Hi Dmitry,
It looks like there are some issues with this patchset... :/ I just
fetched the drm-tip and, with these patches included, the "Hot plug
detection already enabled" warning is back for i.MX DCSS.
After a short investigation, it seems that we end up calling
drm_bridge_hpd_enable() from bo

So, let's remove that call.

Hi Liang,
Thanks for the patch.
The patch is ok but, since you're at it, maybe add of_node_put() in the
dcss_dev_destroy() too?

Not sure if it's worth the effort but, since DCSS is a completely
self-contained driver, maybe it would be good to split this patch in 2
as well.

Hi Liu Ying,
I promised I would have a second, more in-depth, look at this and I finally
managed to do it.
I have to admit it was a challenge. Partially because I'm not very familiar
with DPU but mostly because of the abundance of macros used. It's true, macros
make the code more compact. However

I think the SN65DSI86 driver is exactly what you should focus on, so
that it works when connector is optional. The ADV7511/AD

Hi Liu Ying,
I gave this a first look but, since this is a huge piece of code and I'm not
very familiar with DPU, I'll probably give it another pass next week.
Anyway, some comments/questions inline.

Glad to see this series out. However, something went wrong with it as
patch 5/8 didn't make it to dri-devel mailing list... :/

This patch adds support for using NN interpolation scaling by setting the
SCALING_FILTER plane property to 1. Otherwise, the default method is used.

Also, make sure to allow full rotations for DRM_FORMAT_MOD_VIVANTE_SUPER_TILED.

Use div_s64() for the 64-bit divisions. This would allow the driver to compile
on 32-bit architectures, if needed.
