drm/mediatek: Don't support hdmi connector creation

2021-04-01T14:05:20+00:00

commit f01195148967 ("drm/mediatek: mtk_dpi: Create connector for bridges")
broke the display support for elm device since mtk_dpi calls
drm_bridge_attach with the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR
while mtk_hdmi does not yet support this flag.

Fix this by accepting DRM_BRIDGE_ATTACH_NO_CONNECTOR in bridge attachment.
Implement the drm_bridge_funcs .detect() and .get_edid() operations, and
call drm_bridge_hpd_notify() to report HPD. This provides the
necessary API to support disabling connector creation.

In addition, the field 'conn' is removed from the mtk_hdmi struct since
mtk_hdmi don't create a connector. It is replaced with a pointer
'curr_conn' that points to the current connector which can be access
through the global state.

This patch is inspired by a similar patch for bridge/synopsys/dw-hdmi.c:
commit ec971aaa6775
("drm: bridge: dw-hdmi: Make connector creation optional")
But with the difference that in mtk-hdmi only the option of not creating
a connector is supported.

drm/mediatek: Switch the hdmi bridge ops to the atomic versions

2021-04-01T13:57:30+00:00

The bridge operation '.enable' and the audio cb '.get_eld'
access hdmi->conn. In the future we will want to support
the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR and then we will
not have direct access to the connector.
The atomic version '.atomic_enable' allows accessing the
current connector from the state.
This patch switches the bridge to the atomic version to
prepare access to the connector in later patches.

2021-03-31T11:38:06+00:00

This patch adds the missing MODULE_DEVICE_TABLE definitions on different
Mediatek drivers which generates correct modalias for automatic loading
when these drivers are compiled as an external module.

drm/mediatek: crtc: Make config-updating atomic

2021-03-29T16:02:58+00:00

While updating config, the irq would occur and get the partial
config, so use variable config_updating to make updating atomic.

drm/mediatek: cec: Delete redundant printing of return value

platform_get_irq() has already checked and printed the return value,
the printing here is nothing special, it is not necessary at all.
