Subject: [PATCH v4 00/10] drm/verisilicon : support DC8200 and inno hdmi

Verisilicon/DC8200 display controller IP has 2 display pipes and each
pipe support a primary plane and a cursor plane .
In addition, there are four overlay planes as two display pipes common resources.

The first display pipe is bound to the inno HDMI encoder.
The second display pipe is bound to a simple encoder, which is used to
find dsi bridge by dts node.

Patch 1 adds YAML schema for JH7110 display pipeline.

Patches 2 to 3 add inno common api and match the ROCKCHIP inno hdmi driver
by calling the common api.
The collating public interface is based on ROCKCHIP inno hdmi,
and it can be resused by JH7110 inno hdmi.
Those common api are tested on rk-3128 SDK, which kernel version is 4.x.
step1, make sure the process is consistent with the latest kernel version.
step2, just remove the interface and add a common interface.

Patches 4 to 8 add kms driver for dc8200 display controller.

Patch 9 adds inno hdmi support for JH7110 display pipeline.

Patch 10 adds a simple encoder.

This patchset should be applied on next branch.

V1:
Changes since v1:
- Further standardize the yaml file.
- Dts naming convention improved.
- Fix the problem of compiling and loading ko files.
- Use drm new api to automatically manage resources.
- Drop vs_crtc_funcs&vs_plane_funcs, subdivide the plane's help interface.
- Reduce the modifiers unused.
- Optimize the hdmi driver code

V2:
Changes since v2:
- fix the error about checking the yaml file.
- match drm driver GEM DMA API.
- Delete the custom crtc property .
- hdmi use drmm_ new api to automatically manage resources.
- update the modifiers comments.
- enabling KASAN, fix the error during removing module

V3:
Changes since v3:
- Delete the custom plane property.
- Delete the custom fourcc modifiers.
- Adjust the calculation mode of hdmi pixclock.
- Add match data for dc8200 driver.
- Adjust some magic values.
- Add a simple encoder for dsi output.

V4:
Changes since v4:
- Delete the display subsystem module as all crtcs and planes are a driver.
- Delete the custom struct, directly use the drm struct data.
- Tidy up the inno hdmi public interface.
- Add a simple encoder for dsi output.

Please fix your clock, so this patchset does not appear +4h in the

as you were working on the rk3128-inno-hdmi variant recently
and I don't really have a rk3036 or rk3128 in working condition
right now, could you give this series a try.

For reference, the full series is at lore:
https://lore.kernel.org/dri-devel/[email protected]/

and generalizes the inno-hdmi driver into the bridge model we
have in a number of other places already.


Thanks
Heiko

Hm, why freeing? That's a devm. You don't free other pieces in bind paths...

Please do not print simple success messages. Tracing tells you this and
driver should be quiet in typical cases.

You have also some weird tabs instead of spaces here and there... like
before 'encoder' arguments. This is needs some basic style check.

I really don't want to anticipate bridge maintainer's feedback, but new
bridge drivers must not contain connector creation. That must happen
somewhere else.
Also I'm neither seeing any drm_brige struct nor drm_bridge_funcs, which
are both essential for a bridge driver. I don't think moving a part of a
driver to .../drm/bridge/ makes it a bridge driver.

You're absolutely right :-) Connector creation should be handled by the
drm_bridge_connector helper. The HDMI bridge driver should focus on the
HDMI bridge itself.

Could you please settle on a single prefix for all your function names?
Ideally it should be close to the driver name. It's hard to understand
that the function comes from the verisilicon driver if its name starts
from dc_ or especially with plane_.

I'd strongly suggest to stop defining anything outside of the selected
vs_ namespace.

These types are largely unused within this patch. Please drop all the
unused parts and add them later, when required.

static int inno_bridge_attach(struct drm_bridge *bridge,
enum drm_bridge_attach_flags flags)
{
struct inno_hdmi *hdmi = bridge_to_inno(bridge);

if (flags & DRM_BRIDGE_ATTACH_NO_CONNECTOR) {
DRM_ERROR("Fix bridge driver to make connector optional!");
return -EINVAL;
}
hdmi->connector.polled = DRM_CONNECTOR_POLL_HPD;

drm_connector_helper_add(&hdmi->connector,
&inno_hdmi_connector_helper_funcs);

drmm_connector_init(drm, &hdmi->connector,
&inno_hdmi_connector_funcs,
DRM_MODE_CONNECTOR_HDMIA,
hdmi->ddc);

drm_connector_attach_encoder(&hdmi->connector, encoder);
}

static const struct drm_bridge_funcs inno_bridge_attach = {
.attach = inno_bridge_attach,
};

Connector creation is handled by the drm_bridge_funcs ->attach.
Is it ok?

It's kind of a general comment, but I don't think that's the right
abstraction. You should create a inno_hdmi bridge that allows to
supplement some of the atomic hooks, but not reimplement them entirely
each time.

You can have a look at how dw-hdmi does it for example. Also, why do you
still need the encoder and connectors?

This kind of code was added to existing bridge drivers when we
transitioned to the new model where bridges don't create the connectors,
because we couldn't fix all the existing bridges in one go. New bridges
must do the opposite. See imx8qxp-pixel-link.c for instance, it has this
code instead in its attach function:

if (!(flags & DRM_BRIDGE_ATTACH_NO_CONNECTOR)) {
DRM_DEV_ERROR(pl->dev,
"do not support creating a drm_connector\n");
return -EINVAL;
}

(I would personally drop the DRM_DEV_ERROR message)

No, the connector should be created by the display controller driver by
calling drm_brige_connector_init(). It should not be created by the
bridge driver. The bridge driver should provide the bridge functions
(drm_bridge_funcs), but not create any connector.
