
  - Add myself as co-maintainer,

[GIT PULL] drm: renesas: shmobile: Atomic conversion + DT support (was: Re: [PATCH v4 00/41] drm: renesas: shmobile: Atomic conversion + DT support)

[Geert Uytterhoeven]

Hi David, Daniel,

The following changes since commit 0663e1da5ba8e6459e3555ac12c62741668c0d30:

  drm/dp_mst: Tune down error message during payload addition
(2023-09-18 16:38:21 +0300)

  drm: renesas: shmobile: Add DT support (2023-09-19 15:58:04 +0200)

----------------------------------------------------------------
drm: renesas: shmobile: Atomic conversion + DT support

Currently, there are two drivers for the LCD controller on Renesas
SuperH-based and ARM-based SH-Mobile and R-Mobile SoCs:
  1. sh_mobile_lcdcfb, using the fbdev framework,
  2. shmob_drm, using the DRM framework.
However, only the former driver is used, as all platform support
integrates the former.  None of these drivers support DT-based systems.

Convert the SH-Mobile DRM driver to atomic modesetting, and add DT
support, complemented by the customary set of fixes and improvements.

Link: https://lore.kernel.org/r/cover.1694767208.git.geert+renesas@glider.be/

This PR is based on today's drm-misc/for-linux-next, to avoid a
conflict with commit 775b0669e19f2e4a ("drm/shmobile: Convert to
platform remove callback returning void") in drm-misc/for-linux-next
.
Thanks for pulling!

I'm technically listed as the maintainer for this driver until Geert
takes over, so for this pull request,

Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

And after that, shmobile won't need my ack to merge further changes :-)

This is very nice work Geert. I'm looking forward to dropping the
sh_mobile_lcdcfb driver.

Now drm-misc/for-linux-next (which is still at v6.5-rc2) has been
merged into drm/drm-next (which is at v6.6-rc2), do you want me to
rebase my branch to current drm/drm-next, or any other commit?

Thanks!

[GIT PULL v2] drm: renesas: shmobile: Atomic conversion + DT support (was: Re: [PATCH v4 00/41] drm: renesas: shmobile: Atomic conversion + DT support)

[Geert Uytterhoeven]

        Hi David, Daniel,

The following changes since commit 389af786f92ecdff35883551d54bf4e507ffcccb:

  Merge tag 'drm-intel-next-2023-09-29' of
git://anongit.freedesktop.org/drm/drm-intel into drm-next (2023-10-04
13:55:19 +1000)

are available in the Git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git

  drm: renesas: shmobile: Add DT support (2023-10-16 11:47:48 +0200)

----------------------------------------------------------------
drm: renesas: shmobile: Atomic conversion + DT support

Currently, there are two drivers for the LCD controller on Renesas
SuperH-based and ARM-based SH-Mobile and R-Mobile SoCs:
  1. sh_mobile_lcdcfb, using the fbdev framework,
  2. shmob_drm, using the DRM framework.
However, only the former driver is used, as all platform support
integrates the former.  None of these drivers support DT-based systems.

Convert the SH-Mobile DRM driver to atomic modesetting, and add DT
support, complemented by the customary set of fixes and improvements.

Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Link: https://lore.kernel.org/r/cover.1694767208.git.geert+renesas@glider.be/

Changes compared to v1:
  - Rebase to drm-next,
  - Add Acked-by.

Thanks for pulling!

Please note that this is a hard dependency for adding shmobile-lcdc
device nodes to DTS files, which is in turn a hard dependency for
removing drivers/staging/board/, and for removing legacy clkdev
registration from various clock drivers.

Thanks for pulling!
