2019-02-11T09:36:00+00:00

With drmP.h removed from drm_modeset_helper.h the build of
komeda filed as reported by linux-next

Add missing include files to fix build.
For the files touched group include files and sort them.

Merge branch 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld into drm-next

2019-02-01T00:01:50+00:00

This pull includes the new Arm "komeda" DRM driver. It is currently hosted
in the same repo as the other "mali-dp" driver because it is the next
iteration of the IP.

drm: arm/komeda: Remove IRQ parsing from initial series

2019-01-18T10:44:10+00:00

The initial series is only introducing the basic components and not
implementing IRQ handling. Remove the left over code that touches
IRQs until the proper implementation is introduced in a later series.

drm/komeda: Attach komeda_dev to DRM-KMS

2019-01-14T11:20:11+00:00

Add komeda_kms abstracton to attach komeda_dev to DRM-KMS
  CRTC: according to the komeda_pipeline
  PLANE: according to komeda_layer (layer input pipeline)
  PRIVATE_OBJS: komeda_pipeline/component all will be treat as private_objs

komeda_kms is for connecting DRM-KMS and komeda_dev, like reporting the
kms object properties according to the komeda_dev, and pass/convert KMS's
requirement to komeda_dev.

Changes in v4:
- Set drm_atomic_helper_check as mode_config->atomic_check.

Changes in v3:
- Fixed style problem found by checkpatch.pl --strict.

Changes in v2:
- Unified abbreviation of "pipeline" to "pipe".

drm/komeda: Add komeda_format_caps for format handling

2019-01-14T11:09:50+00:00

komeda_format_caps is for describing ARM display specific features and
limitations of a specific format, and format_caps will be linked into
&komeda_framebuffer like a extension of &drm_format_info.
And komed_format_caps_table will be initialized before the enum_resources,
since the layer features description depend on this format_caps table, so
we'd better initialize the table first.

Changes in v4:
- Rebase.

drm/komeda: Build komeda to be a platform module

2019-01-14T11:09:23+00:00

Implement a simple wrapper for platform module to build komeda to module,
Also add a very simple D71 layer code to show how to discover a product.
Komeda driver direct bind the product ENTRY function xxx_identity to DT
compatible name like:

d71_product = {
	.product_id = MALIDP_D71_PRODUCT_ID,
	.identify = d71_identify,
},

const struct of_device_id komeda_of_match[] = {
	{ .compatible = "arm,mali-d71", .data = &d71_product, },
	{},
};

Then when linux found a matched DT node and call driver to probe, we can
easily get the of data, and call into the product to do the identify:

komeda_bind()
{
    ...
    product = of_device_get_match_data(dev);

    product->identify();
    ...
}

Changes in v4:
- Replaced kzalloc with devm_kzalloc

Changes in v3:
