[PATCH v3 00/41] drm: renesas: shmobile: Atomic conversion + DT support

[PATCH v3 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 v2[1]:
  - Add Reviewed-by.

Changes compared to v1[2]:
  - 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[3] and
DT-based[4] instantiation, with the fbdev-emulated text console 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[5].

[PATCH v3 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.

  - 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[3] and
DT-based[4] instantiation, with the fbdev-emulated text console 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[5].

[PATCH v3 04/41] drm: renesas: shmobile: Fix overlay plane disable

[Geert Uytterhoeven]

Merely writing zero to the CHn Source Image Format Register is not
sufficient to disable a plane, as the programmed register value is not
propagated immediately to the current side.  This can be seen when using
the -P option of modetest: the extra plane is displayed correctly, but
does not disappear after exit.

Fix this by doing the full update dance using the Blend Control
Register, like is done when enabling the plane.

[PATCH v3 05/41] drm: renesas: shmobile: Fix ARGB32 overlay format typo

[Geert Uytterhoeven]

When configuring a CHn Source Image Format Register (LDBBSIFR), one
should use the corresponding LDBBSIFR_RPKF_* definition for overlay
planes, not the DDFR_PKF_* definition for the primary plane.

Fortunately both definitions resolve to the same value, so this bug did
not cause any harm.

[PATCH v3 06/41] drm: renesas: shmobile: Correct encoder/connector types

[Geert Uytterhoeven]

The first encoder output on the SH-Mobile LCD Controller is a DPI
parallel bus.  However, at the time of introduction of the driver, no
encoder or connector types were defined yet for the DPI parallel bus,
hence the driver used the ones for LVDS instead.

Adjust the types accordingly.

[PATCH v3 07/41] drm: renesas: shmobile: Add support for Runtime PM

[Geert Uytterhoeven]

The SH-Mobile LCD Controller is part of a PM Domain on all relevant SoCs
(clock domain on all, power domain on some).  Hence it may not be
sufficient to manage the LCDC module clock explicitly (e.g. if the
selected clock source differs from SHMOB_DRM_CLK_BUS).

Fix this by using Runtime PM for all clock handling.  Add an explicit
dependency on CONFIG_PM, which should already be met on all affected
platforms.

[PATCH v3 10/41] drm: renesas: shmobile: Add missing YCbCr formats

[Geert Uytterhoeven]

The primary plane supports various YCbCr formats, and the CRTC code
already knows how to handle them.  Enable support for the missing
formats by adding them to the table of supported modes.

[PATCH v3 12/41] drm: renesas: shmobile: Remove backlight support

[Geert Uytterhoeven]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

Backlight support should be implemented by panels, not by the LCDC
driver.  As the feature is currently unused anyway, remove it.

Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
[geert: Cleanups]
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
Reviewed-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

v3:
  - No changes,

v2:
  - Add Reviewed-by.

Changes compared to Laurent's original:
  - Rebase,
  - Remove unused variable ‘scon’,
  - Remove now unused to_shmob_encoder() macro,
  - Remove now empty shmob_drm_encoder wrapper.

[PATCH v3 12/41] drm: renesas: shmobile: Remove backlight support

[Geert Uytterhoeven]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

Backlight support should be implemented by panels, not by the LCDC
driver.  As the feature is currently unused anyway, remove it.

v3:
  - No changes,

v2:
  - Add Reviewed-by.

Changes compared to Laurent's original:
  - Rebase,
  - Remove unused variable ‘scon’,
  - Remove now unused to_shmob_encoder() macro,
  - Remove now empty shmob_drm_encoder wrapper.

[PATCH v3 14/41] drm: renesas: shmobile: Rename input clocks

[Geert Uytterhoeven]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

Prepare for DT bindings by using more appropriate names for the input
clocks.

Note that all LDDCKR_ICKSEL_* definitions but the one for the bus clock
are valid only for SH7724, so the clock selection code needs to be
updated when extending clock support to other SoCs.

[PATCH v3 14/41] drm: renesas: shmobile: Rename input clocks

[Geert Uytterhoeven]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

Prepare for DT bindings by using more appropriate names for the input
clocks.

Note that all LDDCKR_ICKSEL_* definitions but the one for the bus clock
are valid only for SH7724, so the clock selection code needs to be
updated when extending clock support to other SoCs.

SYS panels are not used, and have no defined DT bindings.  Remove their

[PATCH v3 18/41] drm: renesas: shmobile: Remove custom plane destroy callback

[Geert Uytterhoeven]

There is no need to call drm_plane_force_disable() from the plane's
.destroy() callback, as the plane should have been disabled already
before.  See also commit 3c858a33858baa8c ("drm/plane_helper: don't
disable plane in destroy function") for the generic plane helper case.

After removing this call, shmob_drm_plane_destroy() becomes a simple
wrapper around shmob_drm_plane_destroy(), hence replace it by the
latter.

