drm: prefix header search paths with $(srctree)/

2019-05-31T13:43:22+00:00

[ Upstream commit 43068cb7ba1f6ceb1523e947c84002b2a61fd6d4 ] Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks. Having whitespaces after -I does not matter since commit 48f6e3cf5bc6 ("kbuild: do not drop -I without parameter").

drm/komeda: fix build with drm_modeset_helper.h update

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. The fix was tested on a tree with drm-misc-next merged. And the patch was also tested to work without drm-misc-next merged. Build tested on arm + x86.

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

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.

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: - Fixed style problem found by checkpatch.pl --strict.
