Reform 2 bringup progress: wall & battery power, usb, ethernet, audio, hdmi, reset all work. what doesn’t work: PCIe (no link), SD card (only some older, full size SD cards work). untested: MIPI DSI->eDP. most scary part because only experimental drivers exist.
@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.
@agx good timing :) i'm currently hacking on it. i'm using TI SN65DSI86, which has a mainline driver and seems pretty simple. i also picked some of your patches like https://source.puri.sm/Librem5/linux-next/commit/1a92d1145ec8ee9c7fe0376ed154594e429edd94
@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 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.
@agx thank you for this! i will attempt to integrate the code today. what is the role of mxsfb? is it a replacement/alternative to imx-drm? (i’m currently using a hacked up version of that with hdmi)
