drm/bridge/synopsys: dsi: extend the prototype of mode_valid()

2022-01-04T11:53:59+00:00

To evaluate the validity of a video mode, some additional internal
value has to be passed to the platform implementation.

Extend the prototype of mode_valid().

drm: bridge: dw-hdmi: Attach to next bridge if available

2021-07-28T13:33:13+00:00

On all platforms except i.MX and Rockchip, the dw-hdmi DT bindings
require a video output port connected to an HDMI sink (most likely an
HDMI connector, in rare cases another bridges converting HDMI to another
protocol). For those platforms, retrieve the next bridge and attach it
from the dw-hdmi bridge attach handler.

drm/bridge/synopsys: dw-hdmi: Add an option to suppress loading CEC driver

2021-04-20T15:22:38+00:00

This adds DW-HDMI driver a glue option to disable loading of the CEC sub-driver.

On some SoCs, the CEC functionality is enabled in the IP config bits, but the
CEC bus is non-functional like on Amlogic SoCs, where the CEC config bit is set
but the DW-HDMI CEC signal is not connected to a physical pin, leading to some
confusion when the DW-HDMI CEC controller can't communicate on the bus.

drm/bridge: dw-mipi-dsi: permit configuring the escape clock rate

2020-09-11T13:01:36+00:00

The Amlogic D-PHY in the Amlogic AXG SoC Family does support a frequency
higher than 10MHz for the TX Escape Clock, thus make the target rate
configurable.

drm: bridge: dw-hdmi: Pass drm_display_info to dw_hdmi_support_scdc()

2020-06-23T17:57:06+00:00

To prepare for making connector creation optional in the driver, pass
the drm_display_info explicitly to dw_hdmi_support_scdc(). The pointer
is passed to the callers where required, particularly to the
dw_hdmi_phy_ops .init() function.

drm: bridge: dw-hdmi: Pass drm_display_info to .mode_valid()

2020-06-23T17:56:02+00:00

Replace the drm_connector pointer passed to the .mode_valid() function
with a const drm_display_info pointer, as that's all the function should
need. Use the display info passed to the bridge .mode_valid() operation
instead of retrieving it from the connector, to prepare for make
connector creation optional.

drm: bridge: dw-hdmi: Pass private data pointer to .configure_phy()

2020-06-23T17:54:52+00:00

The .configure_phy() operation takes a dw_hdmi_plat_data pointer as a
context argument. This differs from .mode_valid() that takes a custom
private context pointer, causing possible confusion. Make the
dw_hdmi_plat_data operations more consistent by passing the private
context pointer to .configure_phy() as well.

drm: bridge: dw-hdmi: Pass private data pointer to .mode_valid()

2020-06-23T17:54:32+00:00

Platform glue drivers for dw_hdmi may need to access device-specific
data from their .mode_valid() implementation. They currently have no
clean way to do so, and one driver hacks around it by accessing the
dev_private data of the drm_device retrieved from the connector.

Add a priv_data void pointer to the dw_hdmi_plat_data structure, and
pass it to the .mode_valid() function.
