Support the CRTC's color-management property and implement each model's palette support. The OF hardware has different methods of setting the palette. The respective code has been taken from fbdev's offb and refactored into per-model device functions. The device functions integrate this functionality into the overall modesetting. As palette handling is a CRTC property that depends on the primary plane's color format, the plane's atomic_check helper now updates the format field in ofdrm's custom CRTC state. The CRTC's atomic_flush helper updates the palette for the format as needed. v4: * use cpu_to_be32() (Geert) v3: * lookup CRTC state with drm_atomic_get_new_crtc_state() * access HW palette with writeb(), writel(), and readl() (Ben) * declare register values as u32 Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221011150712.3928-5-tzimmermann@suse.de |

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.
