drm: bridge: dw_hdmi: add reset function for PHY GEN1

2022-04-19T16:19:03+00:00

PHY reset register(MC_PHYRSTZ) active high reset control for PHY GEN2, and active low reset control for PHY GEN1. Rename function dw_hdmi_phy_reset to dw_hdmi_phy_gen2_reset.

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.

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.

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.

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.
