drm/amdgpu: use %u rather than %d for sclk/mclk

Large clock values may overflow and show up as negative.

drm/amdgpu/atomfirmware: fix vram_info fetching for renoir

2020-07-01T18:19:18+00:00

Renoir uses integrated_system_info table v12.  The table
has the same layout as v11 with respect to this data.  Just
reuse the existing code for v12 for stable.

Fixes incorrectly reported vram info in the driver output.

2020-07-01T05:40:58+00:00

Two fixups
- It fixes wrong return value by returing proper error value instead of
  fixed one.
- It fixes ref count leak in mic_pre_enable.
One cleanup
- It removes dev_err() call on platform_get_irq() failure because
  platform_get_irq() call dev_err() itself on failure.

drm/amd/display: Only revalidate bandwidth on medium and fast updates

2020-07-01T02:15:12+00:00

[Why]
Changes that are fast don't require updating DLG parameters making
this call unnecessary. Considering this is an expensive call it should
not be done on every flip.

DML touches clocks, p-state support, DLG params and a few other DC
internal flags and these aren't expected during fast. A hang has been
reported with this change when called on every flip which suggests that
modifying these fields is not recommended behavior on fast updates.

[How]
Guard the validation to only happen if update type isn't FAST.

drm: sun4i: hdmi: Remove extra HPD polling

2020-06-30T08:01:48+00:00

The HPD sense mechanism in Allwinner's old HDMI encoder hardware is more
or less an input-only GPIO. Other GPIO-based HPD implementations
directly return the current state, instead of polling for a specific
state and returning the other if that times out.

Remove the I/O polling from sun4i_hdmi_connector_detect() and directly
return a known state based on the current reading. This also gets rid
of excessive CPU usage by kworker as reported on Stack Exchange [1] and
Armbian forums [2].

drm/i915: Include asm sources for {ivb, hsw}_clear_kernel.c

2020-06-29T08:29:12+00:00

Alexandre Oliva has recently removed these files from Linux Libre
with concerns that the sources weren't available.

The sources are available on IGT repository, and only open source
tools are used to generate the {ivb,hsw}_clear_kernel.c files.

However, the remaining concern from Alexandre Oliva was around
GPL license and the source not been present when distributing
the code.

So, it looks like 2 alternatives are possible, the use of
linux-firmware.git repository to store the blob or making sure
that the source is also present in our tree. Since the goal
is to limit the i915 firmware to only the micro-controller blobs
let's make sure that we do include the asm sources here in our tree.

Btw, I tried to have some diligence here and make sure that the
asms that these commits are adding are truly the source for
the mentioned files:
