The Hummingbird A31 board has a VGA DAC which converts RGB output
from the LCD interface to VGA analog signals.
Add nodes for the VGA DAC, its power supply, and enable this part
of the display pipeline.

Hi,
This is v4 of my sun6i DRM/KMS display enablement series. It adds
regulator support to the dumb-vga-dac bridge and enables the VGA
output on the A31 Hummingbird.
Changes since v3:
- Add Rob's Ack.
- Fix up enable/disable callbacks as Archit suggested.
- Dropped pinmux settings for G
7;s definitely doable, it just takes some effort.

You can use those planes to do composition too, with each application
having one or more plane. Android uses that.
There's no argument to have a cursor plane, really. Even regular
graphic stack like X can use a regular overlay to have its cursor on
it. It doesn't *remove* anything, it just allows to use the plane for
what it was supposed to be used for.

If we attempt to read/write the TCON registers before the bus clock
is enabled, those accesses get ignored.
In practice this almost never occurs because U-boot had already enabled
the bus clock as part of its firmware provided framebuffer (simplefb).

The sun4i DRM driver counts the number of endpoints it found and

However, if the TCON and its child endpoints (LCD panels, TV encoder,
HDMI encoder, MIPI DSI encoder, etc.) aren't found, that means we
don't have any usable CRTCs, and the

As it turns out, on cards that actually have CRTCs on them we're already
calling drm_kms_helper_poll_enable(drm_dev) from
nouveau_display_resume() before we call it in
nouveau_pmops_runtime_resume(). This leads us to accidentally trying to
enable polling twice, which results in a potential deadlock

Sumit still takes care about dma-buf, but we've merged the trees
together since way too much overlap. And Gustavo is also part of the
drm-misc team to be able to help out.

KS happened, time to make this official!
Well, scripting work to make this all happen is still ongoing, but I'm
trying to at least keep the new tree semi-in-sync with the temporary
topic/drm-misc branch in the drm-intel.git repo. So for now still no
new committers, and existing ones still need to

Load palette at the end of mode_set_nofb() and only if the palette has
not been loaded since last runtime resume. Moving the palette loading
to mode_set_nofb() saves us from storing and restoring of LCDC dma
addresses that were just recently updated.

The LCDC revision 2 documentation also mentions the mandatory palette
for true color modes. Even if the rev 2 LCDC appears to work just fine
without the palette being loaded loading it helps in testing the
feature.

Revision 1 of the IP doesn't work if we don't load the palette (even
if it's not used, which is the case for the RGB565 format).
Add a function called from tilcdc_crtc_enable() which performs all
required actions if we're dealing with a rev1 chip.

Changes since first version of the series:
- Move tilcdc_regs.h changes from "drm/tilcdc: Enable palette loading
for revision 2 LCDC too" to "drm/tilcdc: Add tilcdc_write_mask() to
tilcdc_regs.h"

Hi Dave,
Just a few bug fixes for 4.9. The big one is Mario's prime fencing fix.
