dt-bindings: display: mediatek: control dpi pins mode to avoid leakage

2020-06-20T08:24:15Z

[ Upstream commit b0ff9b590733079f7f9453e5976a9dd2630949e3 ] Add property "pinctrl-names" to swap pin mode between gpio and dpi mode. Set the dpi pins to gpio mode and output-low to avoid leakage current when dpi disabled. Acked-by: Rob Herring Signed-off-by: Jitao Shi Signed-off-by: Chun-Kuang Hu Signed-off-by: Sasha Levin

dt-bindings: display: sun4i: Add allwinner,tcon-channel property

2018-04-13T17:48:15Z

[ Upstream commit 22662f12768f971809b478386d9cc4947d00497a ] The Allwinner Timings Controller has two, mutually exclusive, channels. When the binding has been introduced, it was assumed that there would be only a single user per channel in the system. While this is likely for the channel 0 which only connects to LCD displays, it turns out that the channel 1 can be connected to multiple controllers in the SoC (HDMI and TV encoders for example). And while the simultaneous use of HDMI and TV outputs cannot be achieved, switching from one to the other at runtime definitely sounds plausible. Add an extra property, allwinner,tcon-channel, to specify for a given endpoint which TCON channel it is connected to, while falling back to the previous mechanism if that property is missing.

omapdrm: panel: fix compatible vendor string for td028ttec1

2018-03-24T10:00:25Z

[ Upstream commit c1b9d4c75cd549e08bd0596d7f9dcc20f7f6e8fa ] The vendor name was "toppoly" but other panels and the vendor list have defined it as "tpo". So let's fix it in driver and bindings. We keep the old definition in parallel to stay compatible with potential older DTB setup. Signed-off-by: H.

drm/sun4i: Add compatible string for A31/A31s TCON (timing controller)

2017-04-12T10:41:15Z

commit 93a5ec14da24a8abbac5bcb953b45cc7a5d0198a upstream. The A31 TCON has mux controls for how TCON outputs are routed to the HDMI and MIPI DSI blocks. Since the A31s does not have MIPI DSI, it only has a mux for the HDMI controller input. This patch only adds support for the compatible strings. Actual support for the mux controls should be added with HDMI and MIPI DSI support. Signed-off-by: Chen-Yu Tsai Signed-off-by: Maxime Ripard Signed-off-by: Greg Kroah-Hartman

drm/sun4i: Add compatible strings for A31/A31s display pipelines

2017-04-12T10:41:15Z

commit 49c440e87cd6f547f93d0dc53571ae0e11d9ec8f upstream. The A31's display pipeline has 2 frontends, 2 backends, and 2 TCONs. It also has new display enhancement blocks, such as the DRC (Dynamic Range Controller), the DEU (Display Enhancement Unit), and the CMU (Color Management Unit). It supports HDMI, MIPI DSI, and 2 LCD/LVDS channels. The A31s display pipeline is almost the same, just without MIPI DSI. Only the TCON seems to be different, due to the missing mux for MIPI DSI. Add compatible strings for both of them. Signed-off-by: Chen-Yu Tsai Acked-by: Rob Herring Signed-off-by: Maxime Ripard Signed-off-by: Greg Kroah-Hartman

drm/bridge: Add RGB to VGA bridge support

2016-10-10T05:28:44Z

Some boards have an entirely passive RGB to VGA bridge, based on DACs implemented by resistor ladders. Those might or might not have an i2c bus routed to the VGA connector in order to access the screen EDIDs. Add a bridge that doesn't do anything but expose the modes available on the screen, either based on the EDIDs if available, or based on the XGA standards.
