I'm sending this early, as my continuing journey into fatherhood is occurring really soon now, I'm going to be mostly useless for the next couple of weeks, though I may be able to read email, I doubt I'll be doing much patch applications or git sending. If anything urgent pops up I've asked Daniel/Jani/Alex/Sean to try and direct stuff towards you. Outside drm changes: Some rcar-du updates that touch the V4L tree, all acks should be in place. It adds one export to the radix tree code for new i915 use case. There are some minor AGP cleanups (don't see that too often). Changes to the vbox driver in staging to avoid breaking compilation.

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)

|
|||
The Allwinner A10 Display pipeline is composed of several components
|
||||
that are going to be documented below:
|
||||
|
||||
For the input port of all components up to the TCON in the display
|
||||
pipeline, if there are multiple components, the local endpoint IDs
|
||||
must correspond to the index of the upstream block. For example, if
|
||||
the remote endpoint is Frontend 1, then the local endpoint ID must
|
||||
be 1.
|
||||
For all connections between components up to the TCONs in the display
|
||||
pipeline, when there are multiple components of the same type at the
|
||||
same depth, the local endpoint ID must be the same as the remote
|
||||
component's index. For example, if the remote endpoint is Frontend 1,
|
||||
then the local endpoint ID must be 1.
|
||||
|
||||
Conversely, for the output ports of the same group, the remote endpoint
|
||||
ID must be the index of the local hardware block. If the local backend
|
||||
is backend 1, then the remote endpoint ID must be 1.
|
||||
Frontend 0 [0] ------- [0] Backend 0 [0] ------- [0] TCON 0

|
||||
Frontend 1 [1] ------- [1] Backend 1 [1] ------- [1] TCON 1
|
||||
|
||||
For a two pipeline system such as the one depicted above, the lines
|
||||
represent the connections between the components, while the numbers
|
||||
within the square brackets corresponds to the ID of the local endpoint.
|
||||

The same rule also applies to DE 2.0 mixer-TCON connections:

Vertical Blanking
|
||||
=================
|
||||
|
||||
Vertical blanking plays a major role in graphics rendering. To achieve
|
||||
tear-free display, users must synchronize page flips and/or rendering to
|
||||
vertical blanking. The DRM API offers ioctls to perform page flips
|
||||
synchronized to vertical blanking and wait for vertical blanking.
|
||||
|
||||
The DRM core handles most of the vertical blanking management logic,
|
||||
which involves filtering out spurious interrupts, keeping race-free
|
||||
blanking counters, coping with counter wrap-around and resets and
|
||||
keeping use counts. It relies on the driver to generate vertical
|
||||
blanking interrupts and optionally provide a hardware vertical blanking
|
||||
counter. Drivers must implement the following operations.
|
||||
|
||||
- int (\*enable_vblank) (struct drm_device \*dev, int crtc); void
|
||||
(\*disable_vblank) (struct drm_device \*dev, int crtc);
|
||||
Enable or disable vertical blanking interrupts for the given CRTC.
|
||||
|
||||
- u32 (\*get_vblank_counter) (struct drm_device \*dev, int crtc);
|
||||
Retrieve the value of the vertical blanking counter for the given
|
||||
CRTC. If the hardware maintains a vertical blanking counter its value
|
||||
should be returned. Otherwise drivers can use the
|
||||
:c:func:`drm_vblank_count()` helper function to handle this
|
||||
operation.
|
||||
|
||||
Drivers must initialize the vertical blanking handling core with a call
|
||||
to :c:func:`drm_vblank_init()` in their load operation.
|
||||
|
||||
Vertical blanking interrupts can be enabled by the DRM core or by
|
||||
drivers themselves (for instance to handle page flipping operations).
|
||||
The DRM core maintains a vertical blanking use count to ensure that the
|
||||
interrupts are not disabled while a user still needs them. To increment
|
||||
the use count, drivers call :c:func:`drm_vblank_get()`. Upon
|
||||
return vertical blanking interrupts are guaranteed to be enabled.
|
||||
|
||||
To decrement the use count drivers call
|
||||
:c:func:`drm_vblank_put()`. Only when the use count drops to zero
|
||||
will the DRM core disable the vertical blanking interrupts after a delay
|
||||
by scheduling a timer. The delay is accessible through the
|
||||
vblankoffdelay module parameter or the ``drm_vblank_offdelay`` global
|
||||
variable and expressed in milliseconds. Its default value is 5000 ms.
|
||||
Zero means never disable, and a negative value means disable
|
||||
immediately. Drivers may override the behaviour by setting the
|
||||
:c:type:`struct drm_device <drm_device>`
|
||||
vblank_disable_immediate flag, which when set causes vblank interrupts
|
||||
to be disabled immediately regardless of the drm_vblank_offdelay
|
||||
value. The flag should only be set if there's a properly working
|
||||
hardware vblank counter present.
|
||||
|
||||
When a vertical blanking interrupt occurs drivers only need to call the
|
||||
:c:func:`drm_handle_vblank()` function to account for the
|
||||
interrupt.
|
||||
|
||||
Resources allocated by :c:func:`drm_vblank_init()` must be freed
|
||||
with a call to :c:func:`drm_vblank_cleanup()` in the driver unload
|
||||
operation handler.
