Merge tag 'drm-next-2019-09-18' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "This is the main pull request for 5.4-rc1 merge window. I don't think
  there is anything outstanding so next week should just be fixes, but
  we'll see if I missed anything. I landed some fixes earlier in the
  week but got delayed writing summary and sending it out, due to a mix
  of sick kid and jetlag!

  There are some fixes pending, but I'd rather get the main merge out of
  the way instead of delaying it longer.

  It's also pretty large in commit count and new amd header file size.
  The largest thing is four new amdgpu products (navi12/14, arcturus and
  renoir APU support).

  Otherwise it's pretty much lots of work across the board, i915 has
  started landing tigerlake support, lots of icelake fixes and lots of
  locking reworking for future gpu support, lots of header file rework

Amlogic specific extensions to the Synopsys Designware HDMI Controller
======================================================================
The Amlogic Meson Synopsys Designware Integration is composed of :
- A Synopsys DesignWare HDMI Controller IP
- A TOP control block controlling the Clocks and PHY
- A custom HDMI PHY in order to convert video to TMDS signal
___________________________________
| HDMI TOP |<= HPD
|___________________________________|
| | |
| Synopsys HDMI | HDMI PHY |=> TMDS
| Controller |________________|
|___________________________________|<=> DDC
The HDMI TOP block only supports HPD sensing.
The Synopsys HDMI Controller interrupt is routed through the
TOP Block interrupt.
Communication to the TOP Block and the Synopsys HDMI Controller is done
via a pair of dedicated addr+read/write registers.
The HDMI PHY is configured by registers in the HHI register block.
Pixel data arrives in 4:4:4 format from the VENC block and the VPU HDMI mux
selects either the ENCI encoder for the 576i or 480i formats or the ENCP
encoder for all the other formats including interlaced HD formats.
The VENC uses a DVI encoder on top of the ENCI or ENCP encoders to generate
DVI timings for the HDMI controller.
Amlogic Meson GXBB, GXL and GXM SoCs families embeds the Synopsys DesignWare
HDMI TX IP version 2.01a with HDCP and I2C & S/PDIF
audio source interfaces.
Required properties:
- compatible: value should be different for each SoC family as :
- GXBB (S905) : "amlogic,meson-gxbb-dw-hdmi"
- GXL (S905X, S905D) : "amlogic,meson-gxl-dw-hdmi"
- GXM (S912) : "amlogic,meson-gxm-dw-hdmi"
followed by the common "amlogic,meson-gx-dw-hdmi"
- G12A (S905X2, S905Y2, S905D2) : "amlogic,meson-g12a-dw-hdmi"
- reg: Physical base address and length of the controller's registers.
- interrupts: The HDMI interrupt number
- clocks, clock-names : must have the phandles to the HDMI iahb and isfr clocks,
and the Amlogic Meson venci clocks as described in
Documentation/devicetree/bindings/clock/clock-bindings.txt,
the clocks are soc specific, the clock-names should be "iahb", "isfr", "venci"
- resets, resets-names: must have the phandles to the HDMI apb, glue and phy
resets as described in :
Documentation/devicetree/bindings/reset/reset.txt,
the reset-names should be "hdmitx_apb", "hdmitx", "hdmitx_phy"
Optional properties:
- hdmi-supply: Optional phandle to an external 5V regulator to power the HDMI
logic, as described in the file ../regulator/regulator.txt
Required nodes:
The connections to the HDMI ports are modeled using the OF graph
bindings specified in Documentation/devicetree/bindings/graph.txt.
The following table lists for each supported model the port number
corresponding to each HDMI output and input.
Port 0 Port 1

Amlogic Meson Display Controller
================================
The Amlogic Meson Display controller is composed of several components
that are going to be documented below:
DMC|---------------VPU (Video Processing Unit)----------------|------HHI------|

A | osd1 | | | Blenders | | Encl ----------|----|---------------|
M |-------|______|----|____________| |________________| | |
___|__________________________________________________________|_______________|
VIU: Video Input Unit
---------------------
The Video Input Unit is in charge of the pixel scanout from the DDR memory.
It fetches the frames addresses, stride and parameters from the "Canvas" memory.
This part is also in charge of the CSC (Colorspace Conversion).
It can handle 2 OSD Planes and 2 Video Planes.
VPP: Video Post Processing
--------------------------
The Video Post Processing is in charge of the scaling and blending of the
various planes into a single pixel stream.
There is a special "pre-blending" used by the video planes with a dedicated
scaler and a "post-blending" to merge with the OSD Planes.
The OSD planes also have a dedicated scaler for one of the OSD.
VENC: Video Encoders
--------------------
The VENC is composed of the multiple pixel encoders :
- ENCI : Interlace Video encoder for CVBS and Interlace HDMI
- ENCP : Progressive Video Encoder for HDMI
- ENCL : LCD LVDS Encoder
The VENC Unit gets a Pixel Clocks (VCLK) from a dedicated HDMI PLL and clock
tree and provides the scanout clock to the VPP and VIU.
The ENCI is connected to a single VDAC for Composite Output.
The ENCI and ENCP are connected to an on-chip HDMI Transceiver.
Device Tree Bindings:
---------------------
VPU: Video Processing Unit
--------------------------
Required properties:
- compatible: value should be different for each SoC family as :

