We need to augment the bindings for proper DRM integration: the timings are expressed by the hardware, not put into the device tree. I.e. this hardware is self-describing and can report the resolutions and timings needed. It should not be described in the device tree. Further the device was incorrectly modeled with GPIO lines instead of an SPI child, even though the device was using SPI. No known deployments of the device using device tree exist, so it should be fine to augment the bindings.

(Presumably OK since I just dropped a property and added nothing.) ChangeLog v2->v3: - Rewrite to reflect the fact that the display should be an SPI child device using 3WIRE SPI. ChangeLog v1->v2: - Expand some sections to make it clear what kind of device this is and that the serial protocol it uses is not I2C. --- .../bindings/display/panel/tpo,tpg110.txt | 81 ++++++++++++------- 1 file changed, 52 insertions(+), 29 deletions(-) diff --git a/Documentation/devicetree/bindings/display/panel/tpo,tpg110.txt b/Documentation/devicetree/bindings/display/panel/tpo,tpg110.txt index f5e3c6f2095a..40f3d7c713bb 100644 --- a/Documentation/devicetree/bindings/display/panel/tpo,tpg110.txt +++ b/Documentation/devicetree/bindings/display/panel/tpo,tpg110.txt @@ -1,47 +1,70 @@ TPO TPG110 Panel ================ -This binding builds on the DPI bindings, adding a few properties -as a superset of a DPI.

It is not a panel per se but a driver used with several low-cost noname panels. This is used on the Nomadik NHK15 combined with a OSD OSD057VA01CT display for WVGA 800x480. The driver is pretty minimalistic right now but can be extended to handle non-default polarities, gamma correction etc. The driver is based on the baked-in code in drivers/video/fbdev/amba-clcd-nomadik.c which will be decomissioned once this us upstream.
