Subject: [PATCH v2 0/4] Introduce ClockworkPi CWD686 DRM panel driver
Date: Sat,  3 Sep 2022 13:37:49 -0500	[thread overview]
Message-ID: <20220903183753.25736-1-max@maxfierke.com> (raw)

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 I have has two model numbers: TXW686001 and WTL068601G,
but cannot find any manufacturer associated with either, so opting 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 me.

[2] https://github.com/clockworkpi/DevTerm/blob/main/Code/patch/armbian_build_a06/patch/kernel-004-panel.patch

Thanks to Krzysztof Kozlowski, Rob Herring, and Sam Ravnborg for their
prior reviews and apologies for the long delay between patch set versions.

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