../soc/amlogic/amlogic,canvas.txt
Optional properties:
- power-domains: Optional phandle to associated power domain as described in
the file ../power/power_domain.txt
Required nodes:
The connections to the VPU output video ports are modeled using the OF graph
bindings specified in Documentation/devicetree/bindings/graph.txt.
The following table lists for each supported model the port number
corresponding to each VPU output.
Port 0 Port 1

Common Properties for Display Panel
===================================
This document defines device tree properties common to several classes of
display panels. It doesn't constitue a device tree binding specification by
itself but is meant to be referenced by device tree bindings.
When referenced from panel device tree bindings the properties defined in this
document are defined as follows. The panel device tree bindings are
responsible for defining whether each property is required or optional.
Descriptive Properties
----------------------
- width-mm,
- height-mm: The width-mm and height-mm specify the width and height of the
physical area where images are displayed. These properties are expressed in
millimeters and rounded to the closest unit.
- label: The label property specifies a symbolic name for the panel as a
string suitable for use by humans. It typically contains a name inscribed on
the system (e.g. as an affixed label) or specified in the system's
documentation (e.g. in the user's manual).
If no such name exists, and unless the property is mandatory according to
device tree bindings, it shall rather be omitted than constructed of
non-descriptive information. For instance an LCD panel in a system that
contains a single panel shall not be labelled "LCD" if that name is not
inscribed on the system or used in a descriptive fashion in system
documentation.
Display Timings
---------------
- panel-timing: Most display panels are restricted to a single resolution and
require specific display timings. The panel-timing subnode expresses those
timings as specified in the timing subnode section of the display timing
bindings defined in
Documentation/devicetree/bindings/display/panel/display-timing.txt.
Connectivity
------------
- ports: Panels receive video data through one or multiple connections. While
the nature of those connections is specific to the panel type, the
connectivity is expressed in a standard fashion using ports as specified in
the device graph bindings defined in
Documentation/devicetree/bindings/graph.txt.
- ddc-i2c-bus: Some panels expose EDID information through an I2C-compatible
bus such as DDC2 or E-DDC. For such panels the ddc-i2c-bus contains a
phandle to the system I2C controller connected to that bus.
Control I/Os
------------
Many display panels can be controlled through pins driven by GPIOs. The nature
and timing of those control signals are device-specific and left for panel
device tree bindings to specify. The following GPIO specifiers can however be
used for panels that implement compatible control signals.
- enable-gpios: Specifier for a GPIO connected to the panel enable control
signal. The enable signal is active high and enables operation of the panel.
This property can also be used for panels implementing an active low power
down signal, which is a negated version of the enable signal. Active low
enable signals (or active high power down signals) can be supported by
inverting the GPIO specifier polarity flag.
Note that the enable signal control panel operation only and must not be
confused with a backlight enable signal.
- reset-gpios: Specifier for a GPIO coonnected to the panel reset control
signal. The reset signal is active low and resets the panel internal logic
while active. Active high reset signals can be supported by inverting the
GPIO specifier polarity flag.
Power
-----
- power-supply: display panels require power to be supplied. While several
panels need more than one power supply with panel-specific constraints
governing the order and timings of the power supplies, in many cases a single
power supply is sufficient, either because the panel has a single power rail,
or because all its power rails can be driven by the same supply. In that case
the power-supply property specifies the supply powering the panel as a phandle
to a regulator.
Backlight
---------
Most display panels include a backlight. Some of them also include a backlight
controller exposed through a control bus such as I2C or DSI. Others expose
backlight control through GPIO, PWM or other signals connected to an external
backlight controller.
- backlight: For panels whose backlight is controlled by an external backlight
controller, this property contains a phandle that references the controller.

