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.

drm/rockchip: add CONFIG_OF dependency for lvds

2017-11-06T15:31:17+00:00

Build-testing on randconfig kernels revealed a dependency in the
newly added lvds sub-driver:

drivers/gpu/drm/rockchip/rockchip_lvds.c: In function 'rockchip_lvds_bind':
drivers/gpu/drm/rockchip/rockchip_lvds.c:380:24: error: 'struct drm_bridge' has no member named 'of_node'
   remote = lvds->bridge->of_node;

We could work around that in the code, adding a Kconfig dependency
seems easier.

This adds the respective Kconfig dependency.

drm/rockchip: fix Kconfig dependencies

2017-07-24T01:53:09+00:00

A bug that I had fixed earlier just came back, with CONFIG_EXTCON=m,
the rockchip drm driver will fail to link:

drivers/gpu/drm/rockchip/cdn-dp-core.o: In function `cdn_dp_get_port_lanes':
cdn-dp-core.c:(.text.cdn_dp_get_port_lanes+0x30): undefined reference to `extcon_get_state'
cdn-dp-core.c:(.text.cdn_dp_get_port_lanes+0x6c): undefined reference to `extcon_get_property'
drivers/gpu/drm/rockchip/cdn-dp-core.o: In function `cdn_dp_check_sink_connection':
cdn-dp-core.c:(.text.cdn_dp_check_sink_connection+0x80): undefined reference to `extcon_get_state'
drivers/gpu/drm/rockchip/cdn-dp-core.o: In function `cdn_dp_enable':
cdn-dp-core.c:(.text.cdn_dp_enable+0x748): undefined reference to `extcon_get_property'

The problem is that that the sub-drivers are now all linked into the
main rockchip drm module, which breaks all the Kconfig dependencies
that are specified in the options for those sub-drivers.

This clarifies the dependency to ensure that we can only turn on the DP
driver when EXTCON is reachable. As the 'select' statements can now
cause additional options to become built-in when they should be
loadable modules, I'm moving those into the main driver config option.
The dependency on DRM_ROCKCHIP can be reduced into a single 'if'
statement here for brevity, but this has no functional effect.

Currently we are adding all components from the dts, if one of their
drivers been disabled, we would not be able to bring up others.

Refactor component match logic, follow exynos drm.
