DRM: Fix an incorrectly formatted table

2017-06-26T09:07:25+00:00

The "supported input formats" table in dw_hdmi.h was incorrectly formatted,
using "+" signs where "|" needs to be.  That, in turn, causes the PDF build
to fail.

drm/bridge/synopsys: dw-hdmi: Use bridge->mode_valid() callback

2017-06-05T06:39:50+00:00

Now that we have a callback to check if bridge supports a given mode
we can use it in Synopsys Designware HDMI bridge so that we restrict
the number of probbed modes to the ones we can actually display.

Also, there is no need to use mode_fixup() callback as mode_valid()
will handle the mode validation.

NOTE: I also had to change the pdata declaration of mode_valid
custom callback so that the passed modes are const. I also changed
in the platforms I found. Not even compiled it though.

drm: bridge: dw-hdmi: Move HPD handling to PHY operations

2017-04-04T15:48:21+00:00

The HDMI TX controller support HPD and RXSENSE signaling from the PHY
via it's STAT0 PHY interface, but some vendor PHYs can manage these
signals independently from the controller, thus these STAT0 handling
should be moved to PHY specific operations and become optional.

The existing STAT0 HPD and RXSENSE handling code is refactored into
a supplementaty set of default PHY operations that are used automatically
when the platform glue doesn't provide its own operations.

drm: bridge: dw-hdmi: Switch to V4L bus format and encodings

2017-04-04T15:48:21+00:00

Switch code to use the newly introduced V4L bus formats IDs instead of custom
defines. Also use the V4L encoding defines.

Some display pipelines can only provide non-RBG input pixels to the HDMI TX
Controller, this patch takes the pixel format from the plat_data if provided.

drm: bridge: dw-hdmi: Switch to regmap for register access

2017-03-10T10:07:47+00:00

The Synopsys Designware HDMI TX Controller does not enforce register
access on platforms instanciating it. The current driver supports two
different types of memory-mapped flat register access, but in order to
support the Amlogic Meson SoCs integration, and provide a more generic
way to handle all sorts of register mapping, switch the register access
to use the regmap infrastructure.

In the case of registers that are not flat memory-mapped or do not
conform to the current driver implementation, a regmap struct can be
given in the plat_data and be used at probe or bind.

Since the AHB audio driver is only available with direct memory access,
only allow the I2S audio driver to be registered is directly
memory-mapped.

drm: bridge: dw-hdmi: Remove device type from platform data

2017-03-10T10:06:38+00:00

The device type isn't used anymore now that workarounds and PHY-specific
operations are performed based on version information read at runtime.
Remove it.

drm: bridge: dw-hdmi: Add support for custom PHY configuration

2017-03-10T10:05:50+00:00

The DWC HDMI TX controller interfaces with a companion PHY. While
Synopsys provides multiple standard PHYs, SoC vendors can also integrate
a custom PHY.

Modularize PHY configuration to support vendor PHYs through platform
data. The existing PHY configuration code was originally written to
support the DWC HDMI 3D TX PHY, and seems to be compatible with the DWC
MLP PHY. The HDMI 2.0 PHY will require a separate configuration
function.

drm: bridge: dw-hdmi: Create PHY operations

2017-03-10T10:05:13+00:00

The HDMI TX controller support different PHYs whose programming
interface can vary significantly, especially with vendor PHYs that are
not provided by Synopsys. To support them, create a PHY operation
structure that can be provided by the platform glue layer. The existing
PHY handling code (limited to Synopsys PHY support) is refactored into a
set of default PHY operations that are used automatically when the
platform glue doesn't provide its own operations.
