Now that bridges can expose the bus format/flags they expect, we can use those instead of the relying on the display_info provided by the connector (which is only valid if the encoder is directly connected to bridge element driving the panel/display). We also explicitly expose the bus formats supported by our encoder by filling encoder->output_bus_caps with proper info. v10: * Add changelog to the commit message * Use kmalloc() instead of kcalloc() * Add a dev_warn() when unsupported flags are requested v8 -> v9: * No changes v7: * Add an imx_pd_format_supported() helper (suggested by Philipp) * Simplify imx_pd_bridge_atomic_get_output_bus_fmts() (suggested by Philipp) * Simplify imx_pd_bridge_atomic_get_input_bus_fmts() * Explicitly set the duplicate/destro_state() and reset() hooks v4 -> v6: * Patch was not part of the series v3 (all suggested by Philipp): * Adjust to match core changes * Propagate output format to input format * Pick a default value when output_fmt = _FIXED * Add missing BGR888 and GBR888 fmts to imx_pd_bus_fmts[] v2: * Adjust things to match the new bus-format negotiation infra Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Philipp Zabel <p.zabel@pengutronix.de> Link: https://patchwork.freedesktop.org/patch/msgid/20200128135514.108171-8-boris.brezillon@collabora.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.
