4 years agodt-bindings: display: convert sharp,ls043t1le01 to DT Schema

dt-bindings: display: convert sharp,ls043t1le01 to DT Schema

The txt binding specified the property "power-supply".
But the example and the actual implementation in the linux-kernel
uses "avdd-supply".
So the binding is adjusted to use avdd-supply as this seems
to be the correct choice.
There are no DT files in the linux kernel to check.

4 years agodrm/dp_mst: Increase ACT retry timeout to 3s
Lyude Paul [Fri, 3 Apr 2020 19:47:15 +0000 (15:47 -0400)]
drm/dp_mst: Increase ACT retry timeout to 3s

Currently we only poll for an ACT up to 30 times, with a busy-wait delay
of 100µs between each attempt - giving us a timeout of 2900µs. While
this might seem sensible, it would appear that in certain scenarios it
can take dramatically longer then that for us to receive an ACT. On one
of the EVGA MST hubs that I have available, I observed said hub
sometimes taking longer then a second before signalling the ACT. These
delays mostly seem to occur when previous sideband messages we've sent
are NAKd by the hub, however it wouldn't be particularly surprising if
it's possible to reproduce times like this simply by introducing branch
devices with large LCTs since payload allocations have to take effect on
every downstream device up to the payload's target.

So, instead of just retrying 30 times we poll for the ACT for up to 3ms,
and additionally use usleep_range() to avoid a very long and rude
busy-wait. Note that the previous retry count of 30 appears to have been
arbitrarily chosen, as I can't find any mention of a recommended timeout
or retry count for ACTs in the DisplayPort 2.0 specification. This also
goes for the range we were previously using for udelay(), although I
suspect that was just copied from the recommended delay for link
training on SST devices.

Changes since v1:
* Use readx_poll_timeout() instead of open-coding timeout loop - Sean
  Paul
Changes since v2:
* Increase poll interval to 200us - Sean Paul
* Print status in hex when we timeout waiting for ACT - Sean Paul

drm/dp_mst: Remove drm_dp_mst_has_audio()

Drive-by fix I noticed the other day - drm_dp_mst_has_audio() only ever
made sense back when we still had to validate ports before accessing
them in order to (attempt to) avoid NULL dereferences. Since we have
proper reference counting that guarantees we always can safely access
the MST port, there's no use in keeping this function around as all it
does is validate the port pointer before checking the audio status.

Note - drm_dp_mst_port->has_audio is technically protected by
drm_device->mode_config.connection_mutex, since it's only ever updated
from drm_dp_mst_get_edid(). Additionally, we change the declaration for
port in struct intel_connector to be properly typed, so we can directly
access it.

order to (attempt to) safely access MST ports. However, we've since
improved how reference counting works with ports and mstbs such that we
can now rely on drm_dp_mst_port structs remaining in memory for as long
as the driver needs. This means we don't really need to cast this as

  - Drop changelog text and add reference (Daniel)
  - Improve grammar. and use "operation" (Laurent)

drm/dp_mst: Don't drop NAKs for down responses

It looks like that when we introduced the ability to handle multiple
down requests at once, we accidentally started dropping NAK replies -
causing sideband messages which got NAK'd to seemingly timeout and cause
all sorts of weirdness.

So, fix this by making sure we don't return from

  ever being called here
* Stop clearing aconnector->dc_sink - this also doesn't do anything
