Synopsys DesignWare MIPI DSI host controller
============================================
This document defines device tree properties for the Synopsys DesignWare MIPI
DSI host controller. It doesn't constitue a device tree binding specification
by itself but is meant to be referenced by platform-specific device tree
bindings.
When referenced from platform device tree bindings the properties defined in
this document are defined as follows. The platform device tree bindings are
responsible for defining whether each optional property is used or not.
- reg: Memory mapped base address and length of the DesignWare MIPI DSI
host controller registers. (mandatory)
- clocks: References to all the clocks specified in the clock-names property
as specified in [1]. (mandatory)
- clock-names:
- "pclk" is the peripheral clock for either AHB and APB. (mandatory)
- "px_clk" is the pixel clock for the DPI/RGB input. (optional)
- resets: References to all the resets specified in the reset-names property
as specified in [2]. (optional)
- reset-names: string reset name, must be "apb" if used. (optional)
- panel or bridge node: see [3]. (mandatory)

description: |
The IT6505 is a high-performance DisplayPort 1.1a transmitter,
fully compliant with DisplayPort 1.1a, HDCP 1.3 specifications.
The IT6505 supports color depth of up to 36 bits (12 bits/color)
and ensures robust transmission of high-quality uncompressed video
content, along with uncompressed and compressed digital audio content.
Aside from the various video output formats supported, the IT6505
also encodes and transmits up to 8 channels of I2S digital audio,
with sampling rate up to 192kHz and sample size up to 24 bits.
In addition, an S/PDIF input port takes in compressed audio of up to
192kHz frame rate.
Each IT6505 chip comes preprogrammed with an unique HDCP key,
in compliance with the HDCP 1.3 standard so as to provide secure
transmission of high-definition content. Users of the IT6505 need not
purchase any HDCP keys or ROMs.

Remove drm_display_mode.hsync
-----------------------------
We have drm_mode_hsync() to calculate this from hsync_start/end, since drivers
shouldn't/don't use this, remove this member to avoid any temptations to use it
in the future. If there is any debug code using drm_display_mode.hsync, convert
it to use drm_mode_hsync() instead.

select DRM_GEM_SHMEM_HELPER
help
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:
https://www.kraxel.org/blog/2014/10/qemu-using-cirrus-considered-harmful/
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)
