drm: rockchip: remove reference to non-existing config DRM_RGB

2021-08-26T09:19:08+00:00

commit 1f0f01515172 ("drm/rockchip: Add support for Rockchip Soc RGB
output interface") accidently adds to select the non-existing config
DRM_RGB in ./drivers/gpu/drm/rockchip/Kconfig.

Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs:

DRM_RGB
Referencing files: drivers/gpu/drm/rockchip/Kconfig

So, remove the reference to the non-existing config DRM_RGB.

drm/rockchip: dsi: add ability to work as a phy instead of full dsi

2021-07-25T15:19:49+00:00

SoCs like the rk3288 and rk3399 have 3 mipi dphys on them. One is TX-
only, one is RX-only and one can be configured to do either TX or RX.

The RX phy is statically connected to the first Image Signal Processor,
the TX phy is statically connected to the first DSI controller and
the TXRX phy is connected to both the second DSI controller as well
as the second ISP.

The RX dphy is controlled externally through registers in the "General
Register Files", while the other two are controlled through the
"Configuration and Test Interface" inside their DSI controller's
io-memory area.

The Rockchip dw-dsi controller already controls these dphys for the
TX case in the driver, but when we want to also allow configuration
for RX to the ISP from the media subsystem we need to expose phy-
functionality instead.

So add a bit of infrastructure to allow the dsi driver to work as a
phy and make sure it can be only one or the other at a time.

Similarly as the dsi-controller will be part of the drm-graph when
active, add an empty component to the drm-graph when in phy-mode
to make the rest of the drm-graph not wait for it.

drm/bridge/synopsys: dsi: driver-specific configuration of phy timings

2019-12-16T11:01:58+00:00

The timing values for dw-dsi are often dependent on the used display and
according to Philippe Cornu will most likely also depend on the used phy
technology in the soc-specific implementation.

To solve this and allow specific implementations to define them as needed
add a new get_timing callback to phy_ops and call this from the dphy_timing
function to retrieve the necessary values for the specific mode.

Right now this handles the hs2lp + lp2hs where Rockchip SoCs need handling
according to the phy speed, while STM seems to be ok with static values.

changes in v5:
- rebase on 5.5-rc1
- merge into px30 dsi series to prevent ordering conflicts

changes in v4:
- rebase to make it directly fit on top of drm-misc-next after all

changes in v3:
- check existence of phy_ops->get_timing in __dw_mipi_dsi_probe()
- emit actual error when get_timing() call fails
- add tags from Philippe and Yannick

changes in v2:
- add driver-specific handling, don't force all bridge users to use
  the same timings, as suggested by Philippe

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.
(Sound support is not included in this patch)

drm/rockchip: Add support for Rockchip Soc RGB output interface

2018-09-05T10:24:36+00:00

Some Rockchip CRTCs, like rv1108 and px30, can directly output parallel
and serial RGB data to panel or conversion chip.

So add a feature-bit for vops to mark the ability for these direct
outputs and add an internal encoder in that case, that can attach to
bridge chipsor panels.

Changes in v7:
    1. forget to delete rockchip_rgb_driver and delete it.
Changes in v6:
    1. Update according to Heiko Stuebner' implemention, rgb output is
       part of vop's feature, should not register as a independent
       driver.
Changes in v5:
    1. add SPDX-License-Identifier tag
Changes in v4:
    1. add support px30;
Changes in v3:
    1. update for rgb-mode move to panel node.
Changes in v2:
    1. add error log when probe failed;
    2. update name_to_output_mode() according to sean's suggest;
    3. Fix uninitialized use of ret.
