Paul Cercueil 90b86fcc47 DRM: Add KMS driver for the Ingenic JZ47xx SoCs 
Add a KMS driver for the Ingenic JZ47xx family of SoCs.
This driver is meant to replace the aging jz4740-fb driver.

This driver does not make use of the simple pipe helper, for the reason
that it will soon be updated to support more advanced features like
multiple planes, IPU integration for colorspace conversion and up/down
scaling, support for DSI displays, and TV-out and HDMI outputs.

Notes:
    v2: - Remove custom handling of panel. The panel is now discovered using
          the standard API.
        - Lots of small tweaks suggested by upstream

    v3: - Use devm_drm_dev_init()
        - Update compatible strings to -lcd instead of -drm
        - Add destroy() callbacks to plane and crtc
        - The ingenic,lcd-mode is now read from the bridge's DT node

    v4: Remove ingenic,lcd-mode property completely. The various modes are now
        deduced from the connector type, the pixel format or the bus flags.

    v5: - Fix framebuffer size incorrectly calculated for 24bpp framebuffers
        - Use 32bpp framebuffer instead of 16bpp, as it'll work with both
          16-bit and 24-bit panel
        - Get rid of drm_format_plane_cpp() which has been dropped upstream
        - Avoid using drm_format_info->depth, which is deprecated.

help
In order to keep user-space compatibility, we want in certain
use-cases to keep leaking the fbdev physical address to the
user-space program handling the fbdev buffer.
This affects, not only, Amlogic, Allwinner or Rockchip devices
with ARM Mali GPUs using an userspace Blob.
This option is not supported by upstream developers and should be
removed as soon as possible and be considered as a broken and
legacy behaviour from a modern fbdev device driver.
Please send any bug reports when using this to your proprietary
software vendor that requires this.
If in doubt, say "N" or spread the word to your closed source
library vendor.

Say Y here, if you want to use EDID data to be loaded from the
/lib/firmware directory or one of the provided built-in
data sets. This may be necessary, if the graphics adapter or
monitor are unable to provide appropriate EDID data. Since this
feature is provided as a workaround for broken hardware, the
default case is N. Details and instructions how to build your own
EDID data are given in Documentation/EDID/HOWTO.txt.

Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
APIs to user-space, which can be used to circumvent access
restrictions and other security measures. For backwards compatibility
those drivers are still available, but their use is highly
inadvisable and might harm your system.
You are recommended to use the safe modeset-only drivers instead, and
perform 3D emulation in user-space.
Unless you have strong reasons to go rogue, say "N".
