Add a driver that will work with most MIPI DBI compatible SPI panels.
This avoids adding a driver for every new MIPI DBI compatible controller
that is to be used by Linux. The 'compatible' Device Tree property with
a '.bin' suffix will be used to load a firmware file that contains the
controller configuration.
Example (driver will load sainsmart18.bin):
display@0 {
compatible = "sainsmart18", "panel-mipi-dbi-spi";
...
};
v5:
- kconfig: s/DRM_KMS_CMA_HELPER/DRM_GEM_CMA_HELPER/ (Sam)
- kconfig: Add select VIDEOMODE_HELPERS (Sam)
- kconfig: Add wiki url in the description (Sam)
- Split out and use of_get_drm_panel_display_mode()(Sam)
- Only use the first compatible to look for a firmware file since the
binding mandates 2 compatibles.
- Make having a firmware file mandatory so we can print an error
message if it's missing to improve the user experience. It's very
unlikely that a controller doesn't need to be initialized and if
it doesn't, it's possible to have a firmware file containing only
a DCS NOP.
v4:
- Move driver to drm/tiny where the other drivers of its kind are located.
The driver module will not be shared with a future DPI driver after all.
v3:
- Move properties to DT (Maxime)
- The MIPI DPI spec has optional support for DPI where the controller is
configured over DBI. Rework the command functions so they can be moved
to drm_mipi_dbi and shared with a future panel-mipi-dpi-spi driver
v2:
- Drop model property and use compatible instead (Rob)
- Add wiki entry in MAINTAINERS

This is a KMS driver for emulated cirrus device in qemu.
|
|
It is *NOT* intended for real cirrus devices. This requires
|
|
the modesetting userspace X.org driver.
|
|
|
|
Cirrus is obsolete, the hardware was designed in the 90ies
|
|
and can't keep up with todays needs. More background:

Better alternatives are:
|
|
- stdvga (DRM_BOCHS, qemu -vga std, default in qemu 2.2+)
|
|
- qxl (DRM_QXL, qemu -vga qxl, works best with spice)
|

- virtio (DRM_VIRTIO_GPU), qemu -vga virtio)

DRM driver for simple platform-provided framebuffers.

This driver assumes that the display hardware has been initialized
|
|
by the firmware or bootloader before the kernel boots. Scanout
|
|
buffer, size, and display format must be provided via device tree,
|
|
UEFI, VESA, etc.
|
|

|
On x86 BIOS or UEFI systems, you should also select SYSFB_SIMPLEFB
|
|
to use UEFI and VESA framebuffers.
