drm: bridge: Constify mode arguments to bridge .mode_set() operation

2019-01-14T01:51:14+00:00

The mode and ajusted_mode passed to the bridge .mode_set() operation
should never be modified by the bridge (and are not in any of the
existing bridge drivers). Make them const to make this clear.

drm/edid: Pass connector to AVI infoframe functions

2019-01-10T17:01:06+00:00

Make life easier for drivers by simply passing the connector
to drm_hdmi_avi_infoframe_from_display_mode() and
drm_hdmi_avi_infoframe_quant_range(). That way drivers don't
need to worry about is_hdmi2_sink mess.

v2: Make is_hdmi2_sink() return true for sil-sii8620
    Adapt to omap/vc4 changes

drm/msm/hdmi: Enable HPD after HDMI IRQ is set up

2018-12-03T13:46:13+00:00

SoCs that contain MDP5 have a top level wrapper called MDSS that
manages locks, power and irq for the sub-blocks within it.

Irq for HDMI is also routed through the MDSS.

Shortly after the Hot Plug Detection (HPD) is enabled in HDMI,
HDMI interrupts are recieved by the MDSS interrupt handler.
However at this moment the HDMI irq is still not mapped to
the MDSS irq domain so the HDMI irq handler cannot be called
to process the interrupts.

This leads to a flood of HDMI interrupts on CPU 0.

If we are lucky to have the HDMI initialization running on a
different CPU, it will eventually map the HDMI irq to MDSS irq
domain, the next HDMI interrupt will be handled by the HDMI irq
handler, the interrupt flood will stop and we will recover.

If the HDMI initialization is running on CPU 0, then it cannot
complete and there is nothing to stop the interrupt flood on
CPU 0. The system is stuck.

Fix this by moving the HPD enablement after the HDMI irq is
mapped to the MDSS irq domain.
