The ClockworkPi DevTerm (all models) uses a 6.86" IPS display of unknown provenance, which uses the Chipone ICNL9707 IC driver[1].
The display panel Max Fierke has has two model numbers: TXW686001 and WTL068601G, but couldn’t find any manufacturer associated with either, so he opted for the ClockworkPi model number. This driver is based on the GPL-licensed driver released by ClockworkPi[1], authored by Pinfan Zhu, with some additional cleanup, rotation support, and display sleep re-enabling done by Max Fierke.

I hope this is the correct way of reviving old patches. Changes in v4: - Use existing clockwork vendor ID - Update the panel initalization code for DRM changes Changes in v3: - dt-bindings: add missing lines for spacing Changes in v2: - dt-bindings: remove redundant backlight example - add missing regulators - remove some unused properties from definition (e.g. enable_gpio, supply) - reorder includes - remove redundant ctx->backlight in favor of backlight through drm_panel_of_backlight - remove now-unneeded ctx->enabled and enable/disable hooks - replace ICNL9707_DCS macro with mipi_dsi_dcs_write_seq - use dev_err_probe instead of checking EPROBE_DEFER - fixed return type of cwd686_remove to be void following changes to mipi_dsi_driver - add .get_orientation callback