TPO TPG110 Panel
================
This panel driver is a component that acts as an intermediary
between an RGB output and a variety of panels. The panel
driver is strapped up in electronics to the desired resolution
and other properties, and has a control interface over 3WIRE
SPI. By talking to the TPG110 over SPI, the strapped properties
can be discovered and the hardware is therefore mostly
self-describing.
+--------+
SPI -> | TPO | -> physical display
RGB -> | TPG110 |
+--------+
If some electrical strap or alternate resolution is desired,
this can be set up by taking software control of the display
over the SPI interface. The interface can also adjust
for properties of the display such as gamma correction and
certain electrical driving levels.
The TPG110 does not know the physical dimensions of the panel
connected, so this needs to be specified in the device tree.
It requires a GPIO line for control of its reset line.
The serial protocol has line names that resemble I2C but the
protocol is not I2C but 3WIRE SPI.
Required properties:
- compatible : one of:
"ste,nomadik-nhk15-display", "tpo,tpg110"
"tpo,tpg110"
- grestb-gpios : panel reset GPIO
- width-mm : see display/panel/panel-common.txt
- height-mm : see display/panel/panel-common.txt
The device needs to be a child of an SPI bus, see
spi/spi-bus.txt. The SPI child must set the following
properties:
- spi-3wire
- spi-max-frequency = <3000000>;
as these are characteristics of this device.
The device node can contain one 'port' child node with one child
'endpoint' node, according to the bindings defined in
media/video-interfaces.txt. This node should describe panel's video bus.
Example
-------
panel: display@0 {
compatible = "tpo,tpg110";
reg = <0>;
spi-3wire;
/* 320 ns min period ~= 3 MHz */
spi-max-frequency = <3000000>;
/* Width and height from data sheet */

created for the OPTIMUS range of multi-gpu platforms. To userspace PRIME
buffers are dma-buf based file descriptors.
Overview and Driver Interface
-----------------------------
Overview and Lifetime Rules
---------------------------
Similar to GEM global names, PRIME file descriptors are also used to
share buffer objects across processes. They offer additional security:
as file descriptors must be explicitly sent over UNIX domain sockets to
be shared between applications, they can't be guessed like the globally
unique GEM names.
Drivers that support the PRIME API must set the DRIVER_PRIME bit in the
struct :c:type:`struct drm_driver <drm_driver>`
driver_features field, and implement the prime_handle_to_fd and
prime_fd_to_handle operations.
int (\*prime_handle_to_fd)(struct drm_device \*dev, struct drm_file
\*file_priv, uint32_t handle, uint32_t flags, int \*prime_fd); int
(\*prime_fd_to_handle)(struct drm_device \*dev, struct drm_file
\*file_priv, int prime_fd, uint32_t \*handle); Those two operations
convert a handle to a PRIME file descriptor and vice versa. Drivers must
use the kernel dma-buf buffer sharing framework to manage the PRIME file
descriptors. Similar to the mode setting API PRIME is agnostic to the
underlying buffer object manager, as long as handles are 32bit unsigned
integers.
While non-GEM drivers must implement the operations themselves, GEM
drivers must use the :c:func:`drm_gem_prime_handle_to_fd()` and
:c:func:`drm_gem_prime_fd_to_handle()` helper functions. Those
helpers rely on the driver gem_prime_export and gem_prime_import
operations to create a dma-buf instance from a GEM object (dma-buf
exporter role) and to create a GEM object from a dma-buf instance
(dma-buf importer role).
struct dma_buf \* (\*gem_prime_export)(struct drm_device \*dev,
struct drm_gem_object \*obj, int flags); struct drm_gem_object \*
(\*gem_prime_import)(struct drm_device \*dev, struct dma_buf
\*dma_buf); These two operations are mandatory for GEM drivers that
support PRIME.

Documentation Requirements for kAPI
-----------------------------------
All kernel APIs exported to other modules must be documented, including their
datastructures and at least a short introductory section explaining the overall
concepts. Documentation should be put into the code itself as kerneldoc comments
as much as reasonable.
Do not blindly document everything, but document only what's relevant for driver
authors: Internal functions of drm.ko and definitely static functions should not
have formal kerneldoc comments. Use normal C comments if you feel like a comment
is warranted. You may use kerneldoc syntax in the comment, but it shall not
start with a /** kerneldoc marker. Similar for data structures, annotate
anything entirely private with ``/* private: */`` comments as per the
documentation guide.

Driver Specific
===============
tinydrm
-------
Tinydrm is the helper driver for really simple fb drivers. The goal is to make
those drivers as simple as possible, so lots of room for refactoring:
- backlight helpers, probably best to put them into a new drm_backlight.c.
This is because drivers/video is de-facto unmaintained. We could also
move drivers/video/backlight to drivers/gpu/backlight and take it all
over within drm-misc, but that's more work. Backlight helpers require a fair
bit of reworking and refactoring. A simple example is the enabling of a backlight.
Tinydrm has helpers for this. It would be good if other drivers can also use the
helper. However, there are various cases we need to consider i.e different
drivers seem to have different ways of enabling/disabling a backlight.
We also need to consider the backlight drivers (like gpio_backlight). The situation
is further complicated by the fact that the backlight is tied to fbdev
via fb_notifier_callback() which has complicated logic. For further details, refer
to the following discussion thread:
https://groups.google.com/forum/#!topic/outreachy-kernel/8rBe30lwtdA
- spi helpers, probably best put into spi core/helper code. Thierry said
the spi maintainer is fast&reactive, so shouldn't be a big issue.
- extract the mipi-dbi helper (well, the non-tinydrm specific parts at
least) into a separate helper, like we have for mipi-dsi already. Or follow
one of the ideas for having a shared dsi/dbi helper, abstracting away the
transport details more.
