drm/rockchip: shutdown drm subsystem on shutdown

2019-04-18T08:28:30+00:00

As explained by Robin Murphy:
> the IOMMU shutdown disables paging, so if the VOP is still
> scanning out then that will result in whatever IOVAs it was using now going
> straight out onto the bus as physical addresses.

We had a more radical approach before in commit
7f3ef5dedb14 ("drm/rockchip: Allow driver to be shutdown on reboot/kexec")
but that resulted in new warnings and oopses on shutdown on rk3399
chromeos devices.

So second try is resurrecting Vicentes shutdown change which should
achieve the same result but in a less drastic way.

drm: rockchip: introduce rk3066 hdmi

2019-03-31T12:24:30+00:00

The RK3066 HDMI TX serves as interface between a LCD Controller and
a HDMI bus. A HDMI TX consists of one HDMI transmitter controller and
one HDMI transmitter PHY. The interface has three (3) 8-bit data channels
which can be configured for a number of bus widths (8/10/12/16/20/24-bit)
and different video formats (RGB, YCbCr).

Features:
HDMI version 1.4a, HDCP revision 1.4 and
DVI version 1.0 compliant transmitter.
Supports DTV resolutions from 480i to 1080i/p HD.
Master I2C interface for a DDC connection.
HDMI TX supports multiple power save modes.
The HDMI TX input can switch between LCDC0 and LCDC1.

drm/fbdev: Make skip_vt_switch the default

2019-03-26T15:24:26+00:00

KMS drivers really should all be able to restore their display state
on resume without fbcon helping out. So make this the default.

Since I'm not entirely foolish, make it only a default, which drivers
can still override. That way when the inevitable regression report
happens I can fix things up with a one-liner plus FIXME comment that
someone should fix up the suspend/resume code in that driver.

But at least all new drivers won't be broken by accident as soon as
you turn off fbcon because "suspend/resume worked when I tested it".

v2: Keep this for radeon because of

drm/rockchip: vop: reset scale mode when win is disabled

2019-03-18T17:58:12+00:00

NV12 framebuffers produced by the VPU shows distorted on RK3288
after win has been disabled when scaling is active.

This issue can be reproduced using a 1080p modeset by:
- Scale a 1280x720 NV12 framebuffer to 1920x1080 on win0
- Disable win0
- Display a 1920x1080 NV12 framebuffer without scaling on win0
- Output will now show the framebuffer distorted

And by:
- Scale a 1280x720 NV12 framebuffer to 1920x1080
- Change to a 720p modeset (win gets disabled and scaling reset to none)
- Output will now show the framebuffer distorted

Fix this by setting scale mode to none when win is disabled.
