First bits of fixes for the #librem5 (it uses another chip to drive the backlight than it's devkit) making it mainline already: https://lore.kernel.org/linux-leds/ba610ed3-19b7-3e10-7032-453e0cb05704@gmail.com/

@purism 's contributions to #linux 5.3 https://puri.sm/posts/purism-linux-5-3/ - there's more to come for 5.4 and 5.5.

@mntmn nice, so what was it?

@mntmn nice, the bridge should be attached by this https://source.puri.sm/guido.gunther/linux-imx8/blob/forward-upstream/next-20190823/mxsfb+nwl/v5/drivers/gpu/drm/bridge/nwl-dsi/nwl-drv.c#L226

@mntmn the sn64dsi86 wants your edp panel as output again (edp_panel_in) - i so far describe the chain only up to that. so its mxsfb -> nwl (drm bridge) -> ts65dsi86 (drm bridge) -> edp (drm panel). see ti_sn_bridge_probe. so your edp panel needs a panel entry within the ts65dsi86's dt node similar to what we do for our dsi panel within the nwl's bridge node: https://source.puri.sm/guido.gunther/linux-imx8/blob/imx8-5.x-drm/arch/arm64/boot/dts/freescale/imx8mq-librem5-devkit.dts#L849 - just a guess since i've not used the ts65dsi86.

@mntmn mxsfb used the lcdif interface instead of dcss which is way simpler and has (with robert's patches that i pulled into my tree) mainline support which dcss hasn't.

@mntmn it allows the mipi dsi host controller to use the iomuxc_gpr as mux controller since it needs to toggle between dcss and mxsfb input.

@mntmn you would just define a bridge for the sn65dsi as in the binding docs https://source.puri.sm/guido.gunther/linux-imx8/blob/forward-upstream/next-20190823/mxsfb+nwl/v5/Documentation/devicetree/bindings/display/bridge/ti,sn65dsi86.txt#L46 and use that as remote-endpoint in

https://source.puri.sm/guido.gunther/linux-imx8/blob/forward-upstream/next-20190823/mxsfb+nwl/v5/arch/arm64/boot/dts/freescale/imx8mq-librem5-devkit.dts#L757

and drop the panel altogether. So sd65sdi would have the nwl at it's port@0 while the nwl has the sn65dsi at it's port@1

@mntmn the version you picked is rather old and might not support bridge chaining.

@mntmn this one should have all the dtb, mxsfb and nwl patches: https://source.puri.sm/guido.gunther/linux-imx8/tree/forward-upstream/next-20190823/mxsfb+nwl/v5 - i've only used panel_bridge with that but ti,sn65dsi86 should work instead of that by swapping the panel out and the bridge in in dt.

@mntmn what are you using for dsi->eDP? The rest of the stack (mxsfb, nwl, mixel) should be in a reasonable shape with linux-next and the latest patches on the dri list.