[PATCH v3 20/41] drm: renesas: shmobile: Embed drm_device in shmob_drm_device

[Geert Uytterhoeven]

Embedding drm_device in shmob_drm_device allows us to use the DRM
managed API to allocate both structures in one go, simplifying error
handling.

[PATCH v3 22/41] drm: renesas: shmobile: Replace .dev_private with container_of()

[Geert Uytterhoeven]

Now that drm_device is embedded in shmob_drm_device, we can use
a container_of()-based helper to get the shmob_drm_device pointer from
the drm_device, instead of using the deprecated drm_device.dev_private
field.

While at it, restore reverse Xmas tree ordering of local variable
declarations.

[PATCH v3 22/41] drm: renesas: shmobile: Replace .dev_private with container_of()

[Geert Uytterhoeven]

Now that drm_device is embedded in shmob_drm_device, we can use
a container_of()-based helper to get the shmob_drm_device pointer from
the drm_device, instead of using the deprecated drm_device.dev_private
field.

While at it, restore reverse Xmas tree ordering of local variable
declarations.

[PATCH v3 23/41] drm: renesas: shmobile: Use struct videomode in platform data

[Geert Uytterhoeven]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

Replace the drm_mode_modeinfo field with videomode that includes more
signal polarity flags.  This simplifies driver handling of panel modes
and prepares for DT support.

[PATCH v3 23/41] drm: renesas: shmobile: Use struct videomode in platform data

[Geert Uytterhoeven]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

Replace the drm_mode_modeinfo field with videomode that includes more
signal polarity flags.  This simplifies driver handling of panel modes
and prepares for DT support.

v3:
  - No changes,

v2:
  - Add Reviewed-by,
  - Select VIDEOMODE_HELPERS.

Changes compared to Laurent's original:
  - Rebase,
  - Fix build,
  - Remove unneeded {width,height}_mm intermediaries from
    shmob_drm_connector,
  - Replace embedded videomode by a const pointer to pdata.

[PATCH v3 26/41] drm: renesas: shmobile: Unify plane allocation

[Geert Uytterhoeven]

Unify primary and overlay plane allocation:
  - Enhance shmob_drm_plane_create() so it can be used to create the
    primary plane, too,
  - Move overlay plane creation next to primary plane creation.

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

v3:
  - No changes,

v2:
  - 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.

[PATCH v3 33/41] drm: renesas: shmobile: Turn vblank on/off when enabling/disabling CRTC

[Geert Uytterhoeven]

The DRM core vblank handling mechanism requires drivers to forcefully
turn vblank reporting off when disabling the CRTC, and to restore the
vblank reporting status when enabling the CRTC.
Implement this using the drm_crtc_vblank_{on,off}() helpers.

Note that drm_crtc_vblank_off() must be called at startup to synchronize
the state of the vblank core code with the hardware, which is initially
disabled.  This is performed at CRTC creation time, requiring vertical
blank initialization to be moved before creating CRTCs.

[PATCH v3 36/41] drm: renesas: shmobile: Atomic conversion part 1

[Geert Uytterhoeven]

Implement atomic mode setting for both the primary and overlay planes.
This involves:
  - Moving the primary plane handling code from CRTC mode setting to
    plane handling shared by primary and overlay planes,
  - Adding basic CRTC and mode config atomic mode setting ops, which
    don't do much yet.

[PATCH v3 36/41] drm: renesas: shmobile: Atomic conversion part 1

[Geert Uytterhoeven]

Implement atomic mode setting for both the primary and overlay planes.
This involves:
  - Moving the primary plane handling code from CRTC mode setting to
    plane handling shared by primary and overlay planes,
  - Adding basic CRTC and mode config atomic mode setting ops, which
    don't do much yet.

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

[PATCH v3 37/41] drm: renesas: shmobile: Atomic conversion part 2

[Geert Uytterhoeven]

Implement atomic mode setting for the CRTC, using the existing dpms
callback.

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
---
This works, but I had expected that crtc_helper_funcs.atomic_check
should point to drm_crtc_helper_atomic_check() instead, as the primary

This works, but I had expected that crtc_helper_funcs.atomic_check
should point to drm_crtc_helper_atomic_check() instead, as the primary
plane cannot be disabled.  However in doing so, when
drm_atomic_helper_check_crtc_primary_plane() fails:

    [drm:drm_atomic_helper_check_crtc_primary_plane] [CRTC:41:crtc-0] primary plane missing

v2:
  - Use devm_drm_of_get_bridge(),
  - Don't print bridge->of_node on failure, as this field depends on
    CONFIG_OF.

Notes:
  - SH-Mobile AG5 (SH73A0) support is untested.
  - Unbind crashes when drm_encoder_cleanup() calls drm_bridge_detach(),
    as the bridge (allocated by devm_drm_panel_bridge_add()) has already
    been freed by that time. This is a known issue with the bridge code.
