Komeda driver uses a individual component to describe the HW's writeback caps, but drivers doesn't define a new structure and still uses the existing "struct komeda_layer" to describe this new component. The detailed changes as follow: 1. Initialize wb_layer according to HW and report it to CORE. 2. CORE exposes wb_layer as a resource to KMS by private_obj. 3. Report writeback supporting by add a wb_connector to KMS, and then wb_connector will take act as a component resources user, so the func komeda_wb_encoder_atomic_check claims komeda resources (scaler and wb_layer) accroding to its state configuration to the wb_connector. and the wb_state configuration will be validated on the specific component resources to see if the caps of component can meet the requirement of wb_connector. if not check failed. 4. Update irq_handler to notify the completion of writeback. NOTE: This change doesn't add scaling writeback support, that support will be added in the future after the scaler support. v2: Rebase v3: Rebase and constify the d71_wb_layer_funcs v4: Addressed Ayan's comments Depends on: - https://patchwork.freedesktop.org/series/59915/ Signed-off-by: James Qian Wang (Arm Technology China) <james.qian.wang@arm.com> Acked-by: Ayan Kumar Halder <ayan.halder@arm.com> Signed-off-by: Liviu Dudau <liviu.dudau@arm.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
