drm/bridge/lontium-lt9611uxc: move HPD notification out of IRQ handler

2021-01-28T10:54:50+00:00

drm hotplug handling code (drm_client_dev_hotplug()) can wait on mutex, thus delaying further lt9611uxc IRQ events processing. It was observed occasionally during bootups, when drm_client_modeset_probe() was waiting for EDID ready event, which was delayed because IRQ handler was stuck trying to deliver hotplug event. Move hotplug notifications from IRQ handler to separate work to be able to process IRQ events without delays.

drm/bridge/lontium-lt9611uxc: fix get_edid return code

2021-01-28T10:54:49+00:00

Return NULL pointer from get_edid() callback rather than ERR_PTR() pointer, as DRM code does NULL checks rather than IS_ERR(). Also while we are at it, return NULL if getting EDID timed out.

drm/bridge/lontium-lt9611uxc: fix waiting for EDID to become available

2021-01-28T10:54:49+00:00

- Call wake_up() when EDID ready event is received to wake wait_event_interruptible_timeout() - Increase waiting timeout, reading EDID can take longer than 100ms, so let's be on a safe side.

Because clk_disable_unprepare() already checked NULL clock parameter, so the additional check is unnecessary, just remove them. Signed-off-by: Xu Wang Reviewed-by: Laurent Pinchart Signed-off-by: Laurent Pinchart

drm/bridge: thc63lvd1024: Fix regulator_get_optional() misuse

2021-01-05T05:19:48+00:00

The thc63lvd1024 driver requests a supply using regulator_get_optional() but both the name of the supply and the usage pattern suggest that it is being used for the main power for the device and is not at all optional for the device for function, there is no handling at all for absent supplies. Such regulators should use the vanilla regulator_get() interface, it will ensure that even if a supply is not described in the system integration one will be provided in software.
